AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
958 AM PST FRI MAR 6 2015

.SYNOPSIS...A HIGH PRESSURE RIDGE OVER THE WEST WILL BRING BRING
CLEAR SKIES AND ABOVE NORMAL TEMPERATURES TO THE DISTRICT THROUGH THE
WEEKEND. THE RIDGE WILL MAINTAIN THROUGH MONDAY AND TUESDAY WITH
NEAR NORMAL TEMPERATURES. BY LATE TUESDAY NIGHT OR WEDNESDAY THE
NEXT PACIFIC FRONT WILL APPROACH THE COAST BRINGING A CHANCE OF
RAIN TO THE AREA.

&&

.DISCUSSION...AS OF 9:30 AM PST FRIDAY...SKIES ARE CLEAR ACROSS
THE DISTRICT AND MORNING TEMPERATURES ARE ALREADY WARMING AHEAD OF
SCHEDULE. CURRENT TEMPERATURE READINGS ARE IN THE 50S AND
60S...SEVERAL DEGREES WARMER THAN YESTERDAY AT THIS TIME. SURFACE
PRESSURE GRADIENTS ARE OFFSHORE...6.3 MB FROM WMC TO SFO...AND 2.2
FROM ARCATA TO SAN FRANCISCO. EXPECT PLEASANT WEATHER TODAY AND
THROUGH THE WEEKEND WITH LIGHT WINDS AND ABOVE-NORMAL
TEMPERATURES. SUNNY SKIES WITH HIGH TEMPS FROM THE UPPER 60S AT THE
BEACHES...70S AROUND THE BAY AND EVEN SOME LOWER 80S FOR THE
INLAND VALLEYS OF MONTEREY/SAN BENITO COUNTY CAN BE EXPECTED. LOOKS
LIKE AN IDEAL WEEKEND FOR OUTDOOR ACTIVITIES ACROSS THE BAY AREA
INCLUDING THE BEACHES.

THE RIDGE IS FORECAST TO WEAKEN SLIGHTLY BY MONDAY AND TUESDAY
WITH PERHAPS SOME INCREASE IN ONSHORE FLOW NEAR THE COAST BUT
ONLY SLIGHTLY COOLER TEMPERATURES ARE FORECAST THROUGH AT LEAST
TUESDAY.

NEXT WEATHER ITEM OF INTEREST WILL BE AN INCOMING PACIFIC FRONT.
LATEST MODEL SOLUTIONS ARE STILL GIVING CONFLICTING OUTCOMES
REGARDING RAIN CHANCES NEXT WEEK. THE GEM (CANADIAN MODEL) HAS
RAIN SPREADING ACROSS THE CWA LATE TUESDAY THROUGH THURSDAY...HOWEVER
THE LATEST OPERATIONAL RUN OF THE GFS KEEPS THE AREA DRY. WILL
HAVE TO CHECK WITH OTHER OUTPUT...BUT RIGHT NOW WE HAVE A CHANCE
OF RAIN MENTIONED FOR THE END OF THE FORECAST PERIOD. NEEDLESS TO
SAY...CONFIDENCE REMAINS LOW.

&&

BREEZE PUSH LATE THIS AFTERNOON. RELATIVELY LIGHT WINDS TONIGHT.
