AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
845 PM PST SAT JAN 1 2011

.SYNOPSIS...
VALLEY RAIN AND HIGHER ELEVATION SNOW EXPECTED OVER THE WEEKEND.
HIGH PRESSURE TAKES OVER BY MID WEEK, PRODUCING CLEAR SKIES WITH
PATCHY MORNING FOG AND SLIGHTLY WARMER TEMPERATURES FOR THE SAN
JOAQUIN VALLEY.

&&

.DISCUSSION...
SATELLITE LOOPS SHOW THE UPPER-LEVEL LOW NEAR 38N/128W...WEST OF THE
NORTHERN CALIFORNIA COAST. THE LOW HAS BEEN SPINNING LIGHT TO
MODERATE PRECIPITATION INTO THE CENTRAL CALIFORNIA INTERIOR...MAINLY
FROM FRESNO COUNTY SOUTH AT THIS TIME. BY 03Z SUNDAY /200 PST
SATURDAY/...THE VISALIA MUNICIPAL ALREADY HAD RECEIVED 0.20 INCH OF
RAIN.

SPOTTER...CHP AND MEDIA REPORTS INDICATE THAT SNOW IS FALLING DOWN
TO AROUND 2700 FEET IN THE KERN COUNTY MOUNTAINS...AND STICKING AT
THE 3000 FOOT LEVEL. THE SNOW LEVELS HAVE LOWERED FASTER THAN
ANTICIPATED...AND HAVE UPDATED THE FORECAST TO REFLECT LOWER SNOW
LEVELS TONIGHT AND SUNDAY.

SATELLITE LOOPS SHOW THE SUBTROPICAL MOISTURE FETCH ASSOCIATED WITH
THIS SYSTEM TO BE LESS ORGANIZED THAN 24 HOURS EARLIER. HOWEVER...THE
NEW 00Z NAM STILL FORECASTS A QPF FOR FRESNO OF 1.16 INCH...1.33
INCH FOR MERCED...AND 1.73 INCH FOR YOSEMITE VALLEY. THE NAM ALSO
FORECASTS A QPF FOR GIANT FOREST OF 3.61 INCHES...NEARLY ALL OF
WHICH SHOULD FALL AS SNOW FOR AN ACCUMULATION OF AROUND 3 FEET. THE
NAM FORECASTS THE HEAVIEST PRECIPITATION TO FALL FROM 06Z SUNDAY TO
06Z MONDAY /2200 PST SATURDAY-2200 PST SUNDAY/...SO THE TIMING OF
THE WINTER STORM WARNINGS AND THE FLOOD WATCHES LOOK TO BE ON TRACK.

SPC HAS THE FAR WEST SIDE OF THE SAN JOAQUIN VALLEY /WEST OF THE
INTERSTATE 5 CORRIDOR/ UNDER A GENERAL RISK OF THUNDERSTORMS. THE
NEW NAM-12 KEEPS SURFACE-BASED CAPE WEST OF THE HANFORD WARNING/
FORECAST AREA...AND SURFACE-COMPUTED LIFTED INDEXES OVER THE CENTRAL
AND SOUTHERN SAN JOAQUIN VALLEY REMAIN POSITIVE. THERE IS A SLIGHT
CHANCE THAT A COASTAL THUNDERSTORM MAY DRIFT OVER THE TEMBLORS OR
DIABLO RANGE...BUT ANY ORGANIZED CONVECTION SHOULD REMAIN WEST OF
THE CENTRAL CALIFORNIA INTERIOR.

