An upper-level ridge will move into the Rockies on Wednesday, as northwesterly mid-level flow remains from the Great Plains to the eastern U.S. On Thursday, the ridge will become less amplified as it moves into the Great Plains. At the surface, low-level moisture is forecast to return northward into the lower to mid Mississippi Valley. Within this moist airmass, a pocket of moderate instability is expected by late Thursday afternoon. Thunderstorm development will be possible near a front along the northern edge of the stronger instability from northeast Missouri east-northeastward into north-central Ohio. Storms are expected to move east-southeastward across the Ohio Valley on Thursday afternoon and evening. A severe threat will be possible, but the magnitude of any potential threat is still uncertain. ...Friday/Day 6 and Sunday/Day 8... From Friday into Saturday, a cold front is forecast to move southward from the mid Mississippi Valley to the central Gulf Coast. Isolated thunderstorms will be possible along parts of the front both Friday and Saturday afternoon. Weak instability should keep any severe threat marginal. On Sunday, the models are forecasting a dry airmass over most of the continental U.S., suggesting the potential for storms is low. ..Broyles.. 03/22/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
