Summary

A tornado outbreak occurred over parts of northern and central Oklahoma during the day on May 24, 2011, with violent tornadoes devastating several communities. By the end of the day, one EF-5, two EF-4, and two EF-3 tornadoes destroyed buildings, ripped up trees and power poles, and unfortunately, resulted in 11 deaths and 293 injuries.

The day began with a strong upper level trough ejecting out of the southwestern United States. The trough took on a negative tilt as it approached the southern Plains. A strong jet stream was located at both the middle and upper levels rotating around the upper trough. At the surface, a low pressure strengthened rapidly over northwestern Oklahoma, keeping the low-level flow of warm, moist air to flow east of a dry line that had moved into western Oklahoma.

Thunderstorms developed by early afternoon over western Oklahoma, and quickly became supercells as they moved northeast. Strong low-level rotation developed early, with the first tornado occurring over Blaine County, and moved northeast into Major County. Another supercell rapidly gained low-level rotation as it moved from Caddo into Canadian County. This tornado became the strongest of them all as it moved north of El Reno, west of Piedmont, and to south of Guthrie in Logan county. Nine people died as a result of this violent tornado.

Two more powerful supercells developed over Grady county, and they moved northeast into McClain and Cleveland counties. Finally, the final tornado occurred east of Norman into Pottawatomie county. The timing of this outbreak could not have come at a worse time, as rush hour was just unfolding as the tornadoes neared the Oklahoma City metro area.

Fast Facts

Twelve tornadoes occurred during the outbreak within the NWS Norman forecast area with another 10 tornadoes occurring within the NWS Tulsa forecast area..

One tornado has been rated EF-5. Two tornadoes were rated EF-4. Two tornadoes were rated EF-3, two EF-2, two EF-1, and three EF-0.

In addition to the damaging tornadoes, hail sizes reached at least 3" in diameter.

The NWS Norman Forecast Office did not evacuate or take shelter during May 24, 2011 tornado oubtreak. While safety and back-up plans were in place and could have been implemented had we felt an imminent threat, the forecast staff maintained their positions and warning operations continued uninterrupted.

The mesonet station located 5 miles west-northwest of El Reno in Canadian measured a wind gust of 151 mph and a 1-minute average wind speed of 115 mph. This was associated with one of the violent tornadoes that moved from near Binger to near Guthrie, OK. In addition to the incredible wind gust, the site also recorded a large and sudden drop in atmospheric pressure. This is the highest wind gust recorded by a Mesonet station, breaking the previous record of 113 mph set at the Lahoma (Major County, OK) site on August 17, 1994. The the meteogram that shows the high wind gust was provided courtesy of the Oklahoma Mesonet). You can also find more information in an Oklahoma Mesonet news article.

Tornado A1 - The "Canton Lake Tornado" of May 24, 2011

Tornado Number	Date	Time (CST)	Length of Path (miles)	Width of Path (yards)	F-Scale	Killed	Injured	County	Location
A1	05/24/2011	1420-1444	13	880	EF3	1	2	Dewey/ Blaine/ Major	3 W Canton - Canton Lake - 6 WSW Fairview

This large tornado began west of Canton in Dewey County and moved north-northeast toward (and eventually over) Canton Lake. The damage was confined to trees and power poles/lines during the early stages of the tornado. However, more significant damage occurred as the tornado moved into Blaine County.

The tornado moved northeast toward Canton Lake, which is where more significant damage occurred. Near the lake, on both sides where the tornado crossed, significant tree damage occurred. Numerous trailer homes were knocked over or destroyed. On the south side of the lake, two injuries occurred at the Canadian Campground. Several other campers took shelter in a concrete bathhouse. Although the bathhouse sustained damage, no injuries were reported. Other concrete structures (benches, pick-nick tables, etc.) were knocked over or shattered. On the other side of the lake, southwest of Longdale, significant damage continued to more structures and trees.

The tornado then continued to move almost due north into Major County and hit homesteads and barns, severely damaging most structures, and splintering trees and power poles. One of the farmsteads received on the upper end of EF-3 damage, with the house completely collapsing and the trees on the property debarked and snapped. The tornado continued near Cedar Springs, damaging the church roof, and severely damaging a mobile home and several buildings at a farmstead. The tornado finally lifted southwest of Fairview.

Tornado B2 - The "Calumet-El Reno-Piedmont-Guthrie Tornado" of May 24, 2011

Tornado Data

Tornado Number	Date	Time (CST)	Length of Path (miles)	Width of Path (yards)	F-Scale	Killed	Injured	County	Location
B2	05/24/2011	1450-1635	63	1760	EF5	9	181	Canadian/ Kingfisher/ Logan	4 ESE Hinton (14 SW Calumet) - near Calumet - El Reno - Piedmont - Cashion - 4 NE Guthrie

This tornado began very close to the Caddo/Canadian County border and quickly became a strong/violent tornado. The tornado destroyed numerous trees, many of them were debarked, before crossing U.S. Interstate Highway 40. Three people died in vehicles near the I-40 Calumet exit, and two other fatalities occurred just northeast of that location. Cars were thrown thousands of feet off the roadways. It is believed that the tornado reached its maximum intensity just after crossing I-40, and it was here that a mobile radar measured winds of greater than 210 mph just off the surface.

