Tropical Weather Moving Closer to Texas and Florida

Harvey's remnant is forecast to regain tropical cyclone strength in the next day or two. Once Harvey starts impacting the Texas coast, up to 10 inches of rain will be possible over the next week. Another disturbance on the southern tip of Florida is not expected to strengthen, but it's slow movement could add up to 7 inches of rain over the next week. Heavy rain may produce flash flooding.

A front will stall to our south Wednesday night and Thursday morning. We will continue to have chances of showers and thunderstorms across all but the northeastern parts of North Texas. In addition to cloud to ground lighting, some storms may produce locally heavy rain.
Here's a look at the forecast for the weekend and early next week! Regardless of Harvey's track this weekend, the main focus for our area should be the potential for very heavy rain and possibly some flooding across Central Texas. Stay tuned as we refine the details in the forecast!

North Texas Severe Weather April 23, 2008
Erath-Palo Pinto and Tarrant-Johnson Counties

During the late afternoon hours on Wednesday, April 23, 2008, supercell thunderstorms spread from west Texas into parts of north Texas. Additional thunderstorms developed through the evening hours as the complex of thunderstorms moved east. Reports of tornadoes, very large hail, damaging straight-line winds, and flash flooding accompanied the thunderstorms.  (Read the Local Storm Report Summary)

The WSR-88D radar images below show a supercell thunderstorm near the Erath - Palo Pinto County line at 647 pm CDT. The bright red and pink colors in the radar reflectivity represent values up to 70 dBZ that were caused by very large hailstones. Also note the distinct hook echo on the southern part of the storm straight west of Lipan. The Doppler Velocity image, also taken at 647 pm CDT, shows a large, well-defined counterclockwise circulation pattern across extreme northern Erath County. The red colors in the storm-relative mean radial velocity image indicate winds blowing AWAY from the radar located at KFWS (Fort Worth Spinks airport); the green colors represent winds blowing toward the radar (or from west to east). This supercell thunderstorm prompted the issuance of Tornado Warnings across this area Wednesday evening. This statement gives a brief summary of the known tornadoes that occurred in this area.

These two WSR-88D images were taken at a radar elevation angle of 1.5 degrees at 832 pm CDT on 4/23/08. Intense thunderstorms were moving
across Johnson and southwest Tarrant County. The pattern in the red colors (50+ dBZ) resembles an arc shape or "bow", indicating that very strong low level winds were associated with the line of storms across this area. The mean radial velocity image shows a distinct transition area where outbound (relative to the KFWS radar site which is between Crowley and Rendon) velocities are located next to inbound velocities along a radar radial. This transition zone, which represents a region of intense horizontal wind shear, is best defined on the velocity image from the southwest tip of Tarrant County eastward to between Joshua and Burleson. This thunderstorm moved northeast into Tarrant County and was responsible for producing a tornado near Crowley. The results of the damage survey are available.
