Thunderstorms, associated with isolated severe wind gusts and hail, will be possible on Thursday across parts of the lower to mid Mississippi Valley. ....Lower to Mid Mississippi Valley... An upper-level trough is forecast to move through the Upper Midwest and Ozarks on Thursday, as a cold front advances southeastward into the mid Mississippi Valley and Ark-La-Tex. Ahead of the front, surface dewpoints will be in the 60s F, enabling the development of weak instability as surface temperatures warm up during the day. Increasing instability and low-level convergence along the front will result in scattered thunderstorm development Thursday afternoon. Low to mid-level flow will weaken across the lower to mid Mississippi Valley on Thursday as the upper-level trough moves further away. This, combined with weak instability and poor low-level lapse rates will minimize any severe threat that develops. In areas that heat up the most, a marginal severe threat will be possible. The stronger cells could be associated with isolated severe wind gusts and hail. ...Broyles.. 10/29/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
