AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
1000 AM PST WED NOV 9 2011

.SYNOPSIS...
HIGH PRESSURE WILL DOMINATE THE CENTRAL CALIFORNIA REGION INTO
THURSDAY. TODAY AND THURSDAY EARLY MORNING PATCHY DENSE FOG CAN BE
EXPECTED. A STORM SYSTEM WILL BEGIN TO MOVE INTO THE AREA BY
THURSDAY NIGHT AND LAST THROUGH THE WEEKEND.

&&

.DISCUSSION...LITTLE CHANGE IN THE OVERALL PATTERN SINCE YESTERDAY
WITH 50H RIDGE OVER CA. SFC OBS AND SATELLITE IMAGERY REVEAL NOTHING
MORE THAN A FEW PATCHES OF FOG IN THE SJ VLY. WITH THE EXCEPTION OF
HANFORD...VISIBILITIES AT MOST LOCATIONS ARE GENERALLY 3 MILES OR
BETTER AT THIS TIME. THE NORMALLY COLDEST SPOTS OF THE SJ VLY GOT
NIPPED BY SOME FROST THIS MORNING. BEFORE DAYBREAK...THE TEMPERATURE
BRIEFLY DROPPED TO 28 DEGREES AT THE HANFORD AIRPORT AND 29 DEGREES
AT ALLENSWORTH STATE PARK. COLLINS CORNER REPORTED A LOW TEMP OF 31
DEGREES. MIN TEMPS ELSEWHERE IN THE SJ VLY WHERE GENERALLY BETWEEN
33 AND 40 DEGREES.

OVER THE MOUNTAINS...HOWEVER...TEMPS ARE TRENDING A GOOD 3 TO 7
DEGREES
WARMER THIS MORNING THAN 24 HRS AGO WITH THE INVERSION SITTING AT
ABOUT 2K FEET. OTHER THAN SOME CIRRUS...AMPLE SUNSHINE IS EXPECTED
ACROSS THE CWA TODAY WITH TEMPS RECOVERING TO SEASONABLE LEVELS THIS
AFTERNOON. OTHERWISE...AN OFFSHORE FLOW WILL PREVAIL OVER CENTRAL CA
THROUGH THURSDAY AS A SURFACE HIGH REMAINS SITUATED OVER THE GREAT
BASIN. THE OFFSHORE FLOW WILL STRENGTHEN DURING THE NEXT 24 HOURS...
HOWEVER AS THE UPPER LEVEL RIDGE MOVES EASTWARD AND A STORM OVER THE
EASTERN PACIFIC BEGINS TO DRIFT TOWARD THE CA COAST. THIS WILL LIKELY
INTENSIFY EASTERLY WINDS THROUGH THE CANYONS AND PASSES OF KERN
COUNTY AND BRING DOWNSLOPE WINDS INTO THE SOUTH END OF THE SJ VLY BY
TONIGHT. ONCE ESTABLISHED...THESE DOWNSLOPE WINDS WILL LIKELY
PERSIST THROUGH MIDDAY FRIDAY...PERHAPS GUSTING TO 50 MPH OR MORE AT
THE FOOT OF THE GRAPEVINE THE NEXT TWO NIGHTS. AT THE VERY LEAST...A
WIND ADVISORY IS WARRANTED TO ADDRESS THIS CONCERN. WHATEVER THE CASE...
IT WOULD NOT BE A SURPRISE IF TEMPS SUDDENLY JUMPED SEVERAL DEGREES
AND RELATIVE HUMIDITIES DROPPED SHARPLY AT THE SOUTH END OF THE SJ
VLY TONIGHT AND THESE AREAS REMAINED RELATIVELY MILD AND DRY THROUGH
FRIDAY.

THE ADVERTISED END OF THE WEEK STORM DOES NOT LOOK LIKE IT WILL BE
THE ANIMAL IT WAS ONCE PROGGED TO BE A COUPLE DAYS AGO. ALTHOUGH
CONFIDENCE IS LOW AS TO HOW MUCH PRECIP THIS SYSTEM BRINGS TO THE
CENTRAL CA INTERIOR FROM LATE FRIDAY INTO SATURDAY...WE CAN AT LEAST
BANK ON A RATHER CLOUDY END TO THE WEEK. THE MODELS ARE TRACKING THE
OFFSHORE STORM AND THE BULK OF ITS MOISTURE INTO SOUTHERN CA BY THEN
WHILE ANOTHER FEATURE IN THE NORTHERN BRANCH OF THE JET STREAM MOVES
THROUGH NORTHERN CA. THIS WOULD LEAVE MUCH OF CENTRAL CA IN A SPLIT
FLOW PATTERN WITH MEAGER AMTS OF PRECIP. LATEST QPF FROM THE MODELS
AND FROM THE CNRFC AND HPC SUGGEST PRECIP AMTS WILL BE NOMINAL AT
BEST AND MAINLY OVER THE MOUNTAINS FROM LATE FRIDAY INTO SATURDAY.

