243 ACUS11 KWNS 292236 SWOMCD SPC MCD 292236 NDZ000-SDZ000-MTZ000-WYZ000-300000- Mesoscale Discussion 1070 NWS Storm Prediction Center Norman OK 0536 PM CDT Wed May 29 2024 Areas affected...Northern High Plains Concerning...Severe Thunderstorm Watch 349... Valid 292236Z - 300000Z The severe weather threat for Severe Thunderstorm Watch 349 continues. SUMMARY...Scattered strong/severe thunderstorms will shift east this evening. DISCUSSION...Weak mid-level height falls are beginning to suppress the northern Plains ridge early this evening. Scattered convection that evolved over northeast WY has progressed downstream into the primary instability axis characterized by MLCAPE on the order of 1500 J/kg. This activity should continue advancing east this evening as LLJ is expected to increase markedly after sunset in response to the approaching upper trough. Latest radar data suggests many updrafts are generating hail, the most robust updrafts may be producing hail in excess of 1.5 inches. Gusty winds may also accompany this activity as it advances downstream. ..Darrow.. 05/29/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BIS...UNR...CYS...BYZ...GGW...RIW...
