Mon, 09 Apr 2012 08:35:21 EDT nws.social.media@noaa.gov http://www.spc.noaa.gov/products/outlook/day2otlk.html The stage is set for another round of severe thunderstorms across the central and southern Great Plains on Monday. The NWS Storm Prediction Center (SPC) is already highlighting a Slight Risk for severe storms from southwest Kansas into the Texas Panhandle, eastward into eastern Oklahoma and northeast Texas. The initial threat will develop during the mid/late afternoon hours, where large hail (potentially significant in size), damaging winds in excess of 60 mph and isolated tornadoes are possible. By evening, storms will evolve into primarily a damaging wind threat, especially across western Oklahoma and the adjacent parts of Texas. Sun, 08 Apr 2012 14:41:00 EDT nws.social.media@noaa.gov http://www.srh.noaa.gov/graphicast.php?site=maf&gc=1 A cold front and associated dryline will be the focus for severe thunderstorms this afternoon through late tonight. The best threat will be across far southeast New Mexico and West Texas into south central Oklahoma. The primary risks include large hail and damaging winds in excess of 60 mph, however isolated tornadoes, locally heavy rainfall and frequent cloud to ground lightning are also possible. By Sunday, the threat for isolated strong to severe storms will stretch from south central New Mexico to northeast Texas. Sat, 07 Apr 2012 08:07:52 EDT nws.social.media@noaa.gov http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=usa&wwa=Freeze%20Warning Tonight will be the last in a string of unseasonably cold nights in the Ohio Valley, Mid-Atlantic and Northeast. Usually these temperatures would pass unnoticed, but the unusually warm March has accelerated the growing season and exposed delicate vegetation to a harmful freeze. Caretakers of vegetation are urged to take protective measures tonight. Fri, 06 Apr 2012 20:03:06 EDT nws.social.media@noaa.gov http://go.usa.gov/RRX An intensifying storm over the northern High Plains will bring increasing snow and winds across the northern Rockies through tonight and into early Saturday. Snow accumulations across eastern Idaho into central Montana will range from 5 to 9 inches in the valleys and 10 to 20 inches in the high terrain. Strong winds will combine with the heavy snow to create blizzard conditions across central Montana. This will create hazardous travel conditions and add stress to newborn livestock in the region. Fri, 06 Apr 2012 09:10:11 EDT nws.social.media@noaa.gov http://www.wrh.noaa.gov/FXC/wxstory.php?wfo=ggw Snow and strong winds will continue to spread into eastern Idaho and central Montana through Friday. Snow accumulations of 5 to 9 inches are expected in the valley locations, with accumulations of 10 to 20 inches in the higher terrain. Blizzard conditions are expected in north-central Montana. Thu, 05 Apr 2012 20:34:03 EDT nws.social.media@noaa.gov http://go.usa.gov/Rvk The NWS Storm Prediction Center has indicated a Slight Risk of severe thunderstorms today into tonight across a large portion of the southeastern U.S. The primary risks are large hail and damaging winds, though isolated tornadoes are also possible.