The highest wind gust ever recorded at an Oklahoma Mesonet site was measured near El Reno, as an EF-5 tornado tore a path through Canadian County. The wind speed increased from 61 mph at 4:18 PM CDT, to 66 mph at 4:19 PM CDT, to 131 mph at 4:20 PM CDT, to 151 at 4:21 PM CDT, and then to 91 mph at 14:22 PM CDT. The tornado caused considerable damage to the area surrounding the Mesonet as it moved northeast.

As the tornado continued northeast, it narrowly missed the town of Piedmont. Widespread EF-3, occasional EF-4 damage occurred between El Reno and Piedmont. More widespread EF-4 damage was seen west and north of Piedmont. Especially hard hit was the Falcon Lake neighborhood, near the Kingfisher County border. Two children were killed at this location. The tornado continued into southeastern Kingfisher County.

The tornado entered far southeast Kingfisher County before moving into Logan County. However, EF-3 damage occurred just over the Kingfisher county border, debarking trees and significantly damaging buildings. As the tornado continued northeast, the damage was mainly considered EF-2, with damage to mostly outbuildings and trees.

The tornado moved into Logan County and resulted in two additional fatalities (both of whom were outside when the tornado struck) near Cashion. The tornado destroyed several manufactured homes (both double and single-wide) after entering Logan county. Large high-transmission line tresses collapsed. Trees were debarked with only stumps remaining. Several buildings had most of their exterior walls collapse, with only the inner walls remaining. EF-2 to occasionally EF-3 damage occurred as the tornado neared Guthrie. Luckily, most of the town of Guthrie was spared to the tornado as it moved west and then north of the center of the city. Finally, the tornado dissipated northeast of Guthrie with some minor tree damage. After it was all said and done, the tornado continued for 63 miles, and lasted around an hour and 45 minutes. Monetary damage estimates were not available.

Tornado C1 - The "Chickasha-Blanchard-Newcastle Tornado" of May 24, 2011

Tornado Data

Tornado Number	Date	Time (CST)	Length of Path (miles)	Width of Path (yards)	F-Scale	Killed	Injured	County	Location
C1	05/24/2011	1606-1701	33	880	EF4	1	48	Grady/ McClain/ Cleveland	2 S Chickasha - SW Oklahoma City (near SW 149th and Portland)

This tornado formed on the south side of Chickasha in Grady County, quickly producing EF-2 damage. Mobile homes were damaged and destroyed, trees were uprooted/destroyed, outbuildings were destroyed, and many buildings lost significant portions of their roofs. One fatality occurred as a mobile home was destroyed in the south portion of Chickasha. As the tornado moved northeast of Chickasha, it gained significant strength, with several areas receiving EF-4 damage. Well-built homes were destroyed. Trees were debarked with only stumps remaining. Cars were thrown hundreds of feet. Almost continuous EF-3/occasional EF-4 damage occurred northeast until it crossed into McClain County 1.5 miles south of Highway 9. The tornado was probably at its strongest as it neared/crossed the McClain county line. Wind speeds there were estimated near 200 mph.

Significant damage continued as the violent tornado crossed over the McClain County line. This may have been the strongest portion of this tornado, with wind speeds near 200 mph. Well-built homes were destroyed, with some cleaned off of their foundation. A concrete dome home was severely damage, mainly by the flying debris. Trees were debarked or destroyed. Very little was left standing for the first few miles into McClain County. Fairly consistent EF-3, with brief periods of EF-4 damage occurred as the tornado neared/crossed Highway 9, near the Highway 76 junction. The tornado began to weaken as it moved toward the Cleveland County border, with mainly trees and power poles/lines snapped.

As the tornado continued into Cleveland County, only minor tree/power pole/power line damage occurred just inside the Cleveland County line. A few barns and outbuilding also sustained minor damage east of I-44. The tornado dissipated just north of the Canadian River. After it was finally over, the tornado continued for just under an hour, with a length of around 32 miles. Peak wind speeds were estimated just under 200 mph. Monetary damage estimates were not available.

The tornado was several hundred yards wide as it neared the county line. Luckily, very few structures were in the path.

Widespread tree damage and ground scouring was ongoing as the tornado crossed into McClain County. As the tornado crossed Highway 76, even more intense damage occurred. EF-4 damage was surveyed at several locations. Several homes were reduced to a pile of rubble, or were wiped clean off of their foundations. Automobiles were mangled and almost unrecognizable. The tornado weakened and narrowed as it crossed CR 410. Even though the tornado had weakened, EF-2 to EF-3 damage was still occurring as it approached OK State Highway 39.

The tornado increased in intensity once again near the Highway, with EF-4 damage surveyed for the 2nd time. Well constructed homes were destroyed, with several wiped clean off of their foundations. This also began a longer streak of higher end damage, with EF-3 to EF-4 damage occurring until it crossed OK State Highway 74B, west of High Avenue. Equally devastating destruction occurred over the areas of EF-4 damage. The tornado lifted west of Goldsby with still EF-3 damage occurring prior to lifting. It should be noted that this tornado had estimated winds up to 200 mph at times, falling just short of the damage indicator for an EF-5 tornado. Monetary damage estimates were not available.

