Area forecast discussion, Jan 8, 9:35 PM PST, 4 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
935 PM PST SUN JAN 8 2012

.DISCUSSION...AS OF 7:57 PM PST SUNDAY...OFFSHORE WINDS CONTINUE
TO SUBSIDE THIS EVENING. THE OFFSHORE GRADIENT IS STILL AROUND 10 MB
BUT IS SLOWLY DECREASING. THE AIRMASS OVER THE REGION IS DRY WITH
DEWPOINTS IN THE 20S. A FEW HIGH CLOUDS CONTINUE TO MOVE OVER THE
STATE FLOW AROUND THE UPPER HIGH. EXPECT LIGHTER OFFSHORE WINDS IN
THE HILLS TONIGHT WITH THE DRY AIRMASS TO ALLOW FOR RADIATIONAL COOLING
IN THE VALLEYS.

NOT MUCH CHANGE WEATHERWISE MONDAY WITH CONTINUED LIGHT OFFSHORE
WINDS AND MOSTLY SUNNY SKIES. LIGHT ONSHORE WINDS ARE LIKELY BY
LATE MONDAY. AN UPPER LOW WILL HEAD TOWARDS CAPE MENDOCINO TUESDAY.
THE MODELS PREDICT THIS WILL STAY JUST OFFSHORE WITH PERHAPS SOME
SHOWERS OVER OUR OFFSHORE COASTAL WATERS. CONFIDENCE LEVELS ARE
NOT REALLY HIGH WITH THE LATEST SOLUTIONS SINCE THERE HAS BEEN DAY
TO DAY DIFFERENCES IN SOLUTIONS.

MODELS CONTINUE TO SHOW DRY WEATHER CONDITIONS FOR THE NEAR
FUTURE. TYPICALLY THERE IS A SHORT LIVED DRY SPELL THIS TIME OF
YEAR. SOME INDICATIONS ARE THERE THAT A STRONG BLOCKING HIGH WILL
DEVELOP OVER THE ALASKA ALEUTIANS WHICH CAN THEN REDIRECT THE MAIN
STORM TRACK SOUTHWARD WHICH WOULD VERY LIKELY BRING PRECIPITATION
TO THE AREA.

&&

.AVIATION...AS OF 9:35 PM PST SUNDAY...VFR THROUGH THE PERIOD WITH
ONLY POSSIBLE PROBLEM NEAR KSTS TONIGHT WHERE LIFR CIGS AND VIS
ARE EXPECTED. HIGH CONFIDENCE.

VICINITY OF KSFO...VFR THROUGH THE PERIOD WITH MAINLY LIGHT AND VARIABLE
WINDS. HIGH CONFIDENCE.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...VFR THROUGH THE PERIOD WITH LIGHT AND VARIABLE
WINDS. HIGH CONFIDENCE.
