Mesoscale Discussion 1085 NWS Storm Prediction Center Norman OK 0638 PM CDT Thu May 30 2024 Areas affected...The Permian Basin and Trans-Pecos Concerning...Tornado Watch 354... Valid 302338Z - 310115Z The severe weather threat for Tornado Watch 354 continues. SUMMARY...A tornado, very large hail, and severe damaging wind threat continues across the tornado watch. DISCUSSION...Two confirmed tornadoes were recently reported very close to MAF and briefly Denver City, in addition to very large hail. The supercell near MAF continues to interact with the same outflow boundary, and remains in a favorable environment for additional tornadogensis cycles. The KMAF VAD indicated 0-1 km SRH around 250-350 m2/s2 when the tornado occurred, and recent mesoanalysis suggests a broad area within southeasterly surface flow just behind the modified outflow boundary of 150-200 m2/s2 0-1 km SRH. In addition, steep mid-level lapse rates are contributing large CAPE within the hail growth zone as depicted in local RAP soundings. Increasing low-level shear and moisture advection will continue through the evening hours as a LLJ slowly intensifies. A discrete storm mode is expected to continue (deep layer effective shear 55-60 kt normal to forcing) before mergers occur late this evening. ..Barnes.. 05/30/2024 ...Please see www.spc.noaa.gov for graphic product...
