...NO SVR TSTM AREAS FORECAST...

...SRN CA COAST EWD INTO THE LOWER CO VALLEY...
REGIONAL RADAR IMAGERY SHOWS A CLUSTER OF TSTMS OVER LOS
ANGELES/ORANGE AND WRN PORTIONS OF SAN BERNARDINO AND RIVERSIDE
COUNTIES MOVING NEWD AHEAD OF SHORTWAVE TROUGH MOVING ONTO THE SRN
CA COAST. CLOUD COVER ACROSS THIS AREA HAS LIMITED DAYTIME HEATING
AND RESULTANT DESTABILIZATION SO FAR TODAY. HOWEVER...FAVORABLE
SHEAR PROFILES OBSERVED ON NKX AND SOX VWPS HAS SUPPORTED SEVERAL
MINI SUPERCELLS WHICH HAVE MOVED ONSHORE OVER COURSE OF THE MORNING.
EXPECT THAT SUPERCELL AND ISOLATED TORNADO THREAT WILL TEND TO
DIMINISH THIS AFTERNOON AS STRONGEST FORCING ASSOCIATED WITH
SHORTWAVE TROUGH SHIFTS EWD AWAY FROM THE PACIFIC AND ADJACENT COAST
WHERE STRONGER INSTABILITY CURRENTLY RESIDES. MOST VIGOROUS STORMS
WILL REMAIN CAPABLE OF MARGINALLY SEVERE HAIL AND ISOLATED STRONG
WIND GUSTS INTO THIS EVENING.

FARTHER E...STRONGER DIABATIC HEATING HAS OCCURRED OVER THE LOWER CO
 VALLEY OF NWRN AZ AND SRN NV WHERE SBCAPES HAVE INCREASED TO
500-1000 J/KG. EXPECT TSTMS TO INCREASE IN COVERAGE AND INTENSITY
THIS AFTERNOON AS LARGE-SCALE FORCING ASSOCIATED WITH AFOREMENTIONED
SHORTWAVE TROUGH BEGINS TO OVERSPREAD THE REGION FROM THE W. HERE
TOO...MOST VIGOROUS STORMS WILL BE CAPABLE OF ISOLATED HAIL AND
STRONG WIND GUSTS. FOR ADDITIONAL SHORT TERM GUIDANCE...PLEASE SEE
