...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected today.
...Synopsis and Discussion...
Broadly cyclonic flow will be maintained over much of the central
and eastern CONUS today. Appreciable low-level moisture to support
thunderstorms will remain generally confined along/south of a cold
front extending from the Gulf northeastward across the central FL
Peninsula and into the western Atlantic. Large-scale ascent and
low-level convergence along this boundary are both forecast to
remain weak, with poor lapse rates aloft also contributing to
limited instability over land. While an occasional shower may reach
sufficient height to support charge separation and lightning across
parts of the central FL Peninsula, the overall coverage of
thunderstorms over land should remain quite isolated.

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook

1013 AM CST Sat Dec 06 2025
Valid 061630Z - 071200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected today.
...Synopsis...
A progressive flow pattern will remain over the Lower 48 states
today. In the low levels, a front will reside over the Gulf and
extend east-northeastward across the northern half of the FL
Peninsula and east of the Carolina coast. The 12 UTC Tampa, FL raob
showed poor lapse rates. Limited buoyancy coupled with
weak/negligible low-level convergence/large-scale ascent will act to
limit convective coverage and intensity across the central FL
Peninsula today.
