Valid 252315Z - 260045Z The severe weather threat for Tornado and Severe Thunderstorm Watches 392, 393 continues. SUMMARY...The threat for damaging wind gusts is increasing across portions of western Oklahoma. DISCUSSION...Several previously discrete supercells have begun to cluster/grow upscale across the northeastern Texas Panhandle and far northwestern Oklahoma over the past 30-60 minutes. With dewpoint depressions of 20-25+ F favoring continued cold pool development and consolidation, expectation is for this activity to continue to consolidate into a forward-propagating cluster as it progresses east-southeastward into western Oklahoma. Moderate to strong instability (2000-3000+ J/kg MLCAPE) and around 40 kts of effective shear will favor a continued severe threat and an attendant increase in the threat for a swath of damaging wind gusts (some 75+ mph). Occasional large hail and perhaps a brief tornado will also remain possible with any stronger embedded cores/supercell structures. ..Chalmers.. 06/25/2026 ...Please see www.spc.noaa.gov for graphic product...
