Day 1 Convective Outlook

1048 PM CST Tue Nov 25 2025
Valid 261200Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe storms are not forecast today.
...Synopsis...
A deep upper low will move across the upper Great Lakes and into
southwest Quebec, with a large area of cyclonic flow aloft across
the central and eastern CONUS. Meanwhile, an upper ridge will exist
over the West, but will weaken as an upper low approaches the
Pacific Northwest toward Thursday morning.
At the surface, a deep low will also move from the Great Lakes
region into western Quebec, with a large area of high pressure over
the Plains and extending into the southeastern states and into the
Gulf.
While a cold front will be located over the central Carolinas and
into the FL Panhandle early this morning, this boundary will push
rapidly offshore by midday. Early day rain and a few thunderstorms
will be possible along the front, but should generally weaken due to
drying aloft.
Elsewhere, lingering thunderstorms will be possible over far
southern Texas as the cold front undercuts moisture over Deep South
TX. This activity is also expected to weaken and/or be mostly
offshore during the rest of the day, as drying continues over land.

Day 2 Convective Outlook

Valid 271200Z - 281200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across southeast Florida on
Thursday. Severe storms are not expected.
...Synopsis...
A broad mid-level trough will deepen across the eastern CONUS,
ushering in surface high pressure and associated cool and stable air
across most of the CONUS, limiting thunderstorms over most locales
tomorrow (Thursday). The one exception will be the southern FL
Peninsula tomorrow afternoon and evening. Here, a surface cold front
will sweep across the region, lifting a moist and buoyant low-level
airmass before moving offshore. Isolated thunderstorms are possible
during the afternoon hours, before the cold front clears moisture
from the region.