Wed, 04 Apr 2012 08:27:46 EDT nws.social.media@noaa.gov http://go.usa.gov/Rvk The NWS Storm Prediction Center has indicated a Slight Risk of severe thunderstorms across parts of the southern Plains, western Ozarks and lower Mississippi Valley. There is also a Slight Risk of severe thunderstorms across parts of the mid-Mississippi and Ohio Valleys. The primary risks are very large hail, damaging winds and isolated tornadoes. Isolated strong storms are also possible today across the southeastern United States. Tue, 03 Apr 2012 09:41:45 EDT nws.social.media@noaa.gov http://www.spc.noaa.gov/products/outlook/ On Monday there were reports of an EF-1 tornado in eastern Texas and trees and power lines downed across the Deep South leaving more than 6,000 residents in the dark. Storms are still ongoing across the central and southern Great Plains, and are expected to continue into tonight. The Storm Prediction Center is forecasting more severe weather for the southern Plains tomorrow. Mon, 02 Apr 2012 21:04:41 EDT http://go.usa.gov/Rvk The NWS Storm Prediction Center has indicated a Slight Risk of severe thunderstorms across a large part of Texas northward into parts of the central Plains, as well as parts of the lower Mississippi Valley. Large hail should be the dominant risk, although some potential also will exist for tornadoes, especially in southwestern Kansas and western Oklahoma. Mon, 02 Apr 2012 09:07:04 EDT http://www.hpc.ncep.noaa.gov/html/sfc2.shtml The orange colored front in the central and southern Great Plains depicted on the Hydrometeorological Prediction Center Surface Chart is the “dry line”. East of the dry line, dew point temperatures are in the 60s to 70s, while to the west, dew point temperatures are in the teens. This boundary is in the area where storms are expected to form on Monday. Sun, 01 Apr 2012 18:52:23 EDT http://www.spc.noaa.gov/products/fire_wx/fwdy1.html Critical fire weather conditions are likely today for the central/southern Rockies into the western Great Plains (from the Canadian to Mexican borders). The more intense conditions are expected from southeast CO into southern NM and West Texas, where exceptional drought conditions still persist in some areas. Relative humidity of 5-20 percent will combine with west/southwest winds of 20-30 mph and gusts up to 40 mph during the afternoon (locally stronger in portions of NM). By late in the day, a cold front will move into the northern/central Great Plains, shifting winds to a northwesterly direction, which may impact ongoing fires. Temperatures today will be the warmest across eastern NM and West Texas, where 80s to lower 90s will be common. Sun, 01 Apr 2012 09:19:19 EDT nws.social.media@noaa.gov http://www.spc.noaa.gov/products/fire_wx/overview.html The North Fork, Colorado fire is finally 90% contained after burning 4,140 acres. Fire weather danger is still at the critical level for Sunday for portions of eastern Colorado, as well as western Oklahoma, west Texas and much of New Mexico. Very dry conditions and winds sustained at 40 to 50 mph, gusting to 70mph, will quickly spread any fire that may start in this area. Sat, 31 Mar 2012 21:42:25 EDT http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Back-to-back Pacific storm systems are bringing bouts of heavy rainfall, strong winds and heavy mountain snow to the West Coast. Recent rainfall amounts of 3 to 7 inches were common, especially over southwest Oregon and northwest California. An additional 3 to 5 inches of rainfall is expected in these areas through Saturday. Several rivers and streams are already experiencing flooding. Also, strong winds will gust up to 60 mph which could bring down trees and power lines. Fri, 30 Mar 2012 20:15:29 EDT nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Strong winds may cause travel issues and power outages across much of the southwest today. Wind gusts topping 70mph are possible. To the north, heavy rainfall will continue along the Central Pacific Coast over the next several days. Some roads in the area are already closed due to flooding. Fri, 30 Mar 2012 11:06:42 EDT http://www.spc.noaa.gov A weather system moving through the central portions of the U.S. today will bring a threat for strong to severe storms across the central Great Plains and the Mid-Mississippi River Valley. This includes eastern NE, southern IA, northern MO, eastern KS and central OK, where the primary risks will be large hail and damaging winds, although an isolated tornado can not be ruled out. By Friday, the weather disturbance will migrate east, shifting the focus for severe thunderstorms to the Ohio River Valley. The aforementioned risks will stretch from east central IL to central OH and northern KY. A few strong storms are also possible in the Mid- and Lower Mississippi River Valley as well as the southern Great Plains. Thu, 29 Mar 2012 16:58:21 EDT nws.social.media@noaa.gov http://www.wrh.noaa.gov/FXC/wxstory.php?wfo=mfr A series of Pacific storms will impact the Pacific Northwest and northern California through Saturday, leading to heavy precipitation and strong winds. The heaviest precipitation is expected across southwest Oregon and northwest