...NO SVR TSTM AREAS FORECAST...

...CA AND ORE COAST...
A CLOSED-OFF UPPER LOW WILL OPEN AND MOVE INLAND ACROSS CA AND ORE
TODAY. THE STRONG ASCENT ASSOCIATED WITH THE WAVE AND COLD TEMPS
ALOFT /500 MB TEMPS OF -30 C/ WILL CREATE FAVORABLE CONDITIONS FOR
SCATTERED THUNDERSTORMS THIS AFTERNOON. HOWEVER...THE STEEP LAPSE
RATES AND STRONG FORCING WILL SHIFT EWD DURING THE LATE AFTERNOON
HOURS AS THE TROUGH MOVES INLAND INTO THE DESERT SOUTHWEST. THIS
WILL ALLOW MOST OF THE THUNDERSTORM ACTIVITY TO DECREASE ACROSS THE
REGION BY EARLY THIS EVENING

...LOWER TO MID MS VALLEY...
ONSHORE FLOW WILL CONTINUE IN TX AND LA ALLOWING FOR SFC DEWPOINTS
TO SLOWLY RISE TODAY. AS AN UPPER-LEVEL TROUGH MOVES EWD INTO THE
ROCKIES...LOW TO MID-LEVEL FLOW WILL STRENGTHEN QUICKLY ACROSS TX
AND LA TONIGHT. AS FLOW INCREASES...ANY DISTURBANCE IN THE MID-LEVEL
FLOW COULD SET OFF A FEW THUNDERSTORMS LATE IN THE PERIOD ACROSS THE
LOWER MS VALLEY AND OZARKS. DUE TO WEAK LAPSE RATES...THE STORMS
SHOULD REMAIN BELOW SEVERE LIMITS.
