AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
930 PM PST MON FEB 28 2011

.DISCUSSION...
A WEAK SW-NE ORIENTED FRONT FROM THE PAC INTO THE PAC NW PRECEDES
THE STRONGER WX SYSTEM OVER THE PAC VCNTY OF 140W. THE AIR MASS S OF
THE FRONT AND OVER INTERIOR NORCAL IS DRY AND STABLE...WITH THE
UPPER FLOW PARALLELING THE FRONT TONIGHT. IT DOES NOT LOOK LIKE THE
FRONT WILL MAKE ANY SWD PROGRESS TONIGHT...NOR WILL THE AIR MASS
MOISTEN APPRECIABLY OVER MOST OF NORCAL...AND HAVE BACKED OFF ON THE
EXTENT OF CLOUD COVER AND POPS IN THE UPDATED ZFP. MOST OF THE CLOUD
COVER IS EXPECTED TO STAY OVER THE SHASTA COUNTY AREA...WHERE
OCCASIONAL LIGHT PCPN IS EXPECTED...AND OVER THE COASTAL RANGE.
SCATTERED TO BROKEN STRATOCUMULUS IS EXPECTED TO FORM OVER THE WRN
PLUMAS CO AREA DUE TO UPSLOPE FLOW. OTHER THAN THAT...CLEAR TO
PARTLY CLOUDY CONDITIONS ARE EXPECTED.

WE SHOULD SEE ONE MORE SUNNY/DRY DAY OVER MOST OF NORCAL ON TUE AS
THERE WILL BE SOME RIDGING AHEAD OF THE APPROACHING WX SYSTEM FROM
THE PAC. THE CHANCE OF RAIN IS FORECAST TO MOVE N OF OUR CWA BY THE
AFTERNOON.

RAIN AND MOUNTAIN SNOW IS FORECAST BY THE WRF TO SPREAD W TO E TUE
EVENING. BY MIDNIGHT...THE LEADING EDGE OF THE MAIN FRONTAL BAND
PRECIP IS FORECAST TO BE ALONG I-5...WITH ISENTROPIC PROCESSES
RESULTING IN SOME LIGHT PRECIP OVER THE SIERNEV AHEAD OF THE MAIN
AREA OF PRECIP. A STRONG SLY PRESSURE GRADIENT OF 10-11 MBS IS
FORECAST FROM SAC-MFR BY 12Z WED WITH 50-55 KT 925 MBS WINDS OFF THE
NAM. THIS MAY RESULT IN SUSTAINED WINDS AND/OR GUSTS EXCEEDING
ADVISORY LEVELS IN THE VALLEY.

THIS WILL BE A WARMER STORM THAN PREVIOUS ONES AS 850 MBS TEMPS ARE
FORECAST TO STAY JUST ABOVE FREEZING OVER NORCAL. SNOW LEVELS SHOULD
STAY ABOVE THE SIERNEV FOOTHILLS THIS TIME AROUND. BEHIND THIS WX
SYSTEM...AN UPPER LEVEL TROF WILL PASS THROUGH THE AREA ON THU WITH
MORE PRECIP. QPFS WILL BE LIGHTER...ESPECIALLY IN THE VALLEY...WITH
THE HEAVIER AMOUNTS AGAIN OVER THE SIERNEV GIVEN THE W TO E MOVEMENT
OF THE TROF.      JHM

.PREVIOUS DISCUSSION...
UNSETTLED WEATHER OVER NORTHERN CALIFORNIA TODAY STAYED PRIMARILY
NORTH AND WEST OF THE CWA. LOW CLOUDS WILL CONTINUE TO FLOW OVER THE
NORTHERN MOUNTAINS TONIGHT AND LIGHT PRECIPITATION IS POSSIBLE WITH
SOME SNOW ACCUMULATION AT THE HIGHER ELEVATIONS.

