AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
355 AM PDT SAT JUN 4 2011

.SYNOPSIS...
AN UNSEASONABLY STRONG PACIFIC STORM WILL SLOWLY APPROACH THE
CENTRAL CALIFORNIA COAST TODAY AND SPREAD SHOWERY WEATHER ACROSS THE
WESTERN SAN JOAQUIN VALLEY THROUGH THE AFTERNOON. THE STORM WILL
BEGIN TO MOVE EAST LATE TONIGHT OR SUNDAY AND WILL SPREAD ADDITIONAL
RAIN AND SNOW SHOWERS ACROSS THE REGION. SNOW LEVELS WILL BE QUITE
HIGH INITIALLY BUT MAY LOWER TO 6500 TO 7000 FEET BY LATE SUNDAY. IN
ADDITION...AS THE LOW PRESSURE SYSTEM MOVES EAST THE THREAT FOR
THUNDERSTORMS WILL DEVELOP OVER MUCH OF THE VALLEY AND ADJACENT
SIERRA FOOTHILLS SUNDAY AFTERNOON AND EVENING. TEMPERATURES WILL
REMAIN MUCH BELOW NORMAL THROUGH EARLY NEXT WEEK.

&&

.DISCUSSION...
SWATH OF ANOMALOUS MOISTURE FETCH CONTINUES TO IMPINGE ON THE
CENTRAL CA COAST (SAT EST PWATS AROUND 1.5 INCH WHICH IS GREATER
THAN 200% OF NORMAL) AT THIS TIME. SOUTHWESTERLY FLOW WILL
CONTINUE TO RIDE OVER THE COASTAL MOUNTAINS THIS MORNING AND CAUSE
SHOWERS TO BREAK OUT ACROSS THE WESTERN PORTION OF THE SJV AND
INTO THE MADERA/MERCED/MARIPOSA FOOTHILLS AND NORTH OF FRESNO BY
LATE AFTERNOON.

THERE IS GOOD AGREEMENT IN ALL MODEL FIELDS THAT THE UPPER LOW
WILL CONTINUE TO SLOWLY DROP SOUTH ALONG THE COAST BUT WILL NOT
MAKE MUCH PROGRESS FURTHER EAST UNTIL POSSIBLY SUNDAY PM...KEEPING
PRECIP MAINLY SCATTERED IN NATURE TIL THEN. HOWEVER SAT NGT A
FRONTAL BOUNDARY IS EXPECTED TO SLOWLY MOVE EAST ACROSS CENTRAL
CALIFORNIA AND FORCE SOME RENEWED SHOWERY PRECIP ACROSS MUCH OF
THE SJV AND INTO THE FOOTHILLS AGAIN. HOWEVER...OROGRAPHIC LIFT IS
NOT EXPECTED TO BE FAVORABLE ACROSS THE SOUTHERN SIERRA UNTIL
LATER ON SUNDAY AND SUNDAY NGT AS THE UPPER LOW BEGINS TO MOVE OFF
EAST.

SUNDAY AFTERNOON AND EVENING AS THE COOLER AIRMASS ASSOCIATED WITH
THE UPPER LOW IS DRAWN EAST...CONVECTION IS STILL A POSSIBILITY AS
LAPSE RATES SHARPEN UP ESPECIALLY RIGHT ALONG THE PERIPHERY OF
THE LOW TRACK. TIMING WILL BE AN ISSUE AS THE LATEST MODEL PROGS
SUGGEST THE LOW MAY NOT TRACK ACROSS TIL EVENING. AT ANY RATE
THERE STILL MAY BE A THREAT OF THUNDERSTORMS ACROSS THE VALLEY AND
ADJACENT FOOTHILLS SO WILL CONTINUE TO MENTION THAT THREAT.
WRAPAROUND MOISTURE ON MONDAY MAY BRING A RENEWED THREAT FOR TSTMS
DEPENDING ON HOW MUCH COOL AIR IS AVAILABLE.

THE COOLER AIR WILL ALSO FINALLY BRING LOWER SNOW LEVELS FROM AS
HIGH AS 9000-10000 FT TODAY DOWN TO AROUND 6500-7000 FEET BY LATE
SUNDAY NIGHT. THE BEST LIFT PROBABLY WILL BE AFTER MIDNIGHT SUNDAY
NIGHT AND INTO MONDAY MORNING ACROSS THE SOUTHERN SIERRA WHEN
POSSIBLY 4 INCHES OR MORE OF SNOW COULD FALL ABOVE 7000 FEET. THIS
WOULD MEET OUR OFF-SEASON WINTER STORM CRITERIA SO LATER SHIFTS
WILL NEED TO CONSIDER ISSUING WINTER HEADLINES FOR THE SOUTHERN
SIERRA REGION WHERE SUMMERTIME ACTIVITIES ARE BEGINNING TO TAKE
SHAPE. FOR NOW WE WILL UPDATE OUR OUTLOOK PRODUCT.

THE GRADIENTS DON'T REALLY PICK UP TIL LATE SUNDAY INTO MONDAY
MORNING WHEN GUSTY WINDS COULD DEVELOP ACROSS KERN COUNTY AS WELL
AS THROUGH THE RIDGETOPS.

BELOW NORMAL TEMPS ARE EXPECTED TO CONTINUE INTO EARLY TO MID NEXT
WEEK AS A TROUGHY PATTERN PERSISTS ACROSS THE SW. THE ECMWF IS
ACTUALLY SHOWING AN INSIDE SLIDER LOW DROPPING SOUTH AND EAST OF
THE SIERRA BUT EVEN IF THAT SCENARIO PANS OUT THE BEST MOISTURE
WOULD BE WELL NORTHEAST OF THE REGION.

&&

.AVIATION...
VFR ACROSS THE CENTRAL CA INTERIOR THROUGH 18Z TODAY. THEN IN THE
SOUTHERN SIERRA FROM KINGS CANYON NORTH...AREAS OF MVFR/IFR AND
LOCAL MOUNTAIN OBSCURATIONS DEVELOPING IN CLOUDS/PRECIP...AND
CONTINUING THRU 12Z SUNDAY. IN THE SAN JOAQUIN VALLEY AND ADJACENT
FOOTHILLS...AREAS OF MVFR DEVELOPING IN SCATTERED TO NUMEROUS
SHOWERS FROM FRESNO COUNTY NORTH. ELSEWHERE VFR ACROSS THE SOUTH END
OF THE SAN JOAQUIN VALLEY...THE SOUTHERN SIERRA SOUTH OF SEQUOIA
PARK...THE TEHACHAPI MOUNTAINS AND KERN COUNTY DESERTS THRU 12Z
SUNDAY.
