AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
917 AM PST WED NOV 28 2012

.SHORT TERM DISCUSSION...

THE FIRST OF A SERIES OF STORMS...A NEGATIVELY TILTED WAVE IS
MOVING THROUGH THE AREA TODAY. ADDITIONAL WAVES ARE EXPECTED TO
MOVE THROUGH THURSDAY NIGHT INTO FRIDAY AND SATURDAY NIGHT INTO
SUNDAY. THESE SYSTEMS WILL BRING PERIODS OF MODERATE TO HEAVY
PRECIPITATION AND BREEZY AND GUSTY SOUTHERLY WINDS AT TIMES.
PRECIPITATION HAS BEGUN THIS MORNING ALONG WITH A COUPLE ISOLATED
THUNDERSTORMS NEAR SACRAMENTO AND STOCKTON. PRECIPITABLE WATER
VALUES OVER THE AREA ARE ALMOST AN INCH WHICH IS OVER 200 PERCENT
OF NORMAL FOR THIS TIME OF YEAR. PRECIPITATION AMOUNTS TODAY ARE
EXPECTED TO BE AROUND HALF AN INCH TO AN INCH IN THE SACRAMENTO
VALLEY WITH THE HIGHEST AMOUNTS IN THE NORTH AND AROUND A HALF AN
INCH IN THE NORTHERN SAN JOAQUIN VALLEY AND AROUND ONE TO TWO
INCHES IN THE HIGHER ELEVATIONS. SNOW LEVELS WILL BE AROUND 5000
TO 6000 FT. THE MAIN IMPACTS WITH THIS FIRST SYSTEM WILL BE
RELATED TO BRIEF LOCALLY HEAVY DOWNPOURS WHICH MAY RESULT IN
NUISANCE TYPE FLOODING AS STORM DRAINS BECOME CLOGGED WITH
LEAVES...AND SOME ACCUMULATING SNOW IN LASSEN NATIONAL PARK AND
NEAR THE PASS LEVELS IN THE NORTHERN SIERRA (WINTER WEATHER
ADVISORY CONTINUES ABOVE 6000 FT). SOUTHERLY WINDS WILL INCREASE
AND BECOME GUSTY THIS MORNING AND EARLY AFTERNOON AHEAD OF THE
FRONT...WITH THE STRONGEST WINDS MAINLY AROUND INTERSTATE 80
CORRIDOR AND SOUTH (WIND ADVISORY CONTINUES). PRECIPITATION WILL
TAPER OFF BY THIS EVENING BEHIND THE FRONT AND SOME AREAS MAY EVEN
SEE A BREAK IN THE PRECIPITATION TONIGHT INTO EARLY
THURSDAY...ESPECIALLY IN THE VALLEY. ANOTHER WAVE MOVES IN LATE
THURSDAY INTO FRIDAY AND THE NEXT ONE LATE SATURDAY INTO SUNDAY SO
PROBABLY WILL NOT SEE MUCH OF A BREAK FRIDAY INTO THE WEEKEND.
THESE WAVES WILL BRING SIGNIFICANT PRECIPITATION WHICH WILL
INCREASE FLOODING CONCERNS THURSDAY INTO THE WEEK (FLOOD WATCH IN EFFECT).
PERIODS OF STRONG AND GUSTY WINDS ARE ALSO EXPECTED WITH THESE
STORMS. SNOW LEVELS WILL VARY BUT ARE EXPECTED TO RISE TO AROUND
6000 TO 7000 FT BY FRIDAY AND 7000 TO 8000 FT SATURDAY NIGHT AND
THE FALL TO 5000 TO 6000 FT ON SUNDAY. PRECIPITABLE WATER VALUES
INCREASE TO AROUND AN INCH AND A HALF BY SATURDAY NIGHT.
THE PROLONGED DEEP MOISTURE TAP ALONG WITH STRONG OROGRAPHIC
ENHANCEMENT WILL LIKELY RESULT IN SOME VERY IMPRESSIVE PRECIP
TOTALS BY THE END OF THE WEEKEND. FOR SEVERAL DAYS MODELS HAVE
BEEN CONSISTENT IN POINTING TOWARD VERY HEAVY QPF ACROSS MUCH OF
THE INTERIOR OF NORCAL LENDING CONFIDENCE TO THE FORECAST. IT/S
STILL LOOKING LIKE THE HEAVIEST QPF TOTALS THROUGH SUNDAY WILL BE
FOCUSED OVER SHASTA COUNTY (A LARGE AREA OF 12-18 INCHES OR MORE
POSSIBLE) AND EASTERN BUTTE/WESTERN PLUMAS COUNTIES (LARGE AREA OF
15-20 INCHES OR MORE POSSIBLE). VALLEY TOTALS ARE EXPECTED TO BE
ABOUT 4 TO 8 INCHES IN THE SACRAMENTO VALLEY WITH LOCALLY HIGHER
AMOUNTS POSSIBLE ESPECIALLY AROUND REDDING AND 2 TO 4 IN THE
NORTHERN SAN JOAQUIN VALLEY. THE GFS HAS BEEN CONSISTENTLY
INDICATING AN AREA OF HEAVY QPF IN THE VALLEY CENTERED ALONG I-80
WITH 6-8 INCHES THROUGH SUNDAY (LIKELY ASSOCIATED WITH AN AREA OF
ENHANCED CONVERGENCE). SEVERAL FEET OF SNOW ARE POSSIBLE ABOVE
7000 FT THROUGH THE WEEKEND.

