Day 3 Convective Outlook  

NWS Storm Prediction Center Norman OK

0211 AM CST Fri Dec 12 2025



Valid 141200Z - 151200Z



...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

A few storms are possible across South Florida and the Florida Keys

on Sunday.



...Synopsis...

A mid-level trough will advance from the Great Lakes to the western

Atlantic on Sunday. To the west, a ridge will remain centered across

the western CONUS. On the eastern periphery of this ridge, a

secondary mid-level shortwave trough will move into the Upper

Midwest. A very strong (1040mb+) area of high pressure will build

into the eastern 2/3rds of the CONUS Sunday and push a strong cold

front into the Gulf by Sunday evening. 



...South Florida...

A weak mid-level shortwave trough will approach the west coast of

Florida on Sunday morning. As this trough advances east, isolated to

widely scattered thunderstorms are possible across far south

Florida. Weak lapse rates should limit storm intensity overall.

Storms should wane by the evening as the boundary layer cools and

northerly flow strengthens and brings cooler, drier air by Sunday

night.
