MD 2222 CONCERNING SEVERE THUNDERSTORM WATCH 700… FOR WEST TEXAS

Mesoscale Discussion 2222 NWS Storm Prediction Center Norman OK 0508 PM CDT Tue Oct 03 2023 Areas affected...West Texas Concerning...Severe Thunderstorm Watch 700... Valid 032208Z - 032345Z The severe weather threat for Severe Thunderstorm Watch 700 continues. SUMMARY...Isolated severe thunderstorms will persist across ww700 this evening. New severe thunderstorm watch may be issued across the TX South Plains. DISCUSSION...Isolated severe thunderstorms have developed over western portions of ww700 early this evening. This activity is evolving within modest southwesterly mid-level flow along an axis of instability characterized by MLCAPE values on the order of 2000 J/kg. Weak height falls are noted ahead of the western US trough and this may encourage some longevity of convection this evening, especially as 850mb inflow is expected to increase later this evening into this region. Over the last hour or so, new updrafts are forming across northern portions of ww700, and thunderstorms may begin to spread north of the watch. If this activity continues to increase in coverage/intensity, new ww may be issued over the TX South Plains. ..Darrow.. 10/03/2023 ...Please see www.spc.noaa.gov for graphic product...
