ZCZC SPCSWOMCD ALL ACUS11 KWNS 160441 SPC MCD 160441 TXZ000-160645- Mesoscale Discussion 0265 NWS Storm Prediction Center Norman OK 1141 PM CDT Fri Mar 15 2024 Areas affected...South Texas Concerning...Severe Thunderstorm Watch 55... Valid 160441Z - 160645Z The severe weather threat for Severe Thunderstorm Watch 55 continues. SUMMARY...A threat for large hail and wind damage is likely to continue for a few more hours across south Texas. DISCUSSION...The latest hi-resolution radar from Corpus Christi shows a large supercell to the southeast of Laredo. This storm is located along the northern edge of a pocket of moderate to strong instability, where the RAP has MLCAPE in the 2000 to 3000 J/kg range. The storm appears to be supported by a large-scale ascent associated with a subtle shortwave trough evident on water vapor imagery. Lift associated with the trough, steep mid-level lapse rates, and moderate deep-layer shear will likely continue to be favorable for a severe threat as this storm moves eastward across south Texas, and with additional cells that develop within the small cluster. A potential for large hail and wind damage is expected to persist for a few more hours. ..Broyles.. 03/16/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CRP...BRO...
