Isolated strong to severe thunderstorms are possible across portions of the upper Mississippi River Valley to Lower Michigan late Monday night into early Tuesday morning. ...Discussion... A progressive low-amplitude shortwave trough will move across the northern Rockies and into the northern Plains Monday into Tuesday morning, with cooling aloft spreading into the upper MS Valley/Great Lakes late. Ahead of this feature, low pressure will develop over the northern Plains during the day, translating east across IA and toward WI overnight and into Tuesday morning. East of the developing low, a quasi-stationary front will extend across southern MN into central WI and northern Lower MI, with little northward progress. Southerly winds across the warm sector will persist through the period and bring mid 50s F dewpoints northward toward the surface front. Much of the day looks to be capped, but increasing lift after 00Z along with persistent moistening from the southwest will result in elevated instability, possibly extending as far northern WI/Lower MI. Deep-layer shear will favor hail. A conditional risk of a few severe storms may also develop south of the boundary from eastern IA into northern IL as the low-level jet increases during the evening. In addition to hail, the warm/dry sub-cloud layer would favor potential damaging gusts with any cluster of storms. ..Jewell.. 03/28/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
