...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE LOWER TO MID MISSISSIPPI VALLEY...
...SUMMARY...
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, co*bined 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.
