Severe thunderstorms possible over the upper Midwest and Great Lakes, Heavy Rain and Flooding Possible over the Southwest U.S.

Severe thunderstorms will be possible over portions of the upper Midwest and Great Lakes Tuesday, Wednesday, and Thursday. Damaging winds, large hail, and heavy rainfall possible. Over the Desert Southwest and portions of the Rockies, Monsoonal moisture will lead to locally heavy rainfall and the threat for flash flooding into midweek. Read More >

A Heat Advisory is in effect along and north of a line from Mineral Wells to Cleburne to Ennis to Kaufman from 12 PM Tuesday through 8 PM Wednesday. Highs temperatures will be in the upper 90s to around 100 degrees. When you factor in the humidity, it will feel like it is 100 degrees or higher. Most locations in the Heat Advisory will have maximum heat index values of 105 to 109 degrees.
After a day of relief on Monday, the heat returns Tuesday! High temperatures will be in the upper 90s to near 100 in most areas across North and Central Texas. Heat index values will be in the 99 to 109 range, resulting in a Heat Advisory beginning at noon and extending until Wednesday evening for some areas. Remember to stay hydrated, avoid strenuous activity, and never leave pets or children unattended!
It is July in Texas and it's hot. So you're probably thinking why is the National Weather Service telling us about the heat? Well, it's simple: heat kills. Know the signs of heat exhaustion versus heat stroke. Faint or dizzy with excessive sweating, that's heat exhaustion. Get to a cooler place and drink water. What if you or someone you know, is in the heat and suddenly stop sweating, get a throbbing headache and/or nausea? Well, these are signs of a Heat Stroke and this is an emergency situation. Your body is no longer able to cool off and if you don't get immediate care---it can be potentially fatal. If you're suffering from Heat Stroke, you should call 9-1-1 and then immediately take action to cool down. as you wait for help to arrive.

Below are some images from our storm surveys of wind and tornado damage.

The radar images come in pairs:

  • The left image is the basic reflectivity image indicating the areas of precipitation. Light precipitation is indicated by the green colors, moderate precipitation by the yellows and oranges, with heavy precipitation indicated by the red shades.
  • The right image is called Storm Relative Velocity (SRM). It is a picture of the flow of wind around storms. However, the radar can only see wind's motion either directly toward or away from the radar, yet it gives us the ability to locate opposing wind flow and helps identify tornadoes. In the SRM image, green shades represent wind motion directly toward the radar. Red shades indicate motion directly away from the radar. It is critical to know the location of the radar in the SRM image to ensure if the indicated circulation is cyclonic (indicating possible tornado) or anti-cyclonic (not a tornado except in rare instances). The yellow circle on the SRM image indicated the location of the tornado.

This tornado damaged a few houses in the Coryell City area along CR 273 and CR 262. The heaviest damage was near CR 273, where two houses lost most of their roofs. Several barns, storage sheds, and farm machinery was damaged as well. The debris field extended to the north and northwest, where several power poles were broken. The tornado continued over ranch land in Coryell County before dissipating near Mosheim in Bosque County.

 

Clifton, Bosque County

Confirmed tornado: EF-1 (90-95 mph)

Radar images from the NWS radar in Fort worth at 6:03 pm CST. The radar is located at the top of the image. In the reflectivity image the surface circulation was not well defined but in the SRM image the two opposing wind flows were evident.

The tornado began on the south side of Clifton, just off of 23rd Street, where several trees were uprooted and several homes suffered roof damage. This tornado produced a narrow path of damage to the north side of town, either roof damage from the tornado or from tree or other debris hitting the houses.

Confirmed tornado: EF-1 (90-95 mph)

Radar images from the NWS radar in Fort Worth at 6:48 pm CST. The radar is located at the top of the image. In the reflectivity image the tornado is on the leading edge of the parent thunderstorm. The SRM image clearly indicated rotation.

The tornado started on the far eastern side of Bosque County, near Laguna Park. The tornado then crossed over Lake Whitney before damaging several homes on the east side of the lake in far western Hill County. The heaviest damage was concentrated in Hill County, along both sides of FM 1713 near CR 1236. Numerous homes were damaged by the tornado, as were a church and a marina.

Radar images from the NWS radar in Fort Worth at 8:11 pm CST (Johnson County) and at 8:20 pm CST (Tarrant County). The radar is located near the left edge of the images.

A weak tornado occurred in the far northeastern corner of Johnson County, beginning just west of Lone Star Road and Main Street in far southern Mansfield. The tornado damaged metal buildings on the south side of Lone Star Road as well as one house. The storm then moved northeast across Highway 287, damaging one barn just over the county line off of Mitchell Road.

 

Grand Prairie, Tarrant/Dallas County

Confirmed tornado: EF-0 (80-85 mph)

Radar images from the NWS radar in Fort Worth at 8:40 pm CST. The radar is located beyond the bottom left corner of the images.

Weather equipment at Grand Prairie Municipal Airport (Tarrant County) measured a wind gust of 63 mph. Based on wind damage surveyed at the airport, the peak winds were estimated at 80 mph.

Storm spotters and airport observers reported a tornado near the airport. Damage to homes east of the airport (in Dallas County) was indicative of EF-0 tornado damage, estimated at 65 to 85 mph.

Confirmed tornado? No

Another example of why we have storm spotters. The reflectivity image indicated a "hook" shape, which can indicate a tornado. However, the SRM image did not indicate rotation.

At 9:20 pm CST, the two "hooks" were on the leading edge of straight line winds associated with the line of thunderstorms. Damage occurred along 635 in north Dallas.
