AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
242 PM PST MON NOV 23 2009
.SYNOPSIS...SKIES WILL GENERALLY BE CLEAR EXCEPT PATCHY FOG OVER
THE SAN JOAQUIN VALLEY MAY DEVELOP LATER TONIGHT INTO THE MORNING
HOURS. A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE AREA FOR THE
NEXT FEW DAYS PRODUCING DRY CONDITIONS AND GRADUAL WARMING. A
TROUGH WITH LITTLE MOISTURE ASSOCIATED WITH IT IS PROGGED TO PASS
THROUGH THE AREA ON FRI THRU THE REST OF THE WEEKEND COOLING
TEMPS BACK DOWN A LITTLE.
&&
.DISCUSSION...
STRATUS DECK HAS ALMOST ENTIRELY DISSIPATED OVER THE VALLEY AT
THIS TIME. DUE TO A SMALL AREA OF LOW CLOUDS THAT REMAINS NEAR
MERCED TEMPS HAVE BEEN SLOWEST TO RECOVER THERE. OTHERWISE TEMPS
THROUGHOUT THE VALLEY ARE GENERALLY AROUND THE SAME AS THEY WERE
24 HRS AGO. THE REST OF THE FCST AREA IS GENERALLY AT LEAST A FEW
DEG WARMER WITH MOSTLY CLEAR SKIES...WITH GREATEST WARMING IN THE
MTNS AND FOOTHILLS...COMPARED TO 24 HRS AGO DUE TO A LACK OF CLOUD
COVER FOR THE DAY. NOW THAT WE HAVE GENERALLY CLEAR SKIES AND
LIGHT WINDS...THE POSSIBILITY OF PATCHY FOG OVER THE VALLEY REMAINS
FOR LATE TONIGHT AND TUE AM.
THE RIDGE OF HIGH PRESSURE OVER THE AREA IS EXPECTED TO CONTINUE
BUILDING AND BRING WARMING TEMPS TUE THRU THANKSGIVING DAY BEFORE
GIVING WAY TO A TROUGH ON FRI AND THE REMAINDER OF THE HOLIDAY
WEEKEND. FCST MODELS ARE IN FAIRLY GOOD AGREEMENT IN MOVING THE
RIDGE EAST OF THE AREA WITH A TROUGH OVER THE AREA THRU SUN WHILE
ANOTHER EAST PACIFIC RIDGE BUILDS OFF THE WEST COAST. MODELS
SOMEWHAT DIFFER ON MOVING THE TROUGH...THE EURO DEPICTS THIS
TROUGH MORE AS AN INSIDE SLIDER MOVING OVER THE GREAT BASIN.
ANYHOW...DRY WEATHER IS LIKELY TO CONTINUE WITH TEMPS COOLING BACK
TO SLIGHTLY BELOW NORMAL FOR FRI INTO SUN. BEYOND THE HOLIDAY
WEEKEND KEPT TEMPS NEAR CLIMO FOR NOW...DUE TO MORE MODEL
DISAGREEMENT ON PLACEMENT OF FEATURES.
&&
.AVIATION...
A FEW LOW CLOUDS LINGERING OVER THE SOUTH END OF THE SAN JOAQUIN
VALLEY THROUGH THIS EVENING WILL GENERALLY STAY WITHIN VFR RANGE.
AREAS OF MVFR WITH SOME LOCAL IFR IN BR/FG WILL DEVELOP OVER THE
VALLEY AFTER 04Z THIS EVENING...MOSTLY DISSIPATING BY 19Z TUESDAY.
OTHERWISE...VFR CONDITIONS WILL PREVAIL ACROSS THE CENTRAL
CALIFORNIA INTERIOR THROUGH 00Z WEDNESDAY.
