SPC 0830Z Day 3 Outlook

Day 3 Convective Outlook  
NWS Storm Prediction Center Norman OK
0152 AM CST Tue Dec 17 2024

Valid 191200Z - 201200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
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.
