Isolated to scattered strong to severe storms are possible Saturday from the central/northern Plains to Lower Michigan. ....Discussion... Thunderstorms may be ongoing Saturday morning along a frontal zone from the northern Plains to the western Great Lakes. The location and strength of this morning convection will have significant impacts on more focused zones of severe weather threat on Saturday. A MCS may be ongoing across Wisconsin/northern Illinois/western Michigan on Saturday morning. This MCS or a remnant MCV in its wake, may provide a focus for severe storms across Lower Michigan Saturday afternoon. In addition, a MCS may be ongoing across eastern South Dakota and southwest Minnesota on the nose of the low-level jet. If the environment downstream of this MCS can destabilize during the morning, a severe weather threat may materialize as this MCS moves east along the front. If neither of these solutions occur, the severe weather threat may be somewhat more isolated. However, very strong to extreme instability is expected along the frontal zone with sufficient shear for some storm organization. Strong heating in the Plains may result in a few isolated high-based storms from central Nebraska to western South Dakota and potentially into far southwest Montana with a primary severe wind threat during the afternoon/early evening. Convection is expected along most of the frontal zone from eastern South Dakota to Michigan Saturday night as the low-level jet strengthens and height falls overspread the region. Isolated large hail is possible from these storms. ...Bentley.. 08/14/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
