Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0626 PM CST Wed Dec 11 2019

Valid 120100Z - 121200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected tonight.

...South Florida...

Convergence along a slow-moving cold front will continue to promote
a few thunderstorms over a portion of south FL through about 03Z.
However, a stabilizing boundary layer will result in a gradual
diminishing trend.

...Western Washington State...

Destabilization and steepening lapse rates resulting from cooling
mid-level temperatures accompanying a low-amplitude shortwave trough
will spread through western WA later tonight, resulting in 100-300
J/kg MUCAPE. Scattered convection developing in this regime might
become capable of producing a few lightning flashes late in the
period.

...Northern New York...

Isolated lightning flashes will remain possible through 02Z in
association with a lake effect snow band downwind of Lake Ontario.
However, tendency will be for equilibrium levels to gradually fall
as heights and 700-800 mb temperatures rise in wake of a progressive
shortwave trough.
