A low chance of a few thunderstorms may develop near the Upper Ohio Valley and vicinity on Friday. ...Synopsis and Discussion... An upper ridge will hold over the Southwest on Friday, with strong northwest flow aloft along the Canadian border. A low-amplitude upper wave will intensify into northern MN and toward the upper Great Lakes late in the day and overnight, with a weak surface low also traversing the Great Lakes. A cold front will extend from southwest Ontario into IL and MO by 00Z, and southerly winds ahead of it will bring a plume of low to mid 50s F dewpoints northward across TN/KY/IN/OH during the afternoon. Despite the low-level moistening, instability will likely be minimal. However, weak elevated instability may develop within the warm advection zone roughly from OH into PA, with a low chance of isolated thunder. ..Jewell.. 03/18/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
