AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
1018 AM PDT FRI OCT 5 2012

.SYNOPSIS...
AN AREA OF LOW PRESSURE MOVING TOWARDS CENTRAL CALIFORNIA WILL
PRODUCE COOLING TEMPERATURES AND VARIABLE CLOUDS TO THE AREA.

&&

.DISCUSSION...TEMPERATURES ARE CERTAINLY COOLER THROUGHOUT
MUCH OF THE CENTRAL CA INTERIOR COMPARED TO 24 HRS AGO. THE
MOST DRAMATIC COOLING SINCE YESTERDAY HAS OCCURRED OVER THE
MOUNTAINS WHERE 24-HR TRENDS OF -9 TO -11 DEGREES HAVE BEEN
REPORTED. ALTHOUGH ONSHORE GRADIENTS ARE MODEST AT BEST...
THEY ARE STRONG ENOUGH TO SUPPORT WIND GUSTS TO MARGINALLY
ADVISORY THRESHOLDS THROUGH AND JUST BELOW THE KERN COUNTY
MOUNTAIN PASSES LATER TODAY THROUGH TONIGHT. AFTER FURTHER
ASSESSMENT...WE WILL CONSIDER LAUNCHING A WIND ADVISORY FOR
THESE AREAS IN THE NEXT FORECAST PACKAGE.

IN THE BROADER PICTURE...A VERY STRONG REX BLOCK IS IN PLACE
OVER THE EASTERN PACIFIC. THE MODELS FORECAST VERY LITTLE
CHANGE IN THIS BLOCKING PATTERN THROUGH THE WEEKEND. DURING
THIS TIME...A DRY SOUTHWESTERLY FLOW ALOFT WILL PREVAIL OVER
CENTRAL CA AND BRING NOTHING MORE THAN SOME CIRRUS INTO THE
CENTRAL CA INTERIOR. IN THE LOW LEVELS...A MODEST ONSHORE FLOW
WILL PERSIST THROUGH THE WEEKEND AND FEED MARINE AIR INTO THE
SJ VLY AND LOWER FOOTHILLS.

THE MODELS FORECAST THE REX BLOCK TO WEAKEN BUT NOT UNTIL
MONDAY...A TIME WHEN THE CLOSED LOW WITHIN THIS BLOCK BEGINS
TO DRIFT TOWARD THE CENTRAL CA COAST. THE MODELS ARE MUCH
SLOWER BRINGING THIS LOW INLAND ACROSS THE CENTRAL CA INTERIOR
AND HAVE NOW DELAYED ITS ARRIVAL UNTIL LATE TUESDAY NIGHT OR
WEDNESDAY. THAT BEING THE CASE...DRY WEATHER WILL PROBABLY
CONTINUE OVER THE CENTRAL CA INTERIOR THROUGH MONDAY AND PERHAPS
WELL INTO MONDAY NIGHT. ULTIMATELY...OUR WEATHER WILL BECOME
MORE UNSETTLED AS THE CLOSED LOW COMES ASHORE. CURRENT THINKING
IS THAT THE GREATEST CONVECTIVE POTENTIAL WITH THIS COLD CORE
LOW WILL OCCUR BETWEEN MIDDAY TUESDAY AND WEDNESDAY EVENING.
DURING THIS TIME...ISOLATED SHOWERS ARE POSSIBLE IN THE SJ VLY
WITH MORE NUMEROUS SHOWERS OVER THE HIGHER TERRAIN. SNOW LEVELS
COULD LOWER TO AROUND 7500 FEET IN THE SIERNEV BY WED MORNING.
OTHERWISE...TUESDAY AND WEDNESDAY WILL BE UNSEASONABLY COOL...
PERHAPS NO WARMER THAN 70 DEGREES IN THE SJ VLY.

THE EXTENDED MODELS FORECAST THE UPPER LEVEL LOW TO MEANDER
OVER CENTRAL OR SOUTHERN CA AFTER MIDWEEK. IF SO...OUR WEATHER
PATTERN WILL REMAIN UNSETTLED AND MUCH COOLER THAN NORMAL
THROUGH AT LEAST NEXT FRIDAY.

&&

.PREV DISCUSSION... /ISSUED 151 AM PDT FRI OCT 5 2012/

DISCUSSION...FORECAST AREA REMAINS UNDER THE APEX OF A WEAK RIDGE
THIS MORNING AS AN UPPER LEVEL VORTICITY CENTER PASSES TO THE
NORTH. MID AND HIGH CLOUDS HAVE DEVELOPED IN THIS AREA OF ENHANCED
LIFT OVER AND NORTH OF THE BAY AREA BUT THAT IS ABOUT IT. THE
OVERALL PATTERN OVER THE EAST PACIFIC STILL REMAINS RATHER STEADY
WITH THE LARGE LOW SPINNING OUT NEAR 35/135W IN A REX BLOCK
PATTERN. FOR TODAY THROUGH THE WEEKEND THE WEATHER WILL BE
DOMINATED BY DRY AND SLIGHTLY COOLER WEATHER AS THE EXTREME HEAT
OF LATE STUBBORNLY GIVES WAY TO COOLER AIR FROM THE PACIFIC. FOR
SUNDAY, FORECAST MODELS BRING THE ABOVE MENTIONED LOW CLOSER TO
THE CALIFORNIA COAST BUT BASED ON THE LATEST PROJECTED POSITION IT
SHOULD STAY FAR ENOUGH WEST TO KEEP THE INTERIOR OF CENTRAL
CALIFORNIA DRY.

NEXT WEEK THINGS GET MORE INTERESTING AS FORECAST MODELS CONTINUE
TO BRING THE CENTER OF LOW PRESSURE INTO AND ACROSS CENTRAL
CALIFORNIA MONDAY AND TUESDAY, STALLING OUT THIS FEATURE WEDNESDAY
AND THURSDAY. ONE THING IS FOR SURE, IT WILL BE MUCH COOLER. AS
FOR PRECIPITATION CHANCES, I HAVE TRIED TO PIN DOWN THE AREA OF
GREATEST CHANCE FOR MONDAY AND MONDAY NIGHT BUT STILL HAVE NOT
INCREASED RAIN CHANCES ABOVE 25%. FOR THE REMAINDER OF THE WEEK,
THE SLIGHT CHANCE POPS LOOK REASONABLE DUE TO MOISTURE
AVAILABILITY WITH THE CYCLONE.
