Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1018 AM CST Tue Jan 12 2021

Valid 121630Z - 131200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for organized thunderstorms appears negligible through
tonight.

...TX...
Two areas of deep convection have developed this morning - one over
south TX and the other off the Lower TX Gulf Coast.  Both of these
areas of showers and very isolated thunderstorms are highly
elevated, with forecast soundings showing the unstable layer around
700mb and MUCAPE values near zero.  While isolated lightning flashes
may continue for another hour or so, it is likely that the coverage
of lightning after 1630z will be below 10%.

Elsewhere across the nation, relatively dry and stable conditions
will preclude organized thunderstorm activity.
