MD 0948 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF SOUTHWESTERN TEXAS
Mesoscale Discussion 0948 NWS Storm Prediction Center Norman OK 0450 PM CDT Wed Jun 07 2023 Areas affected...portions of southwestern Texas Concerning...Severe potential...Watch unlikely Valid 072150Z - 072315Z Probability of Watch Issuance...20 percent SUMMARY...Occasional instances of severe hail and wind are possible with the stronger storms through the remainder of the afternoon into early evening. The severe threat is expected to remain isolated enough such that a WW issuance appears unlikely. DISCUSSION...Multiple multicell clusters and supercells have developed over the past hour across the TX Trans Pecos region. A mid-level shortwave trough and associated 7-8 C/km mid-level lapse rates continue to overspread upper 50s/low 60s F dewpoints, resulting in increasing buoyancy (1000+ J/kg MLCAPE) and deep-layer ascent to support the continued intensification of storms. Modest mid-level flow is also overspreading southwestern Texas, resulting in lengthy hodographs and accompanying 35-45 kts of effective bulk shear. Large hail may accompany the stronger storms, with severe gusts also possible (given the well-mixed boundary layer and 9+ C/km low-level lapse rates). However, the overall severe threat should remain relatively isolated and a WW issuance is not currently expected. ..Squitieri/Hart.. 06/07/2023 ...Please see www.spc.noaa.gov for graphic product...
