AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
956 AM PST SUN JAN 2 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...RADAR SHOWS LOTS OF SHOWERS CONTINUING TO ROTATE
INLAND ACROSS THE CENTRAL CA INTERIOR. RAINFALL IN THE CENTRAL
SAN JOAQUIN VALLEY HAS RANGED FROM A HALF TO NEARLY AN INCH SO
FAR WITH SEVERAL PLACES IN THE SOUTHERN SIERRA FOOTHILLS RECEIVING
1-2" INCHES. THE SNOW LEVEL REMAINS AROUND 4K FEET IN THE SIERRA
BUT COLDER AIR FROM THE GREAT BASIN SURFACE HIGH HAS SNOW LEVELS
IN THE KERN COUNTY MOUNTAINS DOWN JUST BELOW 3K FEET...AS
CONFIRMED BY A SPOTTER REPORT OF SNOW IN LAKE ISABELLA (~2700').
THE HIGH DESERT HAS TEMPS IN THE LOWER TO MID 30S AND WITH A GOOD
DEW POINT DEPRESSION...FEEL THAT EVAPORATIVE COOLING WILL HELP
LOWER SNOW LEVELS DOWN TO THE DESERT FLOOR THIS AFTERNOON. A
WINTER STORM WATCH REMAINS IN EFFECT BUT AM LEANING TOWARDS
ISSUING A WINTER WX ADVISORY SHORTLY. WIDESPREAD PRECIP WILL
CONTINUE THROUGH AROUND 12Z MONDAY THEN GRADUALLY DIMINISH FROM
THE NORTH. OTHERWISE...STRONG SOUTHERLY FLOW AHEAD OF THE LOW
CONTINUES TO PRODUCE VERY GUST WINDS THROUGH THE GRAPEVINE WITH
GUSTS TO AROUND 65 MPH AT THE PEAK AND 45 MPH AT THE BASE (CHP
STATION). THE WINTER STORM WARNING FOR THE KERN MTNS AND A WIND
ADV FOR THE SOUTHEAST SJ VALLEY HIGHLIGHTS THESE CONDITIONS. ONE
OTHER NOTE...CNRFC HAS FORECAST THE MERCED RIVER AT STEVINSON TO
RISE TO ABOVE MONITOR STAGE OF 67 FEET TOMORROW AFTERNOON. HAVE
ISSUED A HYDROLOGIC STATEMENT /RVSUSJ/.

&&

.PREV DISCUSSION... /ISSUED 422 AM PST SUN JAN 2 2011/

DISCUSSION...STACKED LOW NEAR THE CENTRAL CA COAST WILL LINGER
THRU MUCH OF THE DAY. BAROCLINIC LEAF DEVELOPED NICELY OVERNITE
ACROSS THE INTERIOR...PRETTY MUCH AS DEPICTED ON THE EURO THE PAST
SEVERAL DAYS. STRONG UVM HAS ALREADY PRODUCED RAINFALL EXCEEDING
AN INCH IN PLACES. A SMALL PLUME OF 1 INCH TPW ASSOCIATED WITH THE
OCCLUDING FRONT ALONG THE COAST WILL BRING AN ADDITIONAL 1-2
INCHES OF RAIN TODAY...AND UPGRADED THE FLOOD WATCH TO A WARNING
FOR THE CENTRAL SJV AND ADJACENT FOOTHILLS BELOW 4K. RAIN HAS BEEN
LIGHTER OR YET TO START IN THE SOUTH VALLEY...AND LEFT THE FLOOD
WATCH UP FOR NOW. BUT HERE TOO...MODERATE TO LOCALLY HEAVY RAINS
MAY GRADUALLY DEVELOP THIS MORNING OR THIS AFTERNOON.

