Mesoscale Discussion 0940 NWS Storm Prediction Center Norman OK 0539 PM CDT Fri May 24 2024 Areas affected...Eastern Oklahoma...Western Arkansas...Central and Northeast Texas Concerning...Severe Thunderstorm Watch 303... Valid 242239Z - 250045Z The severe weather threat for Severe Thunderstorm Watch 303 continues. SUMMARY...A threat for large hail and wind damage is expected to increase in coverage over the next couple of hours from northeast Texas into southeast Oklahoma and western Arkansas. DISCUSSION...The latest hi-resolution radar imagery from Fort Worth shows scattered strong to severe thunderstorms located in and around the Dallas/Fort Worth Metro extending northward into southern Oklahoma. Short-term model forecasts suggest that convective coverage will increase, as the complex moves northeastward across western parts of the Ark-La-Tex early this evening. Relatively straight hodographs will be favorable for storm splits. The airmass is extremely unstable with surface dewpoints in the mid to upper 70s F, and MLCAPE estimated by the RAP in the 4500 to 6000 J/kg range. In addition, the latest WSR-88D VWP at Fort Worth has 0-6 km shear near 50 knots. This, combined with 700-500 mb lapse rates near 7.5 C/km, estimated by the RAP, will be favorable for supercells with large hail. Hailstones greater than 2 inches in diameter will be possible with the strongest of storms. Wind damage will also be likely with supercells, and organized intense multicells. ..Broyles.. 05/24/2024 ...Please see www.spc.noaa.gov for graphic product...
