AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1030 PM PDT MON JUL 11 2011

.DISCUSSION...AS OF 8:53 PM PDT MONDAY...COASTAL LOW CLOUDS ARE
CURRENTLY MAKING THEIR TREK INLAND ONCE AGAIN AT THIS HOUR.
EXTENSIVE LOW LEVEL CLOUD COVERAGE ACROSS THE CWA MADE FOR COOL
TEMPERATURES ACROSS THE BOARD. COASTAL LOCATIONS SAW TEMPERATURES
DROP A FEW DEGREES OVER YESTERDAYS HIGH WITH INLAND LOCATIONS SEEING
A SIGNIFICANTLY LARGER DECLINE IN TEMPERATURES WITH LOCATIONS SUCH
AS LIVERMORE COOLING SOME 12 DEGREES.

LITTLE CHANGE EXPECTED IN THE OVERALL FORECAST PATTERN THROUGH
MIDWEEK. NIGHT AND MORNING LOW CLOUDS AND BELOW NORMAL TEMPERATURES
EXPECTED TO CONTINUE. THE DEEPENING MARINE LAYER WILL LIKELY RESULT
IN AREAS OF DRIZZLE OVERNIGHT AND INTO THE MORNING HOURS. ANOTHER
ITEM OF NOTE IS THE WINDS IN THE HILLS. THE ALTAMONT RAWS IS
REPORTING SUSTAINED WINDS UP TO 38 MPH WITH GUSTS TO 47 MPH. THIS
WILL NEED TO BE MONITORED. HOWEVER IT APPEARS TO BE LOCALIZED AND
NOT WIDESPREAD ENOUGH TO WARRANT AN ADVISORY.

FROM PREVIOUS DISCUSSION...SHORT AND LONG TERM (TONIGHT-MONDAY)
NO MAJOR CHANGES FROM THE PREVIOUS FORECAST.  THE WEATHER PATTERN
THROUGH MID WEEK WILL BE DOMINATED BY THE DEEPENING TROUGH
CURRENTLY ALONG THE WEST COAST. THEREFORE...ONSHORE FLOW WILL REMAIN
KEEPING NIGHT AND MORNING STRATUS IN PLACE.  LOWERING H5 TONIGHT
WILL ALLOW FOR A SLIGHTLY DEEPER MARINE LAYER THAN LAST NIGHT.  IN
FACT...H5 ARE FORECAST TO REMAIN LOW INTO THURSDAY AS AN UPPER
LEVEL LOW CURRENTLY OFF THE BC COAST DROPS SOUTH.  JUST LIKE THIS
MORNING...THE DEEPENING MARINE LAYER MAY LEAD TO OCCASIONAL DRIZZLE
ALONG THE COASTLINE. AS NOTED ON SEVERAL DISCUSSIONS NOW...THE ONLY
REAL QUESTION DOES THE MARINE LAYER DEEPEN ENOUGH TO MIX OUT
WED/THUR? PRETTY HARD TO BET AGAINST STRATUS THIS TIME OF YEAR WITH
ONSHORE FLOW SO WILL KEEP STRATUS IN FOR NOW. SOMETHING TO WATCH
THOUGH.

THE PERSISTENT CLOUD COVER AND UPPER LEVEL TROUGH WILL ALSO LEAD
TO BELOW NORMAL TEMPERATURES INTO NEXT WEEKEND...MOST NOTABLY ACROSS
THE INTERIOR. THERE IS A GLIMMER OF HOPE TOWARD THE END OF THE
FORECAST PERIOD WHERE TEMPERATURES WILL LIKELY REBOUND TO
SEASONABLE LEVELS.

&&

.AVIATION...AS OF 10:30 PM PDT MONDAY...SATELLITE SHOWS COASTAL
STRATUS MOVING LOCALLY INLAND SIMILAR TO LAST NIGHT.

VICINITY OF KSFO...WEST WINDS STILL GUSTY BUT UNDER 20 KNOTS AT
THE MOMENT WHERE IT WILL LIKELY REMAIN OVERNIGHT. MVFR CIGS INCLUDING
TEMPO IFR BETWEEN 11Z-15Z TUESDAY.

KSFO BRIDGE APPROACH...INCREASING LOW CLOUDS OVERNIGHT.

MONTEREY BAY AREA TERMINALS...SIMILAR TO LAST FEW DAYS LOW CLOUDS
WILL CONTINUE TONIGHT. IFR IS LIKELY.

&&

.MTR WATCHES/WARNINGS...
     .TNGT...SCA...PIDGEON POINT TO POINT PIEDRAS BLANCAS 10-60 NM.
          ...SCA...PIDGEON POINT TO POINT PIEDRAS BLANCAS 0-10 NM.