BEYOND SATURDAY AND AT LEAST THROUGH NEXT WEDNESDAY...A DRY NORTHWEST
FLOW ALOFT WILL PREVAIL OVER CA WITH TEMPS AVERAGING PRETTY CLOSE TO
NORMAL.

&&

.PREV DISCUSSION... /ISSUED 422 AM PST WED NOV 9 2011/

DISCUSSION...SHORTWAVE RIDGING IS PUSHING IN OVER CA THIS
MORNING. TEMPS TODAY WILL WARM SEVERAL DEGS MORE OVER YESTERDAY
WITH SUNNY SKIES. AN INCREASING SOUTHERLY FLOW AT THE SURFACE AND
ALOFT WILL HELP PUSH TEMPS TO SLIGHTLY ABOVE NORMAL THURS. WEAK
DOWNSLOPE WARMING COULD PUSH TEMPS TO NEAR 80 IN THE SOUTH END OF
THE VALLEY. LOCALLY GUSTY SE-S WINDS MAY DEVELOP OVER THE KERN
COUNTY MTNS THURS AFTERNOON...AND MAY REQUIRE AN ADVISORY.
HOWEVER MODELS ARE TRENDING FARTHER WEST AND SOUTH WITH THIS SYS
THAN PREV MODEL RUNS. CONFIDENCE AT THIS TIME IS NOT HIGH ENOUGH
TO ISSUE AN ADVISORY.

A DEEP LONGWAVE TROF IN THE EAST PAC ALONG 140W IS BEGINNING TO
CLOSE OFF/CUTOFF AS IT TRACKS SLOWLY EAST. MODELS BRING THE
CUTOFF LOW TOWARD THE CENTRAL CA COAST FRI. THERE IS STILL
CONSIDERABLE DIFFERENCE BETWEEN THE ECMWF AND GFS WITH REGARD TO
PRECIP OVER THE CENTRAL CA INTERIOR. EXPERIENCE HAS SHOWN MANY
TIMES THAT COASTAL HUGGERS DONT...AS A RULE...YIELD MUCH IN THE
WAY OF PRECIP EAST OF THE COAST RANGES.

HOWEVER THE SYSTEM DOES HAVE A NARROW BAND OF SUBTROP MOISTURE
STILL FEEDING INTO THE COLD FRONT...AND I SEE NO REASON THIS WILL
BE SHUT OFF. BEST CHANCE OF PRECIP WILL BE ALONG AND AHEAD OF THE
TROF AXIS LATER FRI INTO FRI NITE. RAISED POPS MOST AREAS FOR FRI
AND FRI NITE AS THE DEFORMATION MOVES THRU. QPF AMOUNTS WITH THIS
SYS WILL BE HIGHEST NEAR THE WESTERN FOOTHILLS OF THE VALLEY FRI
SPREADING INTO THE TEHACHAPI MTNS FRI NITE.

SNOW LEVELS WITH THIS SYSTEM WILL REMAIN RELATIVELY HIGH FOR THIS
TIME OF YEAR...AS COLDEST AIR REMAINS WELL OFFSHORE. DONT EXPECT
MUCH IF ANY ACCUMULATING SNOW BELOW ABOUT 7000 FT. AND WITH VERY
LOW QPF AMOUNTS IN THE SRN SIERRA...NO WINTER HEADLINES ARE
ANTICIPATED. SOME MODERATE TO BRIEFLY HEAVY RAINFALL COULD OCCUR
IN THE TEHACHAPIS FRI NITE...OTHERWISE ONLY LIGHT AMOUNTS OF
PRECIP ARE EXPECTED.

THE UPPER LOW WILL BEGIN TO OPEN UP AS IT PROGRESSES EAST
SAT...WITH THE MAIN UPPER LOW AND TROF AXIS CROSSING OVER BAJA
INTO ARIZONA BY SUNDAY MORNING. PRECIP WILL DIMINISH FROM NORTH TO
SOUTH SAT AND BE MOSTLY ENDED LATE SAT NITE. A FEW LINGERING
SHOWERS MAY PERSIST OVER THE MTNS SUN...OTHERWISE DRY.
MODELS SHOW A PERSISTENT NW FLOW ALOFT ACROSS CA WELL INTO NEXT
WEEK. OVERALL MODELS INDICATE AT DRY FCST WITH ONLY MINOR DAY TO
DAY FLUCTUATIONS IN TEMPS. EMBEDDED SHORTWAVE TROFS IN THE FLOW
WILL BRING SOME CLOUDS FROM TIME TO TIME FOR A PTCLDY FCST.

&&