This tornado developed west-southwest of the intersection of Fishmarket Road and Memorial Road to the south-southwest of McLoud. The tornado moved east-northeast where a telephone company building lost its roof, and a number of sheds were damaged and causing tree damage as it crossed the intersection and Fishmarket and Memorial Roads. Extensive tree damage continued northeast of this intersection, at least one home suffered the destruction of an attached garage and a few homes suffered roof and window damage. The tornado turned north-northeast crossing U.S. Interstate 40 near the Walker Road bridge where it struck and semi truck, lifting and destroying the trailer, lofting the pieces to the north, and injuring the truck driver.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...TODAY AND TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON THROUGH
THIS EVENING ACROSS MOST OF CENTRAL AND NORTH CENTRAL OKLAHOMA.

LOCATION...
THE HIGH RISK AREA IS NORTH AND EAST OF A LINE FROM CENTRAHOMA... TO
PAULS VALLEY... TO CHICKASHA... TO CHEROKEE. THERE IS ALSO A
MODERATE RISK SOUTH AND WEST OF THE HIGH RISK AREA AND EAST OF A
LINE FROM HENRIETTA TEXAS... TO HINTON... TO ALVA. AND... THERE IS A
SLIGHT RISK WEST OF THE MODERATE RISK AND EAST OF A LINE FROM ARCHER
CITY TEXAS... TO GRANDFIELD... TO WEATHERFORD... TO FREEDOM.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM 3 PM
THROUGH MIDNIGHT.

IMPACTS...
THE POTENTIAL EXISTS FOR LARGE... STRONG... LONG-TRACK TORNADOES IN
THE HIGH RISK AREA. DESTRUCTIVE HAIL... POSSIBLY LARGER THAN
BASEBALLS... AND DAMAGING STRAIGHT LINE WINDS ALSO WILL BE POSSIBLE
IN THE RISK AREAS.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS... EMERGENCY MANAGEMENT PERSONNEL... AND ALL
EMERGENCY RESPONSE AGENCIES ARE ENCOURAGED TO MAINTAIN A HIGH STATE
OF READINESS THROUGHOUT THE DAY... AND SHOULD BE PREPARED FOR A
POSSIBLE OUTBREAK OF SEVERE WEATHER. PLAN FOR SEVERE WEATHER
OPERATIONS AS SOON AS EARLY THIS AFTERNOON... AND POSSIBLY LASTING
WELL INTO THE NIGHT.

AN OUTBREAK OF SEVERE WEATHER IS EXPECTED. PEOPLE IN OKLAHOMA AND
WESTERN NORTH TEXAS SHOULD PAY CLOSE ATTENTION TO WEATHER CONDITIONS
TODAY AND LISTEN FOR LATER FORECASTS...WATCHES AND WARNINGS.

DISCUSSION...
OUTFLOW FROM THUNDERSTORMS LATE MONDAY SPREAD SOUTH ACROSS ALL OF
OKLAHOMA OVERNIGHT. THE OUTFLOW BOUNDARY STALLED NEAR THE RED RIVER
IN THE PRE-DAWN HOURS. THE STORMS THAT GENERATED THE BOUNDARY
WEAKENED AND DISSIPATED DURING THE EVENING. AS A RESULT... THE
OUTFLOW BOUNDARY ALSO WILL WEAKEN THIS MORNING.

AN UNSEASONABLY STRONG UPPER-LEVEL STORM SYSTEM FOR LATE SPRING...
LOCATED OVER ARIZONA EARLY THIS MORNING... WILL MOVE QUICKLY EAST
AND WILL PUNCH INTO WESTERN OKLAHOMA BY EARLY EVENING. A SURFACE LOW
WILL DEEPEN OVER SOUTHWESTERN KANSAS AHEAD OF THE UPPER SYSTEM. THE
SURFACE LOW ALSO WILL BECOME VERY INTENSE FOR LATE MAY. THE
STRENGTHENING LOW WILL PRODUCE STRONG SOUTH WINDS OVER THE AREA
TODAY... WHICH WILL DRAW MOIST AND UNSTABLE AIR NORTHWARD OVER TEXAS
AND OKLAHOMA. DAYTIME HEATING WILL LEAD TO STRONG TO EXTREME
INSTABILITY THIS AFTERNOON... BY WHICH TIME A DRY LINE OVER WEST
TEXAS WILL MOVE EAST INTO WESTERN OKLAHOMA. THE DRY LINE IS FORECAST
TO BE NEAR THE WESTERN EDGE OF THE SLIGHT RISK AREA BY MID
AFTERNOON. A CAPPING LAYER OF WARM AIR ALOFT IS LIKELY TO PREVENT
THUNDERSTORMS UP TO THAT TIME... BUT LIFTING AND COOLING ALOFT WILL
WEAKEN THE CAP ENOUGH TO ALLOW THUNDERSTORMS TO DEVELOP RAPIDLY NEAR
AND EAST OF THE DRY LINE BY LATE AFTERNOON... PROBABLY AROUND 3 TO 5
PM. STORMS ARE LIKELY TO INTENSIFY RAPIDLY BY EARLY EVENING. WITH
VERY UNSTABLE CONDITIONS... AND STRONG WINDS AT ALL LEVELS AHEAD OF
THE APPROACHING SYSTEM ALOFT... THE ENVIRONMENT WILL SUPPORT
LONG-LIVED SUPERCELLS AND AN ATTENDANT RISK OF EXTREMELY LARGE HAIL
AND DAMAGING WINDS. TORNADOES WILL BE LIKELY WITH THE MOST INTENSE
STORMS... AND THE POTENTIAL WILL EXIST FOR ONE OR MORE LARGE
LONG-TRACK TORNADOES IN THE HIGH RISK AREA.

