Valid 201200z - 211200z
..no severe thunderstorm areas forecast...
widely scattered thunderstorms are expected over a portion of the
southwestern U.S. Wednesday.
Synoptic upper trough will advance inland through California Wednesday,
continuing into the Great Basin Wednesday night. Cold temperatures
aloft with -24 to -26 c at 500 mb and pockets of diabatic heating
will steepen lapse rates supporting 200-400 j/kg MLCAPE. Forcing for
ascent attending embedded vorticity maxima along with modest
destabilization should support development of widely scattered
thunderstorms within a more general area of showers during the day
and continuing into the evening.