THE THE ALASKAN LOW IS SITUATED IN THE EASTERN GULF AND LOOKS TO
MOVE LITTLE DURING THE NEXT FEW DAYS.  FROM ITS POSITION... MULTIPLE
SHORT WAVES GET PULLED IN AND SPUN INTO THE PACIFIC NORTHWEST
INCLUDING THE WEATHER GOING ACROSS THE NORTHERN MOUNTAINS TODAY.  A
BRIEF PERIOD OF RIDGING WILL OPEN UP THE CLOUDS EARLY ON TUESDAY
ACROSS NORCAL AND ALLOW SOME ADDITIONAL WARMING IN THE AREA.  A MORE
SIGNIFICANT SHORT WAVE APPROACHES THE REGION ON TUESDAY AND MAY TAP
INTO A WEAK PW BAND OFF THE COAST.  THE RESULT WILL BE PRECIPITATION
DOWN ACROSS THE SIERRA NEVADA RANGE WITH LESS IMPACT IN THE NORTHERN
MOUNTAINS.

SNOW LEVELS WITH THIS NEXT STORM WILL BE MORE TYPICAL OF A SIERRA
NEVADA WINTER STORM.  MOST SNOW WILL FALL AT AND ABOVE 5000 FEET
WITH HIGHEST SNOW AMOUNTS FALLING ABOVE 7000 FEET.  SOME SNOW WILL
FALL AS LOW AS 3500 FEET IN THE FAR NORTH AND DOWN TO 4500 FEET IN
THE SOUTH.  WINDS WILL BE 15 TO 25 MPH IN MOST AREAS WITH GUSTS TO
50 MPH THROUGH THE HIGHER PASSES.  WINDS IN THE CENTRAL VALLEY WILL
INCREASE AHEAD OF THE STORM BUT CURRENTLY LOOK TO STAY BELOW
ADVISORY LEVELS.

THE STRONGEST PART OF THE STORM WILL COME EARLY WEDNESDAY INTO
MIDDAY WEDNESDAY BUT WILL CONTINUE THROUGH LATE WEDNESDAY NIGHT.
SOME PORTIONS OF THE SIERRA NEVADA SOUTH OF LAKE TAHOE WILL KEEP
LIGHT SNOW UNTIL EARLY THURSDAY MORNING.  CLEARING SKIES AND WARMING
TEMPERATURES WILL PREVAIL ACROSS THE REGION ON THURSDAY.

.EXTENDED DISCUSSION (THURSDAY NIGHT THROUGH MONDAY)
EXTENDED MODELS SHOW SHORTWAVE RIDGING BUILDING IN OVER THE AREA
BEGINNING THURSDAY NIGHT SO SHOULD SEE SHIFT IN PRECIP THREAT TO THE
NORTH GOING INTO FRIDAY. OTHER THAN A SLIGHT THREAT OF SHOWERS OVER
THE NORTHERN MOUNTAINS...MOST LOCATIONS SHOULD SEE A DRY DAY ON
FRIDAY WITH NEAR TO A LITTLE BELOW NORMAL DAYTIME TEMPERATURES. WEST
COAST RIDGING WILL BE SHORT LIVED WITH EXTENDED MODELS SHOWING NEXT
PACIFIC STORM SYSTEM PUSHING INLAND FRIDAY NIGHT OR SATURDAY. LATEST
GFS ABOUT 12 HOURS FASTER WITH THIS PROCESS THAN ECMWF. GEM
CURRENTLY MORE IN LINE WITH ECMWF SO MAY HAVE TO BACK OFF ON TIMING
A BIT FOR ONSET OF NEXT ROUND OF PRECIP. EITHER WAY...SECOND HALF OF
WEEKEND LOOKS WET AS FRONTAL SYSTEM PUSHES THROUGH. ORIGINS OF THIS
SYSTEM FROM THE CENTRAL PACIFIC SHOULD MAKE FOR MODERATE SNOW
LEVELS.  FOR EARLY NEXT WEEK...COLD UPPER LOW DROPPING OUT OF GULF
OF ALASKA WILL MAINTAIN AN UNSETTLED WEATHER PATTERN WITH SNOW
LEVELS POSSIBLY DROPPING BACK DOWN INTO THE FOOTHILLS.
