Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1116 AM CST Sun Nov 21 2021
Valid 221200Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected across the contiguous United
States on Monday.
...Synopsis and Discussion...
A large-scale upper trough centered over much of the central/eastern
CONUS on Monday will move eastward while gradually deepening. At the
surface, a cold front will likely stretch from eastern NY over the
Mid-Atlantic and off the central Gulf Coast at the start of the
period Monday morning. As this front continues eastward/southward
through the day, stable conditions will generally prevail in its
wake across the central/eastern states. One exception will be over
parts of south FL, where isolated afternoon thunderstorms appear
possible along/ahead of the front. Poor mid-level lapse rates, weak
convergence along the front, and modest low-level winds are expected
to greatly limit any severe threat across this region.
