Severe thunderstorms are not expected on Thursday. ....Synopsis... An upper trough extending along the Atlantic coast into the eastern Gulf of Mexico will shift east across FL and moving offshore early in the forecast period. Meanwhile, a shortwave trough over the northern/central Plains will deepen and pivot east, maintaining a mean upper trough over the eastern U.S. through the period. A surface cold front will be located over north-central FL Thursday morning, and quickly develop south through the day. Weak instability is forecast ahead of the front across portions of the southeast FL Peninsula, supporting isolated thunderstorms. Poor midlevel lapse rates and very weak low and midlevel flow will preclude severe thunderstorm potential. ...Leitman.. 12/17/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
