ZCZC SPCSWOMCD ALL ACUS11 KWNS 260436 SPC MCD 260436 OKZ000-TXZ000-260600- Mesoscale Discussion 1106 NWS Storm Prediction Center Norman OK 1136 PM CDT Fri Jun 25 2021 Areas affected...Texas Panhandle into western Oklahoma Concerning...Severe Thunderstorm Watch 318... Valid 260436Z - 260600Z The severe weather threat for Severe Thunderstorm Watch 318 continues. SUMMARY...Isolated hail/wind remain possible with thunderstorms into the early-morning hours. DISCUSSION...Strong convection has struggled to spread appreciably east across ww318 before gradually weakening. This is possibly due to some remaining inhibition across central OK. Thunderstorms have repeatedly developed upstream where lapse rates are steepest across the High Plains. Recently, convection has tended to focus along/behind the cold front as it drops south across the Panhandle. These trends may continue for some time as greater reservoir of buoyancy currently extends from the TX South Plains into extreme southwestern OK. With southerly 1km AGL flow into this activity, new updrafts remain likely across the southern TX Panhandle. With time the front should sag into western OK and this elongated corridor of convection should progress across much of the western portions of ww318, but not before the watch expires. ..Darrow.. 06/26/2021 ...Please see www.spc.noaa.gov for graphic product...