THE RISK OF SEVERE WEATHER WILL CONTINUE WELL INTO THE NIGHT... BUT
SHOULD SHIFT INTO FAR EASTERN OKLAHOMA BY AROUND MIDNIGHT.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT WEDNESDAY MAY 25.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...100 PERCENT.

OTHER HAZARDOUS WEATHER...
HIGH WINDS...LOW HUMIDITIES AND WARM TEMPERATURES BEHIND THE DRY
LINE WILL LEAD TO EXTREME WILDFIRE DANGER FOR FAR WESTERN OKLAHOMA
AND WESTERN PARTS OF NORTH TEXAS THIS AFTERNOON. A RED FLAG WARNING
IS IN EFFECT. PLEASE REFER TO THE LATEST VERSION OF THIS PRODUCT FOR
MORE INFORMATION.

TODAY WOULD HAVE POTENTIAL TO BE AN ACTIVE SEVERE WEATHER DAY GIVEN
A FAIRLY ROBUST NEGATIVE-TILT UPPER TROUGH ROTATING OUT OF THE BASE
OF THE UPPER LOW OVER CO/WY. MITIGATING FACTOR IS LIKELY TO BE THE
WIDESPREAD ONGOING CONVECTION EARLY THIS MORNING OVER W PARTS OF
OK/TX. CONSIDERABLE UNCERTAINTY AS TO HOW MUCH RECOVERY WILL OCCUR
IN THE WAKE OF THESE STORMS. CURRENT THINKING IS THAT EXISTING
SQUALL LINE/MCS WILL CONTINUE E THROUGH THE MORNING BUT WITH SEVERE
POTENTIAL LIMITED BY THE UNFAVORABLE TIME OF NIGHT/MORNING. THERE
ALSO WILL BE LIMITED POTENTIAL FOR STRONG DESTABILIZATION BEHIND IT.
THUS THERE IS A QUESTION AS TO WHETHER THE ADVANCING DRYLINE/COLD
FRONT WILL SUPPORT ANOTHER ROUND OF STORMS LATER TODAY. STRONG SFC
CONVERGENCE ALONG THE BOUNDARY... AND STRONG DYNAMIC FORCING
ALOFT... MAY LEAD TO ANOTHER SQUALL LINE LATER TODAY WITH LARGE HAIL
AND DAMAGING WINDS THE MAIN CONCERNS. DISCRETE SUPERCELLS WILL BE
POSSIBLE AT LEAST FOR A WHILE... WITH AN ATTENDANT RISK OF GIANT
HAIL AND TORNADOES.

MAIN FOCUS THIS MORNING IS ON THE ONGOING CONVECTION AND THE
POTENTIAL FOR REDEVELOPMENT. AS SUCH WE WILL MAKE ONLY SUPERFICIAL
ADJUSTMENTS TO THE REST OF THE FORECAST. WE MAY HAVE A RELATIVE
BREAK IN CHANCES OF RAIN/STORMS ON SAT AS WE END UP BETWEEN

.DISCUSSION...
WATCHING FOR FOG DEVELOPMENT THIS MORNING OVER CENTRAL OK E OF THE
DRYLINE WHERE DEWPOINT DEPRESSIONS ARE AT OR NEAR ZERO. IT LOOKS
LIKE THERE WILL BE ENOUGH WIND TO KEEP ANY FOG FROM BECOMING A
WIDESPREAD HAZARD... BUT A FEW SPOTS HAVE DROPPED TO 1/4 MILE AT
TIMES. WE PROBABLY CAN HANDLE THIS WITH NOWCASTS AND THE HWO...
BUT THERE IS STILL A CHANCE WE WILL NEED TO POST AN ADVISORY FOR
SOME AREAS BEFORE DAYBREAK.

