Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0216 AM CST Sun Dec 05 2021
Valid 071200Z - 081200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Severe thunderstorms are not forecast across the contiguous United
States on Tuesday.
...Synopsis and Discussion...
Large-scale upper troughing should once again develop across much of
the central/eastern CONUS on Tuesday as a lead wave ejects from New
England northeastward over the Canadian Maritimes. Surface high
pressure is expected to dominate much of the CONUS east of the
Rockies as it slowly shifts eastward to the Atlantic Coast through
the period. Due to a prior frontal passage, rich low-level moisture
is forecast to remain confined to parts of the immediate Gulf Coast.
Only very weak boundary-layer instability is forecast to develop
across parts of north FL Tuesday afternoon, and the potential for
robust thunderstorms appears low. However, some elevated convection
may occur mainly Tuesday evening/night from coastal TX to the
central Gulf Coast states as modest low-level warm/moist advection
develops on the southern periphery of the amplifying upper trough.
