Mesoscale Discussion 1071 NWS Storm Prediction Center Norman OK 0555 PM CDT Wed May 29 2024 Areas affected...The High Plains of Colorado and the Nebraska Panhandle Concerning...Severe Thunderstorm Watch 350... Valid 292255Z - 300100Z The severe weather threat for Severe Thunderstorm Watch 350 continues. SUMMARY...Scattered strong to severe thunderstorms will continue to pose a threat of severe damaging wind gusts, marginally severe hail, and possibly a land spout or two. DISCUSSION...A few clusters of robust updrafts continue to slowly progress eastward off the higher terrain of the NE Panhandle and eastern CO plains. These thunderstorms developed within a lee surface trough/dryline, within an environment characterized by very steep mid and low-level lapse rates, relatively weak deep layer shear, and enhanced surface vorticity. The latter, and localized pockets of enhanced stretching, will continue to support non-zero probabilities for landspouts. In addition, as the evening progresses, continued cell mergers combined with inverted V soundings/large downdraft CAPE could promote severe wind gusts via wet downbursts. Before then, isolated hail stones up to 1-1.75" in diameter will remain possible. ..Barnes.. 05/29/2024 ...Please see www.spc.noaa.gov for graphic product...