NEXT ISSUE IS SEVERE STORM POTENTIAL LATER TODAY. DRYLINE SHOULD
MIX E TO NEAR OR E OF I-35 BY MID AFTERNOON. MODELS ARE LIKELY
OVERDOING THE SFC DEWPOINTS IN THE 70S OVER E OK THIS AFTERNOON...
ESPECIALLY WITH THE WEAKENING MCS OVER TX/LA DOING WHAT IT CAN TO
INTERCEPT THE RETURN OF RICHER LOW-LEVEL MOISTURE. BUT MID-UPPER
60S DEWPOINTS STILL WILL YIELD SBCAPES AOA 2000 J/KG... THUS
SUPPORTING A FEW ORGANIZED SEVERE STORMS E OF I-35 BY MID-LATE
AFTERNOON. DEEP LAYER SHEAR MAY END UP STRONGER THAN FRIDAY AS THE
MID-LEVEL FLOW WILL BE MORE VEERED. THERE IS AN APPARENT SHORTWAVE
TROUGH ROTATING AROUND THE UPPER LOW... SEEN ON SATELLITE OVER
CO/NM EARLY THIS MORNING. THIS FEATURE MAY BE THE INSTIGATOR OF
STORM INITIATION AS IT REACHES THE DRYLINE IN E OK LATE TODAY.
GREATER SEVERE RISK APPEARS TO BE E OF OUR CWA THIS
AFTERNOON/EVENING.

DRYLINE WILL RETREAT W/NW AGAIN SATURDAY NIGHT AND MOST LIKELY
WILL BECOME ORIENTED MORE NE-SW FROM NCENTRAL OK INTO OUR TX ZONES
BY SUNDAY. WE THEN WILL BE SET UP FOR ANOTHER POSSIBLE ROUND OF
STRONG/SEVERE STORMS LATE SUNDAY AND SUNDAY NIGHT... MAINLY S AND
E PARTS OF THE AREA PER SWODY2.

THE PLOT THICKENS EARLY NEXT WEEK AS AN EXTENSIVE NEGATIVELY-
TILTED LONGWAVE TROUGH DEVELOPS FROM THE NE PACIFIC SE-WARD ACROSS
THE INTERMOUNTAIN W INTO AZ/NM. THIS IS AN OMINOUS LONGWAVE
PATTERN FOR THE S PLAINS IN LATE SPRING. MODEL CONSENSUS APPEARS
TO SUPPORT ONE SIZEABLE PIECE EJECTING FROM THE SW TROUGH INTO THE
CENTRAL/S PLAINS MONDAY FOLLOWED BY AN EVEN LARGER PIECE TUESDAY.
EITHER OR BOTH DAYS COULD FEATURE ACTIVE AND WIDESPREAD SEVERE
WEATHER IN AND AROUND OK/TX. BUT THE STANDARD DISCLAIMER APPLIES -
CONVECTIVE EVOLUTION ON ANY GIVEN DAY WILL LIKELY AFFECT THE
EVOLUTION OF STORMS ON SUBSEQUENT DAYS IN ONE WAY OR ANOTHER. WE
WILL MAINTAIN 30-50 PCT POPS IN MOST PERIODS FROM MONDAY THROUGH
TUESDAY IN ANTICIPATION OF FAIRLY WIDESPREAD CONVECTION. POPS THEN
ARE TAPERED OFF GOING INTO WEDNESDAY WHEN IT APPEARS COOLER/DRIER
AIR WILL FINALLY OVERSPREAD THE AREA.

MODEL VARIANCE THEN INCREASES SO THE FORECAST FOR LATE NEXT WEEK
IS A LOW-CONFIDENCE ONE. WE WILL KEEP PRECIP OUT OF THE FORECAST THU-
FRIDAY... THINKING EITHER THE UPPER SYSTEM WILL BE DOWNSTREAM OF

.DISCUSSION...
SEVERAL ROUNDS OF ACTIVE CONVECTION EXPECTED NEXT 3 DAYS.
INSTABILITY AND DEEP-LAYER SHEAR TODAY SHOULD BE AT LEAST AS
STRONG AS THEY WERE SATURDAY... SO ANYTHING THAT GOES UP IN THE
WARM SECTOR LATER TODAY WILL PROBABLY BECOME SUPERCELLULAR AND
THUS WILL BE CAPABLE OF ALMOST ANYTHING. DEVELOPMENT MOST LIKELY
TO OCCUR NEAR DRYLINE DURING MID-LATE AFTERNOON... A BIT SOONER
THAN YESTERDAY AND PROBABLY NEAR OR SLIGHTLY SE OF THE I-44
CORRIDOR. NOT SEEING A DISTINCT FEATURE TO INITIATE STORMS
TODAY... AND SO THE COVERAGE MAY BE QUITE LIMITED MUCH LIKE IT WAS
YESTERDAY. AS SUCH WE ARE HOLDING FOR NOW WITH A HIGHER-END SLIGHT
RISK TODAY... BASED ON LIMITED COVERAGE BUT AN ACKNOWLEDGED RISK
OF GIANT HAIL AND PERHAPS 1 OR 2 STRONG TORNADOES GIVEN THE
PROGGED SHEAR/HELICITY.

