Isolated severe thunderstorms are possible from Kansas into Minnesota and across portions of the Southeast today into tonight, accompanied by at least some risk for severe weather. ...Central Great Plains into MN... An upper trough over the Upper Midwest will move east into the Great Lakes with zonal flow extending east from the northern Rockies into the north-central states. The 12 UTC raob at Norman, OK sampled only a modestly moist airmass (10.5 g/kg lowest 100-mb mean mixing ratio) with surface stations farther north in the central Plains observing lower surface dewpoints than in OK. The moisture quality and weak forcing regime will probably limit overall storm coverage/intensity. However, isolated to widely scattered storms are forecast near a weak surface trough later this afternoon and evening. Vertical wind shear will support organized storms including the possibility for a few supercells, mainly from NE into MN. Large hail appears to be the primary hazard but severe gusts are also possible. Farther south into KS where deep-layer shear is forecast to be weaker, steep lapse rates will yield potential for isolated severe gusts with the stronger evaporatively cooled downdrafts. ...Southeast... Water-vapor imagery this morning shows upper troughing extending from the Upper Midwest southward into the northwest Gulf Coast. Downstream of this eastward-migrating upper feature, an MCV over southern AL will move northeast into GA later today and serve as the primary impetus for severe-weather potential. The WSR-88D VAD in Mobile, AL (KMOB) this morning sampled a belt of stronger 3-6 km flow (30-40 kt) associated with the disturbance. Seasonably rich low-level moisture and heating ahead of the ongoing convective band/cloud shield will result in moderate buoyancy by midday. This buoyancy and forcing for ascent will promote scattered thunderstorms developing in the form of linear clusters. The stronger water-loaded downdrafts will be capable of localized 50-65 mph gusts and isolated wind damage through the early evening before this activity subsides. ..Smith/Weinman.. 05/24/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
