ZCZC SPCSWOMCD ALL ACUS11 KWNS 291509 SPC MCD 291509 TXZ000-291645- Mesoscale Discussion 0799 NWS Storm Prediction Center Norman OK 1009 AM CDT Sat May 29 2021 Areas affected...South TX Concerning...Severe potential...Watch unlikely Valid 291509Z - 291645Z Probability of Watch Issuance...20 percent SUMMARY...An increase in thunderstorm intensity is possible over the next few hours with a risk for isolated strong/severe wind gusts. A watch is not currently anticipated. DISCUSSION...Latest KBRO reflectivity trends show thunderstorms associated with a long-lived MCS continuing to move southeast, with some intermittent increase in updraft intensity. Despite substantial MCS-associated high-level clouds extending downstream, the presence of mid-upper 70s dew points has contributed to strong surface-based instability. Further, 25-30 kts of mid-level flow will provide a favorable environment for continued re-intensification of individual storms and perhaps some increase in organization of the convective complex, which would increase the risk for more concentrated damaging wind potential as the system approaches the coast. A watch is not anticipated, however trends will continue to be monitored. ..Bunting/Hart.. 05/29/2021 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CRP...BRO...