SNOW LEVELS ARE NEAR 4K IN THE NORTH...AND 3K IN THE SOUTH WHERE
THE COLD SURFACE HIGH OVER THE GREAT BASIN CONTINUES TO PUSH COLD
AIR INTO THE DESERTS. BIG QUESTION RIGHT NOW IS IF RAIN OR SNOW
WILL DOMINATE THE DESERT REGIONS LATER THIS AFTERNOON AND TONITE.
SOME EROSION OF THE COLD AIR IS LIKELY...HOWEVER AS THE UPPER LOW
BEGINS TO PUSH INLAND LATE TONITE...EVAPORATIVE COOLING WITH THE
ONSET OF PRECIP COULD PRODUCE SOME ACCUMULATING SNOW ON THE DESERT
FLOOR. SHOULD THE COLDEST AIR FAIL TO RETREAT...SIGNIFICANT
ACCUMULATIONS OF 3-6 INCHES WILL BE POSSIBLE. WILL NEED TO WATCH
STORM PROGRESSION FOR A WHILE LONGER TO SEE WHICH OR IF WINTER WX
PRODUCTS WILL BE NEEDED ACROSS THE HIGH DESERT. IN THE SRN SIERRA
THE HEAVY SNOW WILL CONT LATE INTO THE NITE...WITH STORM TOTALS
FROM 1-3 FEET LIKELY ABOVE 4K.

AN UPSTREAM SHORTWAVE TROF IS NEAR 135W. THIS SHORTWAVE WILL BE
THE KICKING FORCE TO PUSH THE COASTAL LOW INLAND ACROSS SOCAL LATE
TONITE OR MON MORNING. THIS WILL BRING DECREASING PRECIP TO THE
REGION FROM NORTH TO SOUTH MON. AS THE MAIN UPPER LOW IS FORCED
INLAND...A SECONDARY COASTAL LOW IS FCST TO DEVELOP AND CUT OFF
NEAR 130W35N MON EVE AS AN UPPER RIDGE NOSES IN OVER THE PAC NW
AND NORCAL TUES. THIS RIDGE THEN MIGRATES INTO TO THE GREAT BASIN
BY THURS. THIS WILL BRING DRY WEATHER AND A WARMING TREND TO
CENTRAL CA BY MID WEEK...LASTING INTO FRI. MAY SEE AN INCREASE IN
VALLEY FOG BY WED MORNING...ALTHOUGH AN OFFSHORE FLOW MAY KEEP IT
MINIMIZED AS THE LOWER LEVELS DRY OUT.

FOR NEXT WEEKEND...MODELS NOT VERY CONSISTENT ON WESTERLIES
SAGGING SOUTH BACK INTO CA SAT-SUN OR NOT. FOR NOW...CONTINUED
PREV FCST OF A SHORTWAVE POSSIBLY BRINGING A SMALL CHANCE OF
PRECIP TO THE NORTH PARTS OF THE REGION...OTHERWISE CONTINUED DRY.

&&

.AVIATION...
A LOW PRESSURE SYSTEM OFF THE CENTRAL COAST WILL MOVE SLOWLY
INLAND. THIS SYSTEM WILL PROVIDE WIDESPREAD PRECIPITATION AND
MOUNTAIN OBSCURATIONS OVER THE SOUTHERN SIERRA NEVADA AND TEHACHAPI
MOUNTAINS. ISOLATED THUNDERSTORMS WILL BE POSSIBLE DURING THE
AFTERNOON TOWARDS THE NORTH PORTIONS OF THE CENTRAL VALLEY. STRONG
GUSTY WINDS ARE EXPECTED THROUGH THE TEHACHAPI MOUNTAIN PASSES
ESPECIALLY PASSES AT THE SOUTH END OF THE SAN JOAQUIN VALLEY THROUGH
00Z. ELSEWHERE MAINLY VFR WITH AREAS OF MVFR IN CLOUDS AND
PRECIPITATION THROUGH 18Z MONDAY.

&&

.AIR QUALITY ISSUES...
NONE
