Day 2 Convective Outlook

1159 PM CST Thu Dec 11 2025



Valid 131200Z - 141200Z



...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Isolated weak thunderstorm activity is possible across South Florida

and the Keys Saturday afternoon into Saturday night.



...Synopsis...

The large-scale pattern on Saturday will feature a ridge across the

western CONUS with troughing across the east. This mid-level trough

will amplify on Saturday as a strong mid-level jet streak moves from

the northern Plains to the Midwest. At the surface, a cold front

will sharpen from the Ohio Valley to the Plains and move south

rapidly Saturday evening. 



...South Florida...

Tropical moisture will start to advect northward across the southern

Florida Peninsula on Friday. If this advects far enough north during

the day, a few thunderstorms may be possible on the eastern sea

breeze. During the overnight period, storm chances will increase

across the western Florida Peninsula as a mid-level shortwave trough

traverses the Gulf. Limited instability should preclude any severe

weather threat from this activity. 



Shallow convection may develop along the southward moving cold front

from southeast Texas to central Alabama late Saturday night, but

warm temperatures aloft should limit lightning potential.
