AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
238 PM PDT THU NOV 3 2011

.SYNOPSIS...
AN APPROACHING FRONTAL SYSTEM WILL MOVE THROUGH THE AREA THIS
EVENING WITH INCREASING CLOUDS AND A CHANCE OF RAIN SHOWERS TO THE
VALLEY AND MOUNTAIN SNOW SHOWERS THROUGH FRIDAY. ANOTHER ROUND OF
SHOWERS IS POSSIBLE IN THE AREA LATE SATURDAY NIGHT AND SUNDAY. MUCH
COOLER THAN AVERAGE TEMPERATURES ARE EXPECTED FRIDAY THROUGH EARLY
NEXT WEEK.

&&

.DISCUSSION...DELIGHTFUL FALL WEATHER IS UPON US THIS AFTERNOON...
BUT A COLD FRONT WILL COME ALONG AND USHER IN A WINTRY CHANGE BY
FRIDAY MORNING. THE COLD FRONT SHOWS UP QUITE WELL ON THE LATEST
SATELLITE IMAGERY...STRETCHING FROM SPOKANE TO NEAR REDDING THIS
AFTERNOON. ALTHOUGH MOISTURE WITH IT IS RATHER LIMITED...IT WILL
BRING SOME SHOWERS TO MUCH OF THE CWA WITH THE EXCEPTION OF THE
KERN COUNTY DESERT TONIGHT. THE UPPER LOW ASSOCIATED WITH THIS
FRONT IS STILL CENTERED ABOUT 500 MILES OR SO OFF THE OREGON COAST
AND IT...TOO...WILL TRACK SOUTHEASTWARD AND BE DIRECTLY OVER THE
CENTRAL CA INTERIOR FRIDAY AFTERNOON. SATELLITE IMAGERY SHOWS
PLENTY OF CELLULAR LOOKING CUMULUS UNDERNEATH THIS LOW WHICH IS
INDICATIVE OF VERY COLD AIR ALOFT. AS THE UPPER LOW APPROACHES
FROM THE NORTHWEST LATER TONIGHT...THE WEST SLOPES OF THE SIERRA
MAINLY NORTH OF KINGS CANYON WILL BE IN A REGION OF VERY FAVORABLE
OROGRAPHICS THANKS TO THE COMBINATION OF A 120+ JET AND STRONG
COLD ADVECTION. THE MODELS ARE ALSO SLOWING THIS SYSTEM DOWN A BIT
AND GENERATING SLIGHTLY HIGHER QPF AS A RESULT...AT LEAST HIGH
ENOUGH TO WARRANT THE ISSUANCE OF A WINTER WEATHER ADVISORY NORTH
OF KINGS CANYON FOR TONIGHT. (FOR DETAILS...PLEASE SEE THE LATEST
SFOWSWHNX...WWUS46)

MUCH OF THE WEST SIDE AND SOUTH END OF THE SJ VLY WILL BE RAIN
SHADOWED UNTIL THE COLD FRONT PASSES AND WINDS TURN INTO THE NW.
THIS MAY NOT HAPPEN UNTIL THE PREDAWN HOURS FRIDAY. IN ITS WAKE...
TEMPERATURES WILL NOT LIKELY RECOVER VERY MUCH AS COLDER AIR
POURS INTO THE REGION. NUMEROUS SHOWERS WILL LINGER OVER THE
MOUNTAINS FRIDAY AFTERNOON BUT BECOME MORE ISOLATED OVER THE
LOWER ELEVATIONS. IN ADDITION...TEMPERATURES THROUGHOUT THE CENTRAL
CA INTERIOR WILL BE A GOOD 10 TO 20 DEGREES COLDER FRIDAY AFTERNOON
COMPARED TO TODAY.

SHOWERS WILL DIMINISH OVER THE MOUNTAINS BY FRIDAY EVENING AS THE
UPPER LEVEL TROUGH EXITS INTO THE GREAT BASIN. YET...LOW CLOUDS
WILL LIKELY LINGER ALONG THE WEST SLOPES OF THE SIERRA...THE NORTH
FACING SLOPES OF THE TEHACHAPI MOUNTAINS AND THE EAST SIDE AND
SOUTH END OF THE SJ VLY THROUGH AT LEAST SATURDAY MORNING.
OTHERWISE...SHORT WAVE RIDGING ALOFT WILL BRING US A BREAK FROM
WET WEATHER SATURDAY WITH TEMPERATURES REMAINING WELL BELOW NORMAL.

IN THE MEANTIME...ANOTHER UPPER LEVEL TROUGH WILL APPROACH FROM
THE NORTHWEST. THIS NEXT SYSTEM LOOKS AS THOUGH IT WILL BE A BIT
WETTER BUT NOT QUITE AS COLD AND BRING ANOTHER ROUND OF SNOW TO
THE HIGHER ELEVATIONS OF THE SIERRA WITH A GOOD CHANCE OF SHOWERS
ELSEWHERE SATURDAY NIGHT AND SUNDAY.

DRY WEATHER AND A MODEST WARMING TREND IS SLATED FOR EARLY NEXT
WEEK AS AN UPPER LEVEL RIDGE BUILDS OVER CA. BEYOND TUESDAY...
THE MODELS ARE POLARIZED AND CONFIDENCE IS VERY LOW AS TO WHAT WILL
HAPPEN. IF THE GFS IS RIGHT...ANOTHER UPPER LEVEL TROUGH WILL BRING
A RETURN OF WET AND UNSEASONABLY COOL WEATHER TO THE CENTRAL CA
INTERIOR DURING THE MIDDLE OF NEXT WEEK. ON THE OTHER HAND...THE
ECM FORECASTS AN UPPER LEVEL RIDGE OF HIGH PRESSURE TO REMAIN OVER
CA WITH A CONTINUATION OF DRY WEATHER AND MILDER THAN NORMAL TEMPS.
UNTIL THE MODELS COME INTO BETTER AGREEMENT...WE ARE FAVORING THE
MORE RELIABLE ECM SOLN.

&&

.AVIATION...
AN APPROACHING STORM SYSTEM WILL SPREAD SCATTERED SHOWERS FROM
AROUND YOSEMITE AFTER 00Z FRI SOUTHWARD THROUGH THE KERN COUNTY
MOUNTAINS BY 12Z FRI...PRODUCING AREAS OF MVFR CONDITIONS ALONG
WITH LOCAL IFR IN MOUNTAIN OBSCURATIONS OVER THE SOUTHERN SIERRA
NEVADA AND TEHACHAPI MOUNTAINS. VFR CONDITIONS WILL OTHERWISE
PREVAIL ACROSS THE CENTRAL CA INTERIOR THRU 18Z FRI.