California, where 9 to 11 inches, with locally heavier amounts, are possible. Moderate to major flooding is likely on several rivers in this region, including the Coquille River. This will also increase the risk for mudslides. The combination of strong winds (gusts up to 65 mph) and saturated soils from this week's precipitation may cause downed trees and power lines. Remember: Turn Around Don't Drown Wed, 28 Mar 2012 19:12:28 EDT nws.social.media@noaa.gov http://www.nwrfc.noaa.gov/rfc/ A storm system will continue to affect southern Oregon and northern California through Wednesday. This disturbance will be responsible for heavy rain and mountain snow (measured in feet) as well as gusty winds across the region. Hazardous driving conditions are likely in the high terrain due to near white-out and snow-packed road conditions. Meanwhile, significant river rises and flooding is possible in the coastal areas due to heavy rain over already saturated soils and high water levels. Tue, 27 Mar 2012 18:49:54 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/bou/?n=wildfire-necomarch262012 The Lower North Fork Fire in the foothills southwest of Denver, Colorado was ignited yesterday amid Extremely Critical Fire Weather Conditions marked by strong winds and low humidity. The wildfire quickly spread out of control and has now consumed at least 3050 acres. Smoke from the fire has been causing air quality concerns in Denver. Weather conditions will remain warm, dry and occasionally windy over the next several days. The fire is zero percent contained, and at least 450 firefighters are either on-site or en-route to join the containment efforts. Tue, 27 Mar 2012 10:30:20 EDT nws.social.media@noaa.gov http://graphical.weather.gov/images/centgrtlakes/MinT1_centgrtlakes.png After an extended period of record-breaking warmth across the central and eastern United States, high pressure will usher in colder air into the Great Lakes, Ohio Valley and Mid-Atlantic regions tonight. Low temperatures are forecast to range from the lower 20s to the lower 30s at several locations. With an early growing season already in progress, any vegetation susceptible to freezing temperatures over an extended period of time may be at risk to severe damage. In addition, pets should be brought indoors during the overnight. Mon, 26 Mar 2012 17:25:12 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/wxstory.php?site=cys A storm system in the northern Rockies is causing strong winds in the High Plains today. The air is very dry, and temperatures are again unseasonably warm. This combination is making fire weather conditions extremely critical. Any fires that do develop would quickly spread out of control, especially across eastern Colorado, southeast Wyoming and the Nebraska Panhandle. Mon, 26 Mar 2012 09:12:48 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/news/display_cmsstory.php?wfo=lot&storyid=80803&source=0 The string of days with unprecedented warmth is coming to an end for many locations in the Great Lakes and Northeast as a cold front ushers in more seasonable temperatures. The Plains and Lower Ohio Valley will remain warm through the middle of next week. The record warmth has accelerated the onset of the growing season by more than a month, and this makes crops vulnerable to a hard freeze. Fri, 23 Mar 2012 21:32:19 EDT nws.social.media@noaa.gov http://go.usa.gov/Rvk The NWS Storm Prediction Center has indicated a Slight Risk of severe thunderstorms over the Lower Ohio River Valley, as well as portions of central and southern Illinois.

Mon, 19 Mar 2012 09:45:47 EDT nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/national_forecast/natfcst.php A storm system moving out of the Rockies will bring a plethora of weather hazards to the central U.S. on Monday. First, strong winds and low humidity will create critical fire weather conditions across the western Great Plains. Meanwhile, a cold front will be the focus for severe thunderstorms from the Middle Mississippi Valley to the Lower Rio Grande Valley, or from Iowa to eastern Texas. Large hail, damaging winds and tornadoes are all possible. To complicate matters, torrential rain is possible over areas of saturated soils, which may lead to flash flooding. The focus will generally stretch from southwest Missouri into northeast and east central Texas. Expect the severe thunderstorm and heavy rainfall threats to shift east for Tuesday. Sun, 18 Mar 2012 18:49:35 EDT nws.social.media@noaa.gov http://www.ready.gov/natural-disasters Over the next few days, there will be an increased chance for severe weather in the central U.S. On Sunday, the greatest threat will be in the central and southern Great Plains. A strong cold front will push through the central U.S. on Monday, moving the greatest threat for severe weather eastward into the eastern portions of the central and southern Plains and into the Mississippi Valley. Do you know what to do when faced with severe weather Sun, 18 Mar 2012 06:57:02 EDT http://www.hpc.ncep.noaa.gov/national_forecast/natfcst.php A storm system will bring persistent rain, heavy mountain snow and strong winds to California and the Great Basin tonight.