BEYOND TODAY THE DETAILS OF CONVECTIVE EVOLUTION BECOME MORE
DIFFICULT TO DETERMINE... MAINLY BECAUSE OF THE INEVITIBLE EFFECTS
OF PERIOD-N CONVECTION ON PERIOD N+1. GENERAL TREND IS LIKELY TO
BE FOR INCREASINGLY WIDESPREAD STORMS GOING INTO MON-TUE AS WE
COME UNDER THE EFFECTS OF THE DEVELOPING NEGATIVE-TILT TROUGH FROM
OFF THE PACNW COAST INTO THE INTERMOUNTAINW AND SW CONUS. IMPULSES
RIDING OUT FROM THIS TROUGH LIKELY TO ENHANCE CONVECTIVE POTENTIAL
TONIGHT AND ESPECIALLY MONDAY... THEN THE WHOLE THING COMES OUT
TUE AND TUE NIGHT. THERE ARE LIKELY TO BE ONE OR MORE CONVECTIVE
COMPLEXES/CLUSTERS OVER THE COURSE OF THE NEXT 2-3 DAYS. THESE
COMPLEXTS COULD SUPPRESS OR SHIFT THE SEVERE POTENTIAL IN
SUBSEQUENT PERIODS BY WORKING OVER THE LOW LEVELS... OR THEY COULD
INCREASE THE SEVERE POTENTIAL IN SOME AREAS BY LAYING OUT ONE OR
MORE BOUNDARIES FOR STORMS TO FOCUS ON.

STANDARD INITIALIZATION WAS USED FOR WED AND BEYOND WITH ONLY
MINOR ADJUSTMENTS TO BETTER MATCH SURROUNDING GRIDS. UPPER SYSTEM
SHOULD DO A SWEEP AND CLEAR BY WED NIGHT... LEAVING COOLER AND DRIER
CONDITIONS. GFS IS AN OUTLIER WITH A DIGGING UPPER LOW INTO MO/AR

SOUTH CENTRAL INTO EAST CENTRAL OKLAHOMA. VERY LARGE HAIL WILL BE
COMMON. THE STORMS ARE EXPECTED TO REMAIN SOUTH AND EAST OF
OKLAHOMA CITY. MVFR CEILINGS ARE EXPECTED TONIGHT SOUTH TO NORTH IN

OF DRYLINE WHICH HAS MIXED EASTWARD INTO CENTRAL OK THIS
AFTERNOON. AREA OF CU BEGINNING TO DEVELOP IN CENTRAL OK AND ALSO
IN FAR NCNTRL OK. GIVEN THE AMOUNT OF INSTAB AND FAVORABLE
SHEAR...ANY STORMS THAT DEVELOP COULD RAPIDLY BECOME SEVERE AND WATCH
IS ALREADY IN PLACE FOR THIS AFTN/EVE. ACTIVE WEATHER WILL
CONTINUE THROUGH THE EARLY PART OF THE WEEK WITH THREAT FOR SEVERE
STORMS CONTINUING THROUGH TUESDAY AS UPPER TROUGH OVER THE WESTERN
U.S. TODAY ADVANCES EASTWARD INTO THE PLAINS. ALTHOUGH THREAT FOR
SEVERE STORMS WILL SHIFT EASTWARD ON WEDNESDAY...SOME SHOWERS AND
THUNDERSTORMS MAY LINGER OVER PARTS OF THE AREA AS UPPER LOW MOVES
SOUTHEASTWARD ACROSS KS. DRY WEATHER THEN EXPECTED FOR THE LATTER
PART OF THE WEEK AS THIS SYSTEM EXITS EWD AND THE UPPER RIDGE
BEGINS TO BUILD OVER THE CENTRAL PART OF THE COUNTRY.

MAIN FOCUS IS ON SEVERE WEATHER POTENTIAL NEXT 2 DAYS.

THERE IS GROWING CONCERN THIS MORNING THAT A MORE WIDESPREAD SEVERE
EVENT MAY OCCUR LATER TODAY. THE AREA IS UNDISTURBED BY OVERNIGHT
CONVECTION... AND SKIES ARE MOSTLY CLEAR AT THE MOMENT. DIURNAL
HEATING SHOULD LEAD TO MODERATE TO EXTREME INSTABILITY AGAIN BY
AFTERNOON WITH SBCAPES 3000-5000 J/KG. DEEP-LAYER SHEAR /0-6KM/ IS
FORECAST TO BE STRONGER TODAY OVER THE MOIST SECTOR WITH MAGNITUDES
45-60KT OR SO BY 00Z THIS EVENING... VS 35-45KT SUNDAY EVENING.
SATELLITE LOOP INDICATES AN OMINOUS-LOOKING IMPULSE OVER N MEXICO
MOVING RAPIDLY ENE. THIS FEATURE EXTRAPOLATES TO N TX AREA THIS
AFTERNOON WITH A PROBABLE STEEPENING OF MID-LEVEL LAPSE RATES
WITHIN THE AREA OF DRYING ALOFT. BASED ON 06Z NAM WE WILL NOT HAVE
THE DRYLINE IN THE AREA AS A FOCUS... IT REMAINS NEAR OUR W
BORDER... BUT NAM INDICATES WIDESPREAD CONVECTION BLOWING UP
ACROSS THE ENTIRE MAIN BODY OF OKLAHOMA 18-21Z. THIS MAY BE
CONNECTED TO THE APPROACHING SYSTEM NOW NEAR EL PASO. UNLIKE THE
LAST 2 DAYS WHEN LIMITED AREAL COVERAGE PRECLUDED MORE THAN A
SLIGHT RISK... WE MAY HAVE THE OPPOSITE PROBLEM TODAY WITH STORMS
BECOMING TOO NUMEROUS AND UPDRAFT COMPETITION LIMITING THE CHANCES
OF ANY ONE STORM TO MAINTAIN DOMINANCE. BUT WITH ALL ELSE
SUPPORTING MORE WIDESPREAD SEVERE STORMS TODAY... WE ARE DISCUSSING
THE SITUATION FURTHER WITH SPC AND WILL GO TO A MODERATE RISK IN
THE UPCOMING HWO. WE PLAN TO DO ANOTHER 18Z SOUNDING TODAY.

