VALID 162000Z - 171200Z

...NO SVR TSTM AREAS FORECAST...

...CA COAST...

STRONG MID-LEVEL TROUGH CONTINUES TO DIG SEWD TOWARD THE CNTR/SRN CA
COAST WITH VISIBLE SATELLITE AND RUC OBJECTIVE FIELDS INDICATING A
BROAD REGION OF OCEANIC CELLULAR CONVECTION WITHIN AN ENVIRONMENT OF
STEEP LOW TO MID-LEVEL LAPSE RATES.  THIS TROUGH IS FORECAST TO MOVE
ONTO THE SRN CA COAST TONIGHT WITH STEEP LAPSE RATES MOVING INLAND. 
IT APPEARS THAT THE GREATEST THREAT OF TSTMS WILL EXIST ALONG THE
IMMEDIATE COAST...THOUGH THE POTENTIAL FOR ISOLATED THUNDER WILL
EXIST AS FAR E AS THE LOWER CO VALLEY.

...S FL AND THE KEYS...

A MOIST LOW-LEVEL AIR MASS EXISTS ACROSS THE REGION THIS
AFTERNOON...THOUGH CONSIDERABLE CLOUDINESS HAS LIMITED
DESTABILIZATION.  TSTMS CONTINUE TO INCREASE UPSTREAM FROM WRN CUBA
NWD IN ASSOCIATION WITH LOW LATITUDE IMPULSE TRANSLATING THROUGH THE
CNTRL/ERN GULF BASIN.  EXPECT THAT THE THREAT OF ISOLATED/SCATTERED
TSTMS WILL INCREASE OVERNIGHT AS THIS SYSTEM APPROACHES THE
PENINSULA.  OTHER STORMS WILL LIKELY PERSIST THROUGH THE AFTERNOON
ALONG WEAK BOUNDARY NEAR AND E OF VRB.
