MD 0871 CONCERNING SEVERE THUNDERSTORM WATCH 245... FOR PARTS OF THE LOWER/MIDDLE TEXAS COAST AND VICINITY Mesoscale Discussion 0871 NWS Storm Prediction Center Norman OK 0123 AM CDT Wed May 27 2026 Areas affected...Parts of the Lower/Middle Texas Coast and vicinity Concerning...Severe Thunderstorm Watch 245... Valid 270623Z - 270800Z The severe weather threat for Severe Thunderstorm Watch 245 continues. SUMMARY...A locally favorable corridor for severe wind gusts and large hail is evident over parts of the Lower/Middle TX Coast and vicinity during the next hour or so. DISCUSSION...Along the southern end of an eastward-moving MCS approaching the Middle TX Coast, a somewhat separated cluster of thunderstorms is tracking eastward at around 40 kt toward Corpus Christi and vicinity. Around 40 kt of deep-layer shear oriented perpendicular to the gust front of this upscale-growing cluster and moist/moderately unstable surface-based inflow (sampled by the 00Z CRP sounding) will favor a corridor of severe wind gusts (around 60-70 mph) and possibly large hail as it moves toward the coast over the next hour or so. ..Weinman.. 05/27/2026 ...Please see www.spc.noaa.gov for graphic product...
