Valid 232331Z - 240030Z The severe weather threat for Severe Thunderstorm Watch 383 continues. SUMMARY...Severe wind and hail (including 2+ inch diameter and 75+ mph gusts) will remain possible with the stronger, longer-lived storms over the next few hours. DISCUSSION...Multiple splitting and right-moving supercells have developed along a convective outflow boundary across the TX Panhandle over the past couple of hours. These storms have been accompanied by up to baseball sized hail per reports and MRMS mosaic MESH data. With over 3000 J/kg MLCAPE and 60+ kts of effective bulk shear present, supercells that remain discrete should continue to produce severe hail (some stones exceeding 2 inches in diameter) over the next few hours. A few severe gusts may also occur, especially where cold-pool mergers may take place. ..Squitieri.. 06/23/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LUB...AMA...
