   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...

   ...SUMMARY...
   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.