Mon, 20 Feb 2012 07:05:44 EST nws.social.media@noaa.gov http://www.spc.noaa.gov/products/fire_wx/overview.html The storm system moving through the center of the country has brought windy conditions and widespread snow to the Rockies. Ahead of the cold front, winds will pick up across the southern plains on Monday. Dry conditions combined with sustained wind speeds of 20-40 mph, gusts to 60mph, will cause blowing dust and elevated fire weather conditions. Should a fire start in this area, it has the potential to spread quickly. Sun, 19 Feb 2012 21:17:27 EST http://graphical.weather.gov/sectors/conus.php?element=SnowAmt Heavy snow is now falling across portions of the central Appalachians as the storm system that brought severe weather to the south yesterday lifts northeast. Precipitation from this fast moving event will likely continue over the Mid-Atlantic coast through very early Monday morning. However, in the wake of the storm, sunny skies will prevail for much of Monday. Sun, 19 Feb 2012 17:34:09 EST http://www.hpc.ncep.noaa.gov/qpf/excess_rain.shtml A potent disturbance in the Southern Plains coupled with abundant moisture has already brought heavy rainfall to the western and central Gulf Coast. As the system moves northeast, expect precipitation, heavy at times, to spread into the eastern Gulf Coast, Southeast and portions of the southern Mid-Atlantic states through Sunday afternoon. Rainfall amounts of one to two inches will be common across the region, with locally heavier amounts up to three inches possible. This will pose a risk of flooding across the region. Remember: Turn Around Don't Drown Sat, 18 Feb 2012 21:04:48 EST nws.social.media@noaa.gov http://www.spc.noaa.gov/products/outlook/day1otlk.html Heavy rain and thunderstorms over the southern plains and lower Mississippi Valley will continue to press eastward ahead of an organizing storm system. Some storms may be severe. Flooding is also a concern for much of the south today and tomorrow. Along the northern portion of the storm, heavy snowfall is possible Sunday as this system lifts northeast into the much colder air filtering into the central Appalachians and central Mid-Atlantic. Sat, 18 Feb 2012 06:44:23 EST http://www.hpc.ncep.noaa.gov/wwd/winter_wx.shtml#snow A storm system in north central Mexico will rapidly intensify this weekend and race east/northeast across the Gulf Coast toward the Carolinas. While this system will bring a threat for severe thunderstorms and heavy rainfall to the Gulf Coast and Southeast on Saturday, there is an additional threat for heavy snow across the eastern Ohio Valley and the central Appalachians Saturday night into Sunday. Wet snowfall in excess of four inches coupled with strong winds may lead to hazardous winter weather conditions. Winter Storm Watches have already been posted for eastern Kentucky, southern West Virginia and western Virginia. Fri, 17 Feb 2012 19:57:48 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd A developing storm system over the Southeast will bring severe weather and possible snow to parts of the eastern U.S. this weekend.

Hazardous conditions could develop to the south of the snow, across portions of the central and lower Mississippi Valley, where periods of sleet and freezing rain are likely. Mon, 13 Feb 2012 08:59:44 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd A broad area of light snow and freezing rain will invade portions of the Southern and Central Plains through Monday. One to three inches of snow are expected from the Texas Panhandle to the Middle Mississippi River Valley, along with up to a tenth of an inch of freezing rain. This will be enough to pose a travel hazard for a large portion of the central United States. Meanwhile, another night of sub-freezing temperatures is in store for the Southeast and much of Florida Sunday night. Sun, 12 Feb 2012 10:54:43 EST nws.social.media@noaa.gov http://www.srh.noaa.gov/graphicast.php?site=mob Hard Freeze Warnings have been posted for tonight across much of the Gulf Coast from eastern Texas into northern Florida. A substantially colder air mass behind an arctic front will impact the region, where temperatures in the upper teens and 20s will be common. Sub-freezing readings can be expected for a period of 6 to 12 hours across the region. Prematurely blooming or emerging plants are at risk of damage if not properly protected. Some exposed pipes may be susceptible to freezing and should be protected. Pets should have warm shelter or be brought inside. Sat, 11 Feb 2012 08:12:59 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Light to occasionally moderate snow will impact the Great Lakes and Rocky Mountains today.