WIDESPREAD SIGNIFICANT IMPACTS ARE LIKELY ACROSS THE REGION
ASSOCIATED WITH THIS SERIES OF STORMS FROM HEAVY PRECIP AND STRONG
WINDS. BE PREPARED AND STAY TUNED FOR THE LASTEST
FORECASTS!

.EXTENDED DISCUSSION (SUNDAY THROUGH WEDNESDAY)

LAST IN SERIES OF MAJOR WAVES TO PIVOT OUT OF GULF OF ALASKA LOW
WILL MOVE ONTO THE WEST COAST SUNDAY MORNING. THIS LOOKS TO BE
ANOTHER POWERFUL STORM WITH HEAVY PRECIPITATION AND STRONG WINDS.
SURFACE GRADIENTS FROM SACRAMENTO TO MEDFORD FORECAST TO TOP 10 MB
WITH GFS 850 MB WINDS SHOWING WINDSPEEDS OVER 50 KNOTS. LARGE QPFS
ARE INDICATED AS WELL WITH THIS FRONTAL SYSTEM. CURRENT TIMING
PUTS THE MAIN FRONT INTO THE SIERRA BY AFTERNOON. SNOW LEVELS WILL
START OUT FAIRLY HIGH IN WAA AHEAD OF THE FRONT THEN DROP IN THE
AFTERNOON AS COLD AIR FILTERS IN BEHIND THE FRONT. WILL LIKELY
PICK UP SOME SNOW AT THE PASS LEVELS IN THE AFTERNOON BUT BY
THEN...PRECIP SHOULD BE WINDING DOWN AS WELL AS THE WINDS AS
GRADIENTS RELAX. EXTENDED MODELS ARE CONSISTENT IN BUILDING A
RIDGE OVER THE WEST COAST ON MONDAY. GFS SHOWS DRY CONDITIONS OVER
THE CWA MONDAY WITH ECMWF AND GEM MODELS SHOWING A DIRTIER RIDGE WITH
SOME PRECIP POSSIBILITIES ACROSS THE NORTHERN ZONES. THE UPPER
RIDGE BEGINS TO SHIFT EASTWARD ON TUESDAY WITH ALL MODELS STARTING
TO SLIP A THREAT OF PRECIP OVER THE NORTHWEST CORNER OF THE STATE.
MODELS REMAIN IN SURPRISINGLY GOOD AGREEMENT GOING INTO THE MIDDLE
OF NEXT WEEK WITH WHAT APPEARS TO BE ANOTHER PACIFIC FRONTAL
SYSTEM MOVING ONTO THE NORTH COAST NEXT WEDNESDAY.
