AIR MASS OVER CWA IS SLOWLY WARMING AS RIDGE BUILDS OVER THE WEST 
COAST. WITH PLENTY OF DRY AIR MOVING IN ALOFT EXPECT TONIGHT WILL BE 
MUCH COLDER OVER MOST OF THE CWA. AT THE COAST WE SHOULD SEE NEAR 
FREEZING TEMPS...SO WILL ISSUE A FROST ADVISORY. INLAND IT SHOULD 
END UP IN THE 20S MOST PLACES EXCEPT WHERE LOW CLOUDS SET UP AND 
SLOW THE COOLING. AS OFFSHORE FLOW CONTINUES EXPECT LESS LOW LEVEL 
MOISTURE EACH NIGHT. BUT THE AIR MASS WILL BE WARM ENOUGH TO KEEP 
OVERNIGHT LOWS FRIDAY NIGHT JUST A LITTLE HIGHER OVERALL AT THE 
COAST...AND PRETTY SIMILAR INLAND.  

TOUGHER CALL IN THE EXTENDED FORECAST. MODELS ALL KEEP A MEAN RIDGE 
POSITION OVER THE WEST COAST...BUT UNDERCUT IT IN ONE WAY OR ANOTHER 
ON MONDAY. FOR NOW WILL CONTINUE TO LEAN TOWARD THE POSSIBILITY OF A 
TROUGH SPLITTING AS IT APPROACHES THE COAST...THEN FORMING A CUT OFF 
LOW THAT MOVES SOUTH TOWARD THE CENTRAL COAST. 12Z AVN...NOGAPS... 
AND MRF ALL SUPPORT THIS PATTERN. IN A NOD TO THAT PATTERN WILL PUT 
A CHANCE OF SHOWERS IN MENDOCINO COUNTY FOR MONDAY.

POPS CEC 0000 EKA 0000 UKI 0000.
