AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
953 PM PST WED DEC 19 2007

.UPDATE...UPDATED ZONES AND WINTER STORM/SPECIAL WEATHER
STATEMENTS TO LOWER QPF/SNOWFALL AMOUNTS.

&&

.DISCUSSION...PRECIPITATION FINALLY BEGINNING TO MOVE INTO THE
NORTHERN PORTION OF THE CWFA THIS EVENING. EXPECT PRECIP TO
CONTINUE TO MOVE SOUTH OVERNIGHT AND THROUGH THE DAY THURSDAY.
HEAVIEST AMOUNTS OF PRECIP ARE EXPECTED TO OCCUR OVER THE NORTHERN
HALF OF THE DISTRICT. THE 00Z MODEL RUN IS INDICATING LESS QPF
THAN WAS INDICATED IN THE CURRENT FORECAST OVER THE SIERRA. HAVE
UPDATED QPF AND SNOWFALL AMOUNTS TO TREND A LITTLE MORE TOWARD THE
00Z RUN. ONE TO TWO FEET OF SNOW IS POSSIBLE OVER THE HIGHER
ELEVATIONS NEAR YOSEMITE. PRECIP AMOUNTS DECREASE RAPIDLY AS YOU
MOVE SOUTHWARD. SNOWFALL AMOUNTS IN THE TULARE COUNTY MOUNTAINS
WILL BE MARGINAL FOR A SNOW ADVISORY...BUT WILL LET THE NEXT
SHIFT EVALUATE AS PRECIP MOVES FARTHER SOUTH.

THE PRECIPITATION IS EXPECTED TO END THURSDAY EVENING AS THE
TROUGH AXIS SWINGS THROUGH CENTRAL CA. PROJECTED SNOW LEVELS STILL
LOOK REASONABLE...AROUND 6500 FEET AS PRECIPITATION BEGINS THIS
EVENING LOWERING TO 5000 FEET ON THURSDAY THEN DOWN TO 3000 FEET
BY THE TIME THE PRECIPITATION ENDS THURSDAY EVENING OVER THE
SOUTHERN SIERRA NEVADA. THIS SYSTEM WILL ALSO PRODUCE BREEZY
CONDITIONS OVER THE KERN MOUNTAINS AND DESERTS THURSDAY AFTERNOON
AND EVENING AS THE COLD FRONT PUSHES THROUGH.

FROM PREVIOUS DISCUSSION...THE NEXT FORECAST CONCERN TO DEAL WITH A
FOLLOWING THIS STORM AS HIGH PRESSURE AMPLIFIES AND BUILDS INLAND
ON FRIDAY...BRINGING A COOLER AND DRIER AIRMASS INTO CENTRAL CA.
RESIDUAL LOW LEVEL MOISTURE IN THE CENTRAL AND SOUTH VALLEY WILL
ALLOW FOR FOG TO FORM IF LOW LEVEL WINDS DIMINISH.
HOWEVER...TEMPERATURES IN FOG FREE AREAS WILL DROP BELOW THE
FREEZING MARK AND FROST MIGHT BECOME A CONCERN. ESPECIALLY ON
FRIDAY NIGHT AS THERE RIDGE STRENGTHENS. SHORTWAVE ENERGY MOVING
INTO THE PAC NW SATURDAY NIGHT AND SUNDAY WILL ALLOW FOR ENOUGH
MIXING FOR FROST AND FOG TO BE LESS OF A CONCERN ON SATURDAY
NIGHT...ESPECIALLY IF SOME OVERRUNNING MID LEVEL MOISTURE PUSHES
INTO CENTRAL CA. THERE IS STILL SOME MODEL UNCERTAINTY FOR NEXT
WEEK...BUT THE MEDIUM RANGE MODELS HAVE COME INTO BETTER AGREEMENT
WITH A TROUGH MOVING INLAND OVER THE PAC NW ON MONDAY AND KEEP THE
DEEPER MOISTURE AND DYNAMIC NORTH OF OUR CWFA. WILL MENTION A
SLIGHT CHANCE OF RAIN AND HIGHER ELEVATION SNOW OVER THE SOUTHERN
SIERRA NEVADA MOUNTAINS FOR MONDAY AND CHRISTMAS EVE. SHORTWAVE
RIDGING THEN MOVES INTO CENTRAL CA FOR CHRISTMAS DAY BEFORE A
POTENTIALLY STRONGER SYSTEM MOVES THROUGH THE PAC NW AND NORCAL ON
WEDNESDAY. WILL MENTION SLIGHT CHANCE TO LOW CHANCE POPS WITH THIS
SYSTEM FOR NOW SINCE THERE IS A LIT OF UNCERTAINTY SEVEN DAYS OUT.
WILL TREND TEMPS TOWARD CLIMO LATER IN THE PERIOD.

&&

.AVIATION...ACROSS THE SAN JOAQUIN VALLEY... RAIN AND
HIGHER-ELEVATION SNOW WILL SPREAD INTO THE CENTRAL CALIFORNIA
INTERIOR TONIGHT...RESULTING IN WIDESPREAD MVFR CEILINGS
AND VISIBILITIES THROUGH 06Z FRIDAY. VFR CONDITIONS WILL PREVAIL
ACROSS THE KERN DESERTS THROUGH 06Z FRIDAY.

&&

.AIR QUALITY ISSUES...
NONE

.HNX WATCHES/WARNINGS/ADVISORIES...
WINTER STORM WARNING UNTIL 6 PM PST THURSDAY FOR CAZ096.
