A few strong to locally severe storms are possible across the central U.S. on Sunday, from the Dakotas into the Ozarks, and across southwest Texas. ...Synopsis... A weak negatively tilted shortwave trough will move northward across the northern Rockies and Plains on Sunday, with cool midlevel temperatures. Mid to high level winds of 30 to 60 kt will stretch from CO into KS and NE, behind the upper wave. This will also result in midlevel drying across the central Plains. A surface trough is generally forecast to exist along the length of the High Plains, with low pressure centers over SD and western TX during the afternoon. High pressure will exist from the Great Lakes to the East Coast with an upper trough over the Northeast, and southerly surface winds will maintain low-level moisture west of this surface high from the lower MS Valley northwestward across the MO Valley. ...Dakotas southeastward into AR... Storms may be ongoing over southern MO or northern AR Sunday morning, with southwest low-level flow/warm advection supporting continued unstable inflow. Conditionally, an MCS is possible, with potential to persist southeastward into AR and perhaps even MS later in the day. This is a bit uncertain, but locally severe gusts would be possible. Farther north, scattered daytime storms are likely beneath the upper wave from central SD into ND. Temperatures aloft will be cool and may support hail despite weak shear. To the south, diurnal storms appear most likely from eastern KS into western MO late in the afternoon and into the evening as moderate to strong instability develops. Some of this may depend on how much early day activity occurs, and if any outflow boundaries exist. Conditionally, a couple supercells cannot be ruled out with hail and brief tornado risk. ...OK into western TX... Strong heating will occur along a dryline extending roughly from north-central OK into northwest TX. Weak surface convergence, 60s F dewpoints and a narrow corridor of weak inhibition may yield isolated thunderstorms by late afternoon. These storms would likely be brief, but could yield locally strong gusts or marginal hail. Farther south, storm coverage will be greater into southwest TX, where southeast surface winds will maintain moisture flux into the area during the afternoon. Scattered storms are likely here, with locally strong outflow winds and perhaps marginal hail. ..Jewell.. 05/30/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
