AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
930 AM PDT THU MAY 22 2008

.DISCUSSION...AS OF 9:30 AM THURSDAY...SHORT TERM CONCERN IS WINDS
TODAY AND THEN COOLER TEMPS AND SHOWER CHANCES OVER THE HOLIDAY
WEEKEND.

VERY BUSY THIS MORNING AS ALL EYES HAVE BEEN ON THE SUMMIT FIRE NEAR
THE LEXINGTON HILLS HEADING TO THE SOUTH.  GUSTY NORTHERLY WINDS ARE
CONTINUING THIS MORNING OVER MANY HIGHER ELEVATION SITES AND AREAS
PRONE TO DOWNSLOPING. CAUSE OF THIS IS VARIOUS GRADIENTS ARE STILL
HIGH WITH SFO-LAS REMAINING ROBUST AT OVER 12 MB. AT THE
SAME TIME...AN UNUSUALLY STRONG TROUGH OVERHEAD IS HELPING TO PRODUCE
STRONG NORTHERLY WINDS ALOFT. VISIBLE SATELLITE ALONG WITH RADAR
NICELY DEPICT THE SMOKE PLUME WHICH HAS MADE IT THROUGH THE ENTIRE
COASTAL AREA OF MONTEREY COUNTY.

FOR THE FORECAST...GUSTY WINDS ARE EXPECTED TO CONTINUE THROUGH THE
DAY TODAY AND INTO THE EVENING HOURS. HOWEVER...BASED ON ALL MODEL
GUIDANCE INCLUDING HIGH RESOLUTION WRF AND TREND OF GRADIENTS...IT
APPEARS THAT THE HIGHEST GUSTS WILL BE DURING THE MORNING HOURS AND
SLOWLY DIMINISH THROUGH THE DAY TODAY AND INTO THE EVENING HOURS.
THINGS WILL IMPROVE CONSIDERABLY BY TOMORROW AS THE GRADIENT AT THE
SURFACE CONTINUES TO DIMINISH. PROGGED NUMBERS SHOW SFO-LAS
GRADIENT OF UNDER 5 MB BY FRIDAY AFTERNOON. TEMPERATURES WILL REMAIN
BELOW NORMAL FOR THE NEXT COUPLE OF DAYS WITH HIGHS IN THE 60S ON
THE COAST AND 70S INLAND EXPECTED.

FOR THE WEEKEND...STILL LOOKS LIKE AN OUTSIDE CHANCE OF SHOWERS AS
ENERGY ROTATES THROUGH THE TROUGH. POP VALUES IN THE CURRENT PACKAGE
LOOK REASONABLE AND WITH QPF AMOUNTS FORECAST TO BE LIGHT...ANY
SHOWER ACTIVITY WILL LIKELY JUST SETTLE THE DUST AND NOT PROVIDE MUCH
IN THE WAY OF HYDRO RELIEF.
&&

.AVIATION...AS OF 5:00 AM PDT...WHILE LOW PRESSURE HAS BEEN DUG OUT
OVER THE GREAT BASIN STRONG NORTH WINDS CONTINUE ALOFT OVER THE
CENTRAL COAST AND S.F.BAY AREA. CAVU CONDITIONS PREVAIL BUT AREA
TERMINALS WILL CONTINUE WITH NW WIND AND SPEEDS OF 20KTS PLUS BY LATE
MORNING AND THROUGH THE AFTERNOON. FOR KSFO THE AIRPORT WEATHER
WARNING HAS BEEN ALLOWED TO EXPIRE BUT WEST WINDS TO 30KTS CAN BE
EXPECTED BY 19Z AND GUSTS TO 33KTS AFTER 21Z.

&&

.MARINE...AS OF 5:00 AM PDT...STRONG NORTH-SOUTH PRESSURE GRADIENTS
CONTINUING NORTH GALE FORCE WINDS WITH OCCASIONAL STORM FORCE GUSTS
OVER THE COASTAL WATERS AS THE JET-STREAM ALOFT CARVES OUT LOW
PRESSURE OVER THE GREAT BASIN. GALE WARNINGS FOR THE MONTEREY AND
S.F.BAYS HAVE BEEN LOWERED WITH SMALL CRAFT ADVISORIES POSTED IN
THEIR PLACE. WIND WAVES ON MONTEREY BAY ARE NOT EXPECTED TO BE AS
HIGH TODAY AS THE WIND FLOW ALONG THE COAST IS VEERING TO A MORE
NORTH-BY-NORTHWEST DIRECTION AND MONTEREY BAY IS A BIT MORE
PROTECTED BY THE CALIFORNIA COAST.

&&

.FIRE WEATHER...AS OF 9:45 AM PDT...GUSTY NORTHERLY WINDS WILL
CONTINUE TODAY WITH THE HIGHEST SPEEDS EXPECTED OVER HIGHER
TERRAIN AND LOCATIONS PRONE TO NORTHERLY DOWNSLOPING. WINDS WILL
BEGIN TO SLIGHTLY DIMINISH BY THIS EVENING AND BECOMING A BIT MORE
WESTERLY. MINIMUM RH VALUES OF 25 TO 35 PERCENT ARE FORECAST FOR
INLAND LOCATIONS WITH 40 TO 50 PERCENT NEAR THE COAST.
