A low chance of a few thunderstorms may develop on Friday near the Upper Ohio Valley and vicinity, and also near the southeast Florida coast. ...Synopsis... An upper ridge will remain over the Southwest on Friday, with strong northwest flow aloft along the Canadian border. A low-amplitude upper wave will move from northern MN across the upper Great Lakes late in the day and overnight, with a weak surface low moving from the Great Lakes into the Northeast. A cold front will extend from southwest Ontario into MO by 18Z, with southwesterly surface winds helping to bring a plume of low to mid 50s F dewpoints as far north as OH and western PA. Marginal low-level moistening and daytime heating will lead to weak instability, which may support isolated thunderstorms developing within the warm advection zone into the Upper OH Valley and vicinity. Severe storms are not forecast due to the weak instability, however, veering winds with height and good deep-layer shear will support cellular activity, perhaps with very small/non-severe hail. Elsewhere, the tail-end of the western Atlantic trough will maintain cool temperatures aloft over FL. This will support afternoon destabilization, with isolated activity near the eastern shores where localized surface convergence may develop. ..Jewell.. 03/19/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