Very strong winds ahead of this system will be the main concern. Additionally, the system will bring some light rain to the San Joaquin Valley and light snow to the Sierra Nevada and Tehachapi Mountains above 5000 feet. High wind warnings will be in effect at least through Tuesday morning. Mon, 06 Feb 2012 19:40:58 EST http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd The National Hurricane Center in Miami has issued a Special Tropical Weather Outlook for the North Atlantic, Caribbean Sea and the Gulf of Mexico. A weak disturbance north of Cuba will bring locally heavy rain to southern Florida today. Rainfall amounts of 1-2 inches are likely, leading to ponding of water in poor drainage areas. This system has a low chance of becoming a subtropical cyclone during the next 48 hours. Mon, 06 Feb 2012 09:57:44 EST nws.social.media@noaa.gov http://www.nhc.noaa.gov/gtwo_atl.shtml A non-tropical low pressure system is interacting with an upper-level trough, producing showers and thunderstorms across of much of west and central Cuba, the lower Florida Keys. A surface circulation is becoming better defined just west of the western tip of Cuba. Heavy rainfall and gusty winds are expected to impact southern Florida and the Florida Keys over the next couple of days. Sun, 05 Feb 2012 19:45:12 EST http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd A rather low-impact weather day is forecast for most of the country today. The storm system that brought blizzard conditions to the Plains has weakened and is rapidly moving through the eastern half of the country bringing areas of rain to the Southeast and Mid-Atlantic. Meanwhile, western Alaska has been experiencing blizzard conditions as a storm churns in the Bering Sea, but conditions will steadily improve today. Sun, 05 Feb 2012 07:02:59 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/national_forecast/natfcst.php The same storm system that brought blizzard conditions to portions of the Central Plains will weaken while moving into the eastern U.S. this evening. The strong winds and heavy snow will gradually diminish, but showers and strong thunderstorms will continue to move across the southeastern U.S. tonight. Rain may be moderate to heavy at times. In the meantime, temperatures should be cold enough to support light snow in the higher elevations of the central Appalachians tonight and Sunday. Sat, 04 Feb 2012 17:07:09 EST nws.social.media@noaa.gov http://radar.weather.gov/Conus/Loop/southmissvly_loop.gif Widespread moderate to heavy rain is possible this afternoon across the Lower Mississippi River Valley as a cold front tracks across the region. The combination of abundant moisture and slow-moving precipitation will lead to rainfall amounts ranging from 1 to 3 inches, with locally higher amounts possible. The heavy rainfall over already saturated soils may contribute to flash flooding. Remember: Turn Around Don't Drown. Sat, 04 Feb 2012 11:51:50 EST nws.social.media@noaa.gov http://www.crh.noaa.gov/wxstory.php?site=lbf Very heavy snow will continue through Saturday afternoon across the Central Plains. The greatest accumulations of 1 to 2 feet will be found from northeast Colorado into southern Nebraska and northwest Kansas. Relatively lighter snowfall amounts will fall over central Kansas and western Iowa. Northerly winds of 15-25 mph with gust over 40 mph will create blizzard conditions over portions of northeast Colorado into southwest Nebraska. Travel will be impossible and extremely dangerous in this region. Fri, 03 Feb 2012 20:05:27 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Heavy snow is possible today across parts of the central Plains and central High Plains, with 1 to 2 feet of snow expected in the Denver area.

