Limited risk for a few strong wind gusts or a brief tornado may evolve late Wednesday night/Thursday morning, across a portion of the mid Mississippi/lower Ohio Valley area. ....Synopsis... An upper trough initially over the Rockies is forecast to move eastward across the Plains through the day, and then to the Mississippi Valley vicinity late, while deepening gradually with time. As this trough advances, a surface cyclone is forecast to pivot eastward from the central High Plains vicinity, to the lower Ohio Valley by the end of the period. ....Parts of the Mid-Mississippi and lower Ohio Valleys... As the aforementioned surface low advances, a cold front will shift southeastward across the southern Plains/Arklatex and eventually the Mississippi Delta region through the second half of the period. Ahead of the front, northward advection of a partially modified airmass will occur, beneath a pronounced low-level thermal inversion. While the strong capping will largely hinder convective development, showers and a few thunderstorms may develop during the last several hours of the period across the Mid Mississippi/lower Ohio Valley vicinity. While CAPE will be quite limited (no more than a few hundred J/kg at most is anticipated), a strong kinematic environment -- including veering/increasing flow with height -- would support organized/rotating updrafts. However, given the persistent capping and very weak instability anticipated in areas where the cap can weaken, suggests only a very limited potential for a strong gust or two, or a brief/weak tornado. ...Goss.. 01/10/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
