...WEST COAST...

CURRENT WATER VAPOR IMAGERY SHOWS FULL-LATITUDE TROUGH ALONG THE
COAST WITH TWO DISTINCT VORTICITY MAXIMA LOCATED NEAR SFO AND JUST
NW OF VANCOUVER ISLAND.  AN AXIS OF RELATIVELY COLD /-28 TO -34 C AT
500 MB/ TEMPERATURES IS ASSOCIATED WITH THIS TROUGH WHICH IS
CONTRIBUTING TO STEEPENING MID-LEVEL LAPSE RATES FROM PUGET SOUND
INTO THE CNTRL VALLEY OF CA.  CONSIDERABLE CLOUDINESS HAS LIMITED
DAYTIME HEATING ACROSS MUCH OF THIS REGION...EXCEPT S AND SE OF SFO
WHERE TEMPERATURES HAVE WARMED THROUGH THE 50S.

POTENTIAL FOR ISOLATED TO WIDELY SCATTERED TSTM DEVELOPMENT SHOULD
INCREASE THIS AFTERNOON INTO EVENING FROM THE CA CNTRL VALLEY NWD AS
INCREASED LARGE-SCALE FORCING FOR ASCENT ASSOCIATED WITH SRN
VORTICITY MAXIMUM OVERSPREADS DESTABILIZING ENVIRONMENT.  FARTHER TO
THE N FROM NRN CA INTO WRN WA...CONFIDENCE IN TSTM DEVELOPMENT IS
NOT AS HIGH...THOUGH THE PERSISTENT FORCING FOR ASCENT AND
STEEPENING MID-LEVEL LAPSE RATES MAY SUPPORT A FEW ISOLATED
LIGHTNING STRIKES.