&&

.PREV DISCUSSION... /ISSUED 324 PM PST SAT JAN 1 2011/
WATER VAPOR SATELLITE IMAGERY SHOWS THE UPPER LOW MOVING SOUTHEAST
TO JUST INSIDE OF 40N/130W OFF THE NORCAL COAST THIS AFTERNOON. A
HEALTHY PLUME OF MOISTURE ALONG WITH UPPER DIFLUENCE HAS LED TO AN
OUTBREAK OF SHOWERS OVER CENTRAL CALIFORNIA AND THIS ACTIVITY
SHOULD INCREASE THROUGH THE NIGHT AS THE LOW GRADUALLY SLIDES
SOUTHEAST. HAVE UPGRADED THE WINTER STORM WATCH FOR THE SOUTHERN
SIERRA NEVADA TO A WARNING BEGINNING AT MIDNIGHT TONIGHT. QPF FOR
THE SIERRA NEVADA RANGES FROM 1.5 TO 2.5 INCHES FOR THE POTENTIAL
OF AROUND A FOOT OF SNOWFALL AROUND 5000 FEET AND AS MUCH AS 3
FEET OF SNOW OVER THE HIGH COUNTRY. THE WATCH FOR THE KERN COUNTY
MOUNTAINS HAS ALSO BEEN UPGRADED TO A WARNING BEGINNING AT NOON
SUNDAY...WITH UP TO 1 INCH QPF FORECAST. THE SNOW LEVEL IS
EXPECTED TO BE LESS THAN 3000 FEET AT TIMES SO THE WARNING WAS
ISSUED FOR ELEVATIONS ABOVE 2000 FEET. THIS WILL RESULT IN
ACCUMULATING SNOWFALL WELL DOWN TO PASS LEVELS FOR THE END OF THE
HOLIDAY WEEKEND LEADING TO HAZARDOUS TRAVEL CONDITIONS. A COLD
NORTHEAST SURFACE FLOW INTO THE HIGH DESERT HAS RESULTED IN A VERY
CHILLY DAY TODAY WITH TEMPERATURES MAINLY IN THE UPPER 30S. THIS
COLD AIRMASS HAS WARRANTED THE ISSUANCE OF A WINTER STORM WATCH
FOR THE KERN COUNTY DESERTS FROM SUNDAY AFTERNOON THROUGH MONDAY
AFTN WITH THE SNOW LEVEL AROUND 2500 FEET. QPF AROUND A HALF INCH
SUGGESTS FROM 4 TO 8 INCHES OF SNOW ABOVE 3000 FEET AND PERHAPS 2
TO 5 INCHES DOWN THE DESERT FLOOR. AGAIN...POTENTIALLY MAKING FOR
VERY HAZARDOUS TRAVEL CONDITIONS. SAN JOAQUIN VALLEY RAINFALL IS
EXPECTED TO BE FROM 0.5 TO 1 INCH WITH 1-2 INCHES INTO THE
FOOTHILLS. GIVEN THE STILL SATURATED GROUND IN MANY AREAS...A
FLOOD WATCH IS IN EFFECT FROM 6 PM TONIGHT THROUGH LATE SUNDAY
NIGHT. THE LOW IS PROGGED TO STRADDLE THE CENTRAL CALIFORNIA COAST
SUNDAY AFTERNOON BRINGING A SLIGHT THREAT OF THUNDERSTORMS TO
MAINLY COASTAL AREAS. BUT THIS NEEDS TO BE WATCHED IN CASE THE LOW
WERE TO SHIFT A LITTLE FARTHER INLAND FOR INCREASED INSTABILITY
OVER OUR AREA. THE LOW IS SLOW TO EXIT WITH SHOWERS LIKELY TO
CONTINUE OVER THE KERN COUNTY MOUNTAINS AND DESERT ON MONDAY. SOME
MODEL UNCERTAINTY REMAINS BEYOND MONDAY BUT THE GENERAL IDEA IS
FOR A DRYING TREND AS A WEAK TROUGH/LOW SETTLES OVER SOCAL AND
RIDGING BUILDS IN TO THE NORTH FOR A QUASI REX BLOCK PATTERN.

&&

.AVIATION...
WIDESPREAD IFR IN MOUNTAIN OBSCURATIONS OVER THE SOUTHERN SIERRA
NEVADA AND TEHACHAPI MOUNTAINS. ELSEWHERE MAINLY VFR WITH AREAS OF
MVFR IN CLOUDS AND PRECIPITATION THROUGH 06Z MONDAY.

&&

.AIR QUALITY ISSUES...
NONE.

&&
