AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1030 PM PDT SAT APR 30 2011

.DISCUSSION...AS OF 8:45 PM PDT SATURDAY...PLENTY OF WARM LATE APRIL
SUNSHINE AND A MUCH WEAKER SEABREEZE ALLOWED TEMPERATURES TO WARM A
FEW DEGREES ABOVE NORMAL TODAY. AFTERNOON HIGHS WERE GENERALLY IN THE
UPPER 60S AND 70S. THE WARMING TREND WILL CONTINUE INTO SUNDAY AS AN
UPPER RIDGE STRENGTHENS ALONG THE WEST COAST AND THE SURFACE PRESSURE
PATTERN CONTINUES TO SUPPORT ONLY A LIGHT AFTERNOON SEABREEZE. LOOK
FOR SOME OF THE WARMER INTERIOR VALLEYS TO CLIMB ABOVE 80 DEGREES ON
SUNDAY AFTERNOON.

THE WARMING TREND WILL STALL TEMPORARILY ON MONDAY WHEN A SHORTWAVE
TROUGH MOVING INTO THE PACIFIC NORTHWEST FLATTENS THE RIDGE ALONG
THE WEST COAST. IN FACT...TEMPERATURES WILL PROBABLY COOL SOME FROM
SUNDAY INTO MONDAY GIVEN THE INCREASE IN ONSHORE FLOW EXPECTED ON
MONDAY. MONDAY'S COOLING WILL BE MOST NOTICEABLE NEAR THE COAST.
AREAS WELL INLAND WILL PROBABLY SEE LITTLE CHANGE ON MONDAY.

THE CURRENT FORECAST MAINTAINS MOSTLY CLEAR SKIES THROUGHOUT THE
WEEK. WILL NEED TO CONSIDER ADDING SOME LOW CLOUDS ALONG THE COAST ON
MONDAY NIGHT AND TUESDAY MORNING GIVEN THE EXPECTED INCREASE IN
ONSHORE FLOW EARLY IN THE WEEK.

THE WARMING TREND WILL RESUME BY TUESDAY AFTERNOON AS AN UPPER RIDGE
BEGINS TO BUILD JUST OFFSHORE. BUT THE BIGGEST UPTICK IN TEMPERATURES
WILL PROBABLY BE ON WEDNESDAY WHEN THE RIDGE BUILDS ALONG THE
WEST COAST...850 MB TEMPERATURES INCREASE TO 16 DEGREES C...AND
LIGHT OFFSHORE FLOW DEVELOPS. COASTAL AREAS SHOULD SEE TEMPERATURES
WARM WELL INTO THE 70S ON WEDNESDAY...WITH MAYBE EVEN A FEW LOWER
80S. INLAND AREAS WILL WARM INTO THE 80S AND LOWER 90S. NOT MUCH
CHANGE IS THEN EXPECTED ON THURSDAY...EXCEPT PERHAPS A FEW MORE
DEGREES OF WARMING INLAND.

TEMPERATURES WILL PROBABLY COOL BACK TO NEAR NORMAL LATE IN THE WEEK
AND INTO NEXT WEEKEND AS A PASSING SHORTWAVE TO OUR NORTH TURNS THE
FLOW ALOFT MORE ZONAL.
