Thunderstorms with hail and isolated severe gusts will be possible on Sunday from parts of the lower to mid Missouri Valley into the central and northern Plains. ...Lower to Mid Missouri Valley/Central and Northern Plains... A mid-level shortwave trough will move northward across the north-central U.S. on Sunday, as flow in its wake remains from the west-southwest. At the surface, a mesolow is forecast to develop over southern South Dakota as a dryline sharpens over western Kansas and western Nebraska. A broad moist sector will be in place from the dryline eastward to near the Mississippi River. Across much of this moist airmass, moderate to strong instability is expected to develop by afternoon. Thunderstorms will be possible along low-level convergence zones that setup in the afternoon. However, convective coverage should remain isolated due to rising mid-level heights associated with a ridge aloft. In spite of the weak forcing, the environment will support an isolated severe threat with cells that can initiate and persist. A few severe wind gusts and hail will be the primary threats. ..Broyles.. 05/29/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
