widely scattered thunderstorms are expected over a portion of the 
southwestern U.S. Wednesday. 

..southwestern states... 

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.
