AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1036 PM PDT MON OCT 10 2011
.DISCUSSION...AS OF 8:31 PM PDT MONDAY...A WEAKENING COLD FRONT
CONTINUES TO SLIDE SOUTHEAST THROUGH THE FORECAST AREA THIS
EVENING. CURRENT AMSU TPW IMAGE INDICATES THAT TPW VALUES ARE 1.77
INCHES ALONG THE CENTRAL CALIFORNIA COAST. OBSERVATIONS UP AND
DOWN THE CENTRAL COAST ARE SHOWING DEW POINTS FROM 16 TO 17
DEGREES CELSIUS WHICH IS PROVIDING A HUMID FEEL TO THE AIR THIS
EVENING AND WILL HELP TO MAINTAIN WARM OVERNIGHT TEMPERATURES. THE
HIGH DEW POINTS WILL ALSO RESULT IN PATCHY COASTAL FOG. LIGHT
ONSHORE FLOW AHEAD OF THE COLD FRONT AND THE DEEP MOISTURE
PREVIOUSLY MENTIONED WILL KEEP A SLIGHT CHANCE OF LIGHT SHOWERS
OVERNIGHT. THIS THREAT WILL DIMINISH BY SUNRISE AS HIGH PRESSURE
BEGINS TO FILL IN BEHIND THE COLD FRONT.
PREVIOUS DISCUSSION...DRIER WEATHER RETURNS ON TUESDAY AND
CONTINUES AT LEAST THROUGH ALL OF THURSDAY AS A RIDGE OF HIGH
PRESSURE BUILDS INTO OUR AREA ALOFT. AT THE SAME TIME THE SURFACE
PRESSURE GRADIENT WILL SWITCH FROM MORE NORTHWESTERLY TO
NORTHERLY/NORTHEASTERLY BY WEDNESDAY. THESE TWO FACTORS WILL
COMBINE WITH WARMING TEMPERATURES AT 850 MB TO BRING WARMER
WEATHER TO OUR ENTIRE REGION. EVEN MOST COASTAL SPOTS COULD HIT
THE 70S. 80S TO LOWER 90S ARE POSSIBLE ON THURSDAY.
STILL A LOT OF UNCERTAINTY FOR LATE FRIDAY THROUGH THE UPCOMING
WEEKEND AS THE ECMWF BRINGS A SHARP LONGWAVE TROF TO THE COAST ON
SATURDAY. THE GFS CONTINUES TO REMAIN 100% DRY WITH THE TROF
SPLITTING AND A LARGE PORTION OF THE ENERGY RETROGRADING. WITH
THIS DISAGREEMENT ALONG WITH A MODERATE TO LARGE ENSEMBLE SPREAD
POPS WERE KEPT UNDER 30%.