TUESDAY HAS THE POTENTIAL TO BE EVEN WORSE IN TERMS OF WIDESPREAD
AND POSSIBLY SIGNIFICANT SEVERE WEATHER. MUCH WILL DEPEND ON HOW
STORMS EVOLVE TODAY AND TONIGHT. AXIS OF VERY POTENT NEGATIVE-TILT
UPPER TROUGH IS FORECAST TO MOVE INTO NM EARLY TUE AND DRIVE E INTO
W TX BY 18Z. EFFECTS OF THIS SYSTEM MAY ARRIVE RELATIVELY EARLY IN
OK ON TUE AND LEAD TO AN EARLY START TO THE CONVECTION. IF CAP HOLDS
OFF INITIATION UNTIL LATER IN THE DAY WHEN INSTABILITY WILL LIKELY
GO FROM STRONG TO EXTREME.. WE COULD BE LOOKING AT A SIGNIFICANT
SEVERE WEATHER OUTBREAK PER SWODY2.

UNSEASONABLY STRONG WINDS FOR LATE MAY COULD DEVELOP TUESDAY AND
WEDNESDAY IN ASSOCIATION WITH THE INTENSE 992-ISH SURFACE LOW -
ALSO UNSEASONABLY STRONG FOR LATE MAY. STRONGEST WINDS LIKELY TO
BE SOUTHWESTERLY OUT W TUESDAY AFTERNOON BEHIND THE DRY LINE...
AND FROM THE NW ON WEDNESDAY ON THE BACK SIDE OF THE LOW. GFS-MOS
GUIDANCE GIVES US 30-35 KT OVER W OK... AND 35-45 KT OVER W KS AND
NW TX. THIS IS VERY REMARKABLE FOR THIS LATE IN THE SPRING. WE
WILL NOT GO QUITE THAT STRONG... BUT VERY WELL MAY BE LOOKING AT
WIND ADVISORIES ON EITHER OR BOTH DAYS.

COOLER ALL AREAS WED AS SYSTEM WINDS UP AND BECOMES VERTICALLY
STACKED OVER E KS. MAY BE SOME WRAPAROUND SHOWERS OR SOME RELATIVELY
WEAK COLD-POOL CONVECTION ON WEDNESDAY ACROSS MAINLY N OK.

EXTENDED GRIDS BASED ON STANDARD INITIALIZATION WITH MINOR RETOOLING
TO MATCH UP BETTER WITH NEIGHBORS. KEEPING IT DRY FOR NOW... BUT
THERE ARE INCREASING INDICATIONS THAT THE RIDGING UPSTREAM OF THE
TUE-WED SYSTEM WILL BREAK DOWN BY THE END OF THE WEEK. THIS COULD
PLACE US BACK INTO AN ACTIVE PATTERN BY MEMORIAL DAY WEEKEND. POPS
ALMOST CERTAINLY WILL NEED TO BE RAISED AT SOME POINT... BUT THERE
IS PRESENTLY TOO MUCH VARIANCE BETWEEN THE GFS AND THE ECMWF TO EVEN
BEGIN TO SAY WHEN AND WHERE THE HIGHER CHANCES WILL BE.

.DISCUSSION...
VERY ACTIVE WEATHER DAY WILL DEVELOP TODAY... BOTH WITH THE HIGH
RISK OF SEVERE STORMS EAST OF THE DRYLINE AND FIRE WEATHER
POTENTIAL WEST OF THE DRYLINE.

STRONG UPPER TROF OVER UTAH AND ARIZONA IS BEGINNING ITS MOVE
TOWARD THE PLAINS THIS MORNING. ALL MODELS INDICATE THIS TO COME
OUT AS A NEGATIVE TILT TROUGH INTO THE SOUTHERN HIGH PLAINS BY
THIS EVENING... ACCOMPANIED BY A 70-80 KNOT 500 MB JET NOSING INTO
WESTERN NORTH TEXAS AND A 110 KNOT 300 MB JET INTO THE HIGH PLAINS
OF TEXAS. WITH THE APPROACH OF THE UPPER STORM SYSTEM... SURFACE
CYCLOGENESIS DEEPENS THE SURFACE LOW TO ABOUT 992 MB ACROSS
NORTHWEST OKLAHOMA OR SOUTHWESTERN KANSAS. IT REMAINS TO BE SEEN
HOW FAR EAST THE DRYLINE WILL MOVE IN TIME FOR CONVECTIVE
DEVELOPMENT THIS AFTERNOON... BUT MOST LIKELY TO NEAR OR JUST WEST
OF THE US-81 CORRIDOR. THIS PLACES IN MUCH OF THE EASTERN HALF OF
THE AREA /INCLUDING THE OKLAHOMA CITY METRO AREA/ AT HIGH RISK FOR
SEVERE THUNDERSTORMS WITH VERY HIGH INSTABILITY AND WIND SHEAR
EXPECTED. AGREE WITH SPC ON THE HIGH RISK OF SEVERE STORMS. SEE
SPC DAY 1 OUTLOOK AND OUR HAZARDOUS WEATHER OUTLOOK FOR MORE
DETAILS.