Snow will rapidly develop across the Plains later tonight and become widespread on Friday. This storm will be slow moving, so a prolonged period of moderate to heavy snow will persist into early Saturday morning. Snowfall rates of 1 to 2 inches per hour coupled with wind gusts up to 50 mph will create blizzard and life-threatening weather conditions across the region. Thu, 02 Feb 2012 19:32:17 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd What will become a large storm system over the central and southern Rockies is currently organizing out west and will bring heavy snow with strong winds, severe weather and heavy rain to parts of the central U.S. over the next couple of days. Thu, 02 Feb 2012 09:51:48 EST nws.social.media@noaa.gov http://www.ready.gov/winter-weather A Pacific system is forecast to bring a significant winter storm to the central Rockies and adjacent Great Plains from Thursday through Saturday. Heavy snowfall (locally in excess of one foot) is possible across eastern Colorado, southeast Wyoming, northwest Kansas, and Nebraska.

Mon, 28 Nov 2011 07:06:41 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd A cold front is expected to sweep across the northern Plains during the weekend, following a Thanksgiving that saw clear skies across much of the country and record highs in the central U.S. that were as much as 30 degrees above normal. The cold front is forecast to be quite strong as it moves steadily across the Midwest and into the southern Plains, with much lower temperatures and showers and thunderstorms accompanying it. Showers are forecast from the Great Lakes to the Gulf coast on Saturday, with snow possible across the Upper Midwest. As the system moves eastward on Sunday, the chance of rain will shift to the eastern U.S., with a chance of snow across much of the Great Lakes. Thu, 24 Nov 2011 23:52:57 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Rain and higher elevation snow will develop over parts of northern and central California on Thanksgiving, ending by the evening hours. Rain will also develop over parts of the southern Rockies and southern High Plains Thanksgiving night into Friday. In addition, a new front will begin to move onshore over the Pacific Northwest during the afternoon and early evening on Thanksgiving, producing coastal rain and higher elevation snow across the region, with snow moving into the northern Rockies by Friday. Meanwhile, much of the eastern two-thirds of the country will be under the influence of high pressure, bringing clear skies during Thanksgiving Day. Thu, 24 Nov 2011 12:21:20 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd The strong storm that has been affecting the Pacific Northwest will taper off today, but yet another storm is expected to bring a round of strong winds to the region on Thanksgiving Day. Wind gusts to 97 mph were reported along the Oregon coast yesterday, and up to 85 mph in mountain passes and canyons. Meanwhile, in the eastern U.S., rainfall is diminishing from south to north across the Mid-Atlantic this morning, but rainfall and high-elevation snow will continue across New England though the afternoon. A total 4 to 8 inches of snow, along with pockets of light freezing rain, is expected to fall by this afternoon across the higher elevations of upstate New York and across Vermont/New Hampshire into Maine, making travel difficult. Low Ceilings, poor visibility, and gusty winds are expected to cause significant delays to air traffic and affect major airports of the Mid-Atlantic and Northeast today. Wed, 23 Nov 2011 08:00:01 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd A very active weather pattern is in store through Thanksgiving, with two systems dominating. The first will bring heavy rainfall and the risk of flooding from Ark. into southern Mo. and southern Ill. through midday Tues. As the system pushes eastward, it will bring moderate to heavy precipitation across the Ohio Valley and Mid-Atlantic by Tues. evening, along with a threat for severe thunderstorms from the Gulf Coast up into the Ohio Valley through early Wed. morning. As this system moves toward New England on Wed., it will bring a wintry mix of precipitation, with a mixture of snow and freezing rain possible from upstate N.Y. into upper New England. Total snow accumulations of 4 to 8 inches, with only minor ice accumulations of up to a tenth of an inch, are forecast at this time. Meanwhile, an active Pacific storm track will keep precipitation in the forecast through Thurs. morning, mostly from northern Calif. up into the Pacific Northwest. Tue, 22 Nov 2011 08:32:46 EST nws.social.media@noaa.gov http://www.hpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd Two systems will impact travel across the U.S. this holiday week. In the southern U.S., there is a potential for flooding Monday afternoon from southeast Oklahoma to western Tennessee. Severe thunderstorms are expected to develop Monday night into Tuesday over central and north Texas and from western Tennessee to Mississippi to Louisiana and to the coast of Texas on Tuesday afternoon. On Wednesday through Thursday, showers and thunderstorms will develop from Georgia to the central Gulf Coast. Showers and thunderstorms will develop over the southern Plains on Saturday, moving into the Southeast on Sunday. Damaging winds are possible along the coastal ranges of Oregon and Washington Monday and Tuesday, as well as across the northern and southern Rocky Mountains for Monday afternoon through Wednesday evening. In the Northeast, there is a potential for rain or snow on Wednesday. Fair, breezy and cooler weather will return for Thanksgiving. Mon, 21 Nov 2011 08:28:58 EST nws.social.media@noaa.gov http://www.wrh.noaa.gov/ A very active pacific storm track will continue to draw a series of upper-level disturbances inland across the Pacific Northwest into the weekend. As a result, the Shasta and Oregon cascades can expect near a foot of snowfall accumulation, with additional snowfall spreading over the Wasatch and Tetons. Overall, the dominant precipitation type across the western U.S. with these systems will be snow, as plenty of cold air has worked its way from western Canada down into the west. However, coastal and valley locations across the region can expect rain, given their lower elevations. Meanwhile, a strong upper low lurking off the coast of the San Francisco bay area will quickly deteriorate conditions along the California coast by late Saturday and early Sunday.

