AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
854 PM PDT SUN AUG 19 2012

.DISCUSSION...AS OF 8:52 PM PDT SUNDAY...STRATUS CONTINUES TO FILL
IN ALONG THE COAST TONIGHT. THE MARINE LAYER IS ROUGHLY 1000-1100
FEET DEEP AT THE MOMENT. ONSHORE PRESSURE GRADIENTS ARE NEARLY 4
MB FROM SFO-SAC. WEST WINDS WILL CAUSE MORE STRATUS TO MOVE INLAND
OVERNIGHT. HIGHS TODAY RANGED FROM THE LOWER 60S AT THE COAST TO
THE LOWER 100S INLAND VALLEYS. PARKFIELD REACHED 102F FOR INSTANCE.

A DRY MODERATE MID LEVEL TROUGH WILL APPROACH THE AREA VERY LATE
MONDAY NIGHT INTO TUESDAY. IT WILL BE AN OPEN WAVE TROUGH TUESDAY
FORMING INTO A CLOSED LOW AS IT REACHES THE SOUTHERN SAN JOAQUIN
VALLEY WEDNESDAY. DURING THIS TIME EXPECT THE MARINE LAYER TO
GRADUALLY DEEPEN TO MODERATE TO DEEP LEVELS PROBABLY UP TO BETWEEN
2-3 THOUSAND FEET OR POSSIBLY EVEN HIGHER. IF ENOUGH MIXING AND
COOLING ARE PRESENT THAN THIS WILL MIX OUT THE MARINE LAYER CLOUDS
REVEALING PARTLY CLOUDY SKIES. THE OVERALL IMPACT OF THE LOW WILL
BE TO CAUSE GRADUAL COOLING ACROSS INLAND VALLEYS AT LEAST AS MUCH
AS 5 TO MAYBE 10 DEGREES.

THE TROUGH EXITS THE REGION BY LATE WEEK BEING REPLACED BY A WEAK
RIDGE FRIDAY AND SATURDAY. WEAK TROUGHING WILL RETURN BY SUNDAY.
DURING THIS TIME THE MARINE LAYER CLOUDS WILL LIKELY REDEVELOP TO
SOME EXTENT. HIGH PRESSURE WILL QUICKLY RETURN LATE IN THE WEEKEND
AND POSSIBLY EARLY NEXT WEEK. THIS MAY SET THE STAGE FOR A WARM TO
HOT WEATHER EVENT EARLY NEXT WEEK.