TO THE WEST OF THE DRYLINE... VERY DRY AIR AND GUSTY WINDS WILL
MOVE INTO WESTERN OKLAHOMA AND WESTERN NORTH TEXAS RAISING FIRE
WEATHER CONCERNS. FIRE WEATHER WATCH WILL BE UPGRADED TO RED FLAG
WARNING... AND EXTENDED SOUTH TO INCLUDE PORTIONS OF SOUTHWEST
OKLAHOMA AND OUR WESTERN NORTH TEXAS ZONES EAST TO WILBARGER AND
BAYLOR. INFORMATION FROM THE STATE FORESTRY SERVICE INDICATE THAT
SUFFICIENT GREENING MAY HAVE DEVELOPED IN SOUTHWESTERN OKLAHOMA
THAT RED FLAG MAY NOT BE NECESSARY THERE... BUT HAVE INCLUDED FOR
CONTINUITY AND THE EXTREMELY LOW RH EXPECTED IN THIS REGION.

STORM SYSTEM IS SLOW TO MOVE OUT SO SOME PRECIPITATION CHANCES
CONTINUE INTO WEDNESDAY AND PERHAPS WEDNESDAY EVENING ALTHOUGH THE
BEST LOW-LEVEL MOISTURE AND SEVERE WEATHER RISK WILL HAVE SHIFTED
EAST OF THE AREA. STRONG WINDS ARE ALSO LIKELY ON WEDNESDAY AND A
WIND ADVISORY MAY BE NEEDED... BUT WE WILL NOT ISSUE ANY HEADLINES
WITH THIS PACKAGE WITH THE POTENTIALLY HIGHER IMPACT WEATHER TODAY
AND TONIGHT.

ACROSS PORTIONS OF SOUTH CENTRAL... CENTRAL AND NORTHWEST OKLAHOMA
MAY AFFECT VARIOUS TAF SITES THIS MORNING. A DRYLINE WILL MOVE
INTO WESTERN OKLAHOMA SHIFTING WINDS TO A SOUTHWESTERLY TO
WESTERLY WIND THIS MORNING. THERE MAY BE BLOWING DUST IN FAR
WESTERN OKLAHOMA AND ALTHOUGH NOT HIGH ENOUGH LIKELIHOOD TO
INCLUDE IN THE TAFS... COULD POTENTIALLY AFFECT SOME OF THE
WESTERN TAF SITES. OF MORE CONCERN WILL BE THE POTENTIAL SEVERE

.DISCUSSION...
STORM INITIATION HAS OCCURRED IN WESTERN OK...AHEAD OF A DRYLINE
WHERE THE MID LEVEL CAP IS WEAKEST. WE STILL EXPECT A BROKEN LINE
OF STRONG TO SEVERE THUNDERSTORMS TO FORM ALONG THE DRYLINE...THEN
MOVE EAST. A TORNADO WATCH HAS ALREADY BEEN ISSUED FOR THE OUN CWA
EAST OF THE DRYLINE...AND IS VALID UNTIL 10 PM. THE SEVERE WEATHER
RISK IS EXPECTED TO DECLINE IN THE OUN CWA BY MIDNIGHT.

STRONG SOUTHWEST WINDS AND VERY DRY AIR SHOULD CONTINUE TO AFFECT
FAR WESTERN PORTIONS OF THE CWA INTO THIS EVENING...SO THE RED FLAG
WARNING WILL BE LEFT AS IS. FOR WEDNESDAY...THOUGH TEMPERATURES WILL
BE COOLER... MODERATE NORTHWEST WINDS AND DRY AIR MAY RESULT IN
MEETING RED FLAG CRITERIA AGAIN IN PORTIONS OF WESTERN NORTH TEXAS.
A RED FLAG WATCH WILL BE ISSUED FOR THESE AREAS WEDNESDAY AFTERNOON.
THOUGH IT SHOULD BE COOLER IN OK...MODERATE NORTHWEST WINDS WILL
ELEVATE WILDFIRE CONCERNS IN FAR WESTERN OK AS WELL.

THUNDERSTORMS ARE POSSIBLE AGAIN ON WEDNESDAY ESPECIALLY IN NORTHERN
OKLAHOMA... BUT SEVERE THUNDERSTORMS ARE UNLIKELY. RELATIVELY COOL
WEATHER IS EXPECTED ON WEDNESDAY AND THURSDAY...WITH THURSDAY
EXPECTED TO BE DRY.

NO CHANGES TO THE FORECAST HAVE BEEN MADE FROM FRIDAY ONWARD.