Tue, 27 Sep 2011 17:02:46 EDT nws.social.media@noaa.gov http://www.nhc.noaa.gov/ The remnants of Tropical Storm Ophelia — currently a low pressure system centered a couple of hundred miles east-northeast of the northern Leeward Islands — is producing a large area of showers and thunderstorms. Surface and satellite observations indicate that the system has a broad circulation and upper-level winds appear somewhat conducive for additional redevelopment as the low moves slowly northwestward during the next day or two. This system has a high chance — 80 percent — of regenerating into a tropical cyclone during the next 48 hours. Meanwhile, Tropical Storm Philippe continues to move northwestward — about 735 miles west of the Cape Verde Islands — with little change in strength. Tue, 27 Sep 2011 08:07:04 EDT nws.social.media@noaa.gov http://www.nhc.noaa.gov/ Ophelia has degenerated to the point where it lacks sufficient organized, deep convection to be classified as a tropical cyclone and has become a remnant low pressure area a couple hundred miles east of the northern Leeward Islands. Meanwhile, Tropical Storm Philippe, which formed during the weekend over the far eastern Atlantic, is located about 600 miles west of the southernmost Cape Verde Islands. Philippe is moving toward the west-northwest at about 13 mph with maximum sustained winds near 60 mph. A turn toward the northwest with a decrease in forward speed is expected during the next couple of days. Philippe poses no threat to land at this time. Mon, 26 Sep 2011 08:23:34 EDT nws.social.media@noaa.gov http://www.noaawatch.gov/floods.php An upper-level low over the Ohio Valley is expected to bring a steady flow of tropical moisture up the Eastern Seaboard through the weekend. This enhanced moisture content, combined with a slow-moving frontal boundary, should lead to widespread rainfall across the eastern U.S. Flooding and flash flooding are possible from parts of North Carolina into lower New England, including major metropolitan areas such as Washington, D.C., Philadelphia, New York, and Boston. Many regions hit hard by recent heavy precipitation events this month may see additional moderate to heavy rainfall. Flood and Flash Flood Watches and Flood Warnings are in effect from North Carolina northeastward into Massachusetts. Fri, 23 Sep 2011 08:13:14 EDT nws.social.media@noaa.gov http://www.noaawatch.gov/floods.php Scattered showers and thunderstorms will be likely across the eastern U.S. over the next several days, bringing the possibility of flooding across parts of the Mid-Atlantic into southern New England. Remember, it takes only two feet of rushing water to carry away most vehicles, so if you if you encounter a flooded roadway, Turn Around Don’t Drown®.

