Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1044 PM CST Thu Nov 19 2020

Valid 201200Z - 211200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for thunderstorms is expected to remain very low through
tonight.

...Synopsis...
Thunderstorm potential is expected to remain quite limited through
tonight, due to a general lack of buoyancy across the CONUS. 

...South FL...
Convective showers will be possible across south FL through much of
the period, but warm midlevel temperatures and a lack of large-scale
ascent should limit the potential for deep convection capable of
producing lightning. 

...Four Corners...
Gradually increasing moisture and cooling midlevel temperatures may
support very weak buoyancy later tonight in the Four Corners region,
but potential for lightning with any shower activity appears too
limited for a thunderstorm area at this time. 

...Ozark Plateau...
Southerly return flow will result in gradual moistening into the
Ozark Plateau through tonight, along the western periphery of a
surface ridge over the Southeast. While some convective showers may
develop late tonight into Saturday morning, potential for deep
convection appears too limited to delineate a thunderstorm area.
