OTHER THAN THE CIRRUS LEVEL MOISTURE...ATMOSPHERE STILL REALLY DRY
OVER THE AREA TONIGHT. ALTHOUGH THE VBG SOUNDING SHOWED AN INCREASE OF
MOISTURE IN THE LOWER LEVELS AND MARINE INVERSION DEVELOPING AROUND
500 FEET. SFC PRES GRADS ARE GENERALLY +/-1...BUT AS UPR LVL TROUGH IN
THE ERN PAC EDGES EAST THURSDAY...GRADS WILL BEGIN A DEFINITE TREND
ONSHORE. THIS WILL COOL THE COASTAL AREAS AND ESP...THE CENT COAST
THURS. INLAND AREAS WILL BE NEARLY AS WARM AS TODAY. GRADS TREND EVEN
STRONGER ONSHORE FOR FRIDAY AS SFC LOW DEVELOPS OVR GREAT BASIN AND
UPR TROUGH REACHES US. THIS WILL MEAN A SIGNIFICANT COOL DOWN FOR FRI. 

DEEPEST MOISTURE AND BEST DYNAMICS REMAIN NORTH OF THE AREA...GIVING
THE SBA/SLO COUNTIES THE BEST CHC OF SHOWERS FRIDAY AFTN INTO SAT.
BEST CHC OF PRECIP DOWN SOUTH WILL BE FROM A DEEPENING MARINE LAYER
THAT SQUEEZES OUT SOME DRIZZLE. FLOW TURNS NORTH BEHIND THE TROUGH AND
DRIES THE AREA OUT...BUT KEEPS TEMPS COOL FOR SUN. THEN AN UPR RIDGE
MOVES IN AND AMPLIFIES EARLY NEXT WEEK...PROVIDING US WITH DRY AND
WARMER WEATHER.

MOSTLY CLEAR FOR TONIGHT MAY SOUND A BIT OPTIMISTIC...BUT I DONT SEE
THE NEED TO UPDATE ZONES IN ORDER TO DIFFERENTIATE BETWEEN MOSTLY
CLEAR/PARTLY CLOUDY OR VARIABLE HIGH CLOUDS. ZONES ARE IN GOOD SHAPE.