Tue, 28 Jun 2011 08:16:52 EDT nws.social.media@noaa.gov http://www.srh.noaa.gov/abq/ The wind-driven Las Conchas wildfire has forced the closure of the Los Alamos National Laboratory in New Mexico, as well as the evacuation of about 100 people. U.S. Forest Service officials said that the fire has burned at least six square miles and was threatening buildings, power lines and natural gas lines. The fire has come within about one mile to the southwest of the government laboratory. High temperatures, low humidity and high wind are contributing to o the intense fire behavior and rapid fire growth. Mon, 27 Jun 2011 08:21:37 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/bis/ Flood waters continue to increase into Minot, N.D., with about 15-20% of the city inundated with water and flood waters expected to increase in the coming days. About 12,000 residents have been evacuated from the previously-identified flood zones. Officials are considering additional evacuations as projections worsen. Water is flowing toward Minot from Canada faster than ever, due to record water levels upstream. The current forecast is for the crest to reach between 1,564 and 1,565 feet above sea level sometime during the overnight hours of June 25-26, and continuing through June 30. This crest would be more than 6 feet above record flood stage, and 9 feet above major flood stage. Fri, 24 Jun 2011 08:11:02 EDT nws.social.media@noaa.gov http://water.weather.gov/ahps/rfc/rfc.php The levees in the City of Minot, N.D., continue to overtop with Souris River waters, with evacuations underway. The levees will continue to be overtopped as river levels continue to rise, with the river forecast to exceed historical record levels early Friday and crest on Sunday. Souris River levels throughout Minot are likely to fluctuate until water has filled the storage behind the levees. Meanwhile, evacuations are also underway in nearby Burlington, N.D., where the Souris River is overtopping its levees. The Missouri River also continues to rise, and levee breaches are a major concern in Missouri, Kansas, Iowa, and Nebraska. Interstate 29 has been shut down in several locations in Iowa and Missouri. Every bridge crossing from St. Joseph, Mo., to Omaha, Neb., has been closed. Thu, 23 Jun 2011 08:23:49 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/bis/ Flood control measures along the Souris River in North Dakota have reached their limit, and flooding is occurring in Minot, N.D. Flooded areas are expected to be inundated for several months. Earlier today, the Minot Emergency Operations Center reported levees beginning to over top in parts of Minot. Mandatory evacuations have been ordered along the Souris river through a significant portion of the city, affecting up to 12,000 people. The National Weather Service office in Bismark, N.D., issued a Flash Flood warning this morning and stated that those in the mandatory evacuation zones need to move to higher ground now.

Wed, 22 Jun 2011 11:20:13 EDT nws.social.media@noaa.gov http://www.crh.noaa.gov/bis/ Record-breaking flooding on the Souris River near Minot, N.D., has forced the ordered evacuation of 12,000 residents. Levee protection in the city of Minot averages a height of 1,558 feet, with some low spots between 1,556 and 1,558 feet. Based on no additional rainfall, no unexpected changes in upstream releases, and no unforeseen breaches or failures of levees, the current forecast suggests the 1,556 foot level will be reached sometime this afternoon and that the record level of 1,558 feet will be broken, fully overtopping the levees by Thursday morning. Meanwhile, in Williston, N.D., the Missouri River is at 30.6 feet, 2.5 feet above the previous record, with only 1.5 feet remaining before the levee protecting Williston becomes overtopped. The current forecast has the river cresting and falling to 30 feet by tomorrow afternoon.

Mon, 20 Jun 2011 20:26:05 EDT nws.social.media@noaa.gov http://www.wrh.noaa.gov/firewx/main.php Strong southwest winds and single digit relative humidity have caused difficult firefighting conditions for fire crews on both the Wallow and Monument fires in eastern Arizona. The Wallow Fire has burned more than 511,000 acres and is 51% contained. Evacuations remain in effect for the communities of Sunrise, Greer and Blue River, Ariz. Southwest winds have pushed the fire into far western New Mexico, threatening the town of Luna. Meanwhile, strong southwest winds have also pushed the Monument Fire further into the wildland urban interface just south of Sierra Vista, Ariz., limiting the ability of fire agencies to utilize aircraft to help stop the blaze. High pressure will build into the western U.S. this week, resulting in lighter winds and warmer temperatures. Mon, 20 Jun 2011 05:07:07 EDT nws.social.media@noaa.gov http://radar.srh.noaa.gov/fire/ The Wallow Fire continues to burn in Arizona and New Mexico, consuming 487,016 acres.
