Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0547 AM CST Thu Dec 10 2020

Valid 101300Z - 111200Z


Sporadic general thunderstorms are expected from the Southwest to
the southern Great Plains through early Friday.

...Southwest to southern Great Plains...
A shortwave trough near the AZ/Sonora border will dampen as it
ejects into the southern/central High Plains by daybreak Friday.
Thunderstorm potential should be focused within two regimes. The
first will be across the Southwest where pockets of scant buoyancy
near the mid-level thermal trough should promote isolated thunder
through about sunset. The second regime will be centered within the
700-mb warm theta-e advection zone where meager elevated buoyancy
should become increasingly prevalent, beginning in west TX this
evening and spreading east/northeast into OK and central portions of
TX tonight.
