AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
1045 AM PDT WED JUN 24 2009

.DISCUSSION...AS OF 10:05 AM PDT WEDNESDAY...AN AREA OF LOW PRESSURE
EVIDENT ON THE SATELLITE WATER VAPOUR IMAGE IS PROVIDING SOUTHERLY
WINDS OVER THE COASTAL WATERS THIS MORNING. STRATUS IS PRESENT ALONG
THE CENTRAL COAST AND IS PUSHING INTO THE SALINAS VALLEY AND INTO
LOW LYING AREAS ALONG MONTEREY BAY. SOME CUMULUS ASSOCIATED WITH
THE LOW IS ALSO APPARENT OVER THE COASTAL WATERS.

ACCORDING TO THE 1200 UTC KOAK SOUNDING THE MARINE LAYER IS APPROX
1500 FEET DEEP WITH A SIGNIFICANTLY DRY ATMOSPHERE PRESENT ALOFT.
AMSU TPW VALUES ARE AROUND 0.60 INCHES JUST OFF THE COAST
FURTHER ILLUSTRATING A DRY ATMOSPHERE ALOFT. THIS DRY AIR ALOFT
WILL LIMIT ANY CONVECTIVE ACTIVITY OVER THE CWA TODAY. HOWEVER...DO
EXPECT SOME CUMULUS TO BUILD OVER THE HILLS ESPECIALLY IN MONTEREY
COUNTY.

SOME ELEVATED INSTABILITY IS PRESENT OVER SOUTHERN MONTEREY COUNTY
TOMORROW AFTERNOON AS THE LOW SLIDES EAST. HOWEVER 1200 UTC NAM12
PROXIMITY SOUNDINGS ARE STILL SHOWING A LACK OF SIGNIFICANT MOISTURE
OVER THE AREA. THEREFORE...ELEVATED CONVECTION IS NOT EXPECTED OVER
THE CWA AS THE LOW CONTINUES TO SLIDE EAST TOMORROW.

CURRENT MODEL SOLUTIONS INDICATE HIGH PRESSURE BUILDING OVER THE
EASTERN PACIFIC FRIDAY AS THE LOW SLIDES INTO THE GREAT BASIN. THE
1200 UTC NAM12 SHOWS A THERMAL TROUGH BUILDING OVER CALIFORNIA WITH
OFFSHORE WINDS DEVELOPING FRIDAY NIGHT INTO SATURDAY. THIS WILL
RESULT IN LESS STRATUS ALONG THE COAST AND A SIGNIFICANT WARM UP
INLAND FOR THE WEEKEND.

THE WARM UP WILL BE SHORT LIVED WITH BOTH THE 1200 UTC GFS AND
0000 UTC ECMWF SHOWING A TROUGH PUSHING INTO THE PACIFIC NORTHWEST
SUNDAY AFTERNOON. THIS WILL FLATTEN THE RIDGE AND INDUCE ONSHORE
FLOW ALONG COASTAL CALIFORNIA. THE ONSHORE FLOW WILL USHER IN
ANOTHER ROUND OF STRATUS AND COOLER TEMPERATURES FOR THE BEGINNING
OF THE WORK WEEK.

&&

.AVIATION...AS OF 10:41 AM WEDNESDAY...SOUTHERLY FLOW HAS KEPT
WIDESPREAD CIGS ALONG THE COAST AND IN MRY BAY...BUT HAS LITTLE
INFLUENCE OVER SF BAY.  THERE WAS A BRIEF CIG OVER THE APPROACH...
BUT LATEST SATELLITE SHOWS THAT IT HAS ALL DISSIPATED.

VICINITY OF KSFO...VFR CONDITIONS THIS AFTERNOON WITH LOW CIGS POSS
NEAR THE GAP.  WINDS MAY BE A LITTLE GUSTY THIS AFTERNOON AS THE
ONSHORE GRADIENT IS FORECAST TO BE GREATER THAN 3-4MB. FOR
TONIGHT...ONSHORE FLOW REMAINS AND A MORE DEFINED MARINE LAYER WILL
EXIST.  ENTRANCE OF STRATUS WILL BE SOMEWHAT DELAYED...BUT MOSTLY
LIKELY FILL IN AFTER 7Z AT 1000-1500 FEET.

KSFO BRIDGE APPROACH...SIMILAR TO SFO...BUT CIGS MAY BE DELAYED
ANOTHER HOUR OR TWO AFTER FILLING OVER THE AIRPORT.

MONTEREY BAY TERMINALS...LOW CIGS REMAIN AOB 1K FT. RECENT TRENDS
SHOW THAT STRATUS IS GRADUALLY CLEARING BACK TO THE COAST.  KSNS
WILL LIKELY SCT OUT FIRST FOLLOWED BY KMRY.  CONF IS LESS FOR
SUBSTANTIAL CLEARING AT KMRY BUT FOR NOW WILL ALLOW FOR A FEW HOURS
OF SCT CIGS THIS AFTERNOON. EARLY RETURN TONIGHT SHORTLY AFTER 00Z.
