AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
330 AM PST MON FEB 14 2011

.DISCUSSION...

DURING THE MORNING. EARLY MORNING COMMUTERS MAY SEE SOME RAIN BEGIN
IN THE VALLEY AS EARLY AS 6 AM. THIS INITIAL SYSTEM WILL MOVE
THROUGH THE AREA RATHER QUICKLY WITH UP TO A 1/4 INCH OF RAIN
POSSIBLE IN THE VALLEY. WITH DRIER AIR IN PLACE...SNOW LEVELS IN THE
NORTHERN SIERRA WILL START OUT AROUND 4500 FEET THIS MORNING BUT
WILL RISE TO OVER 6000 FEET THIS AFTERNOON.

THE LARGER SYSTEM WILL BEGIN TO MOVE INTO THE REGION ON TUESDAY BUT
MAY HOLD OFF ON STEADY RAIN OVER THE SOUTHERN SACRAMENTO AREA UNTIL
LATE TUESDAY NIGHT AND WEDNESDAY MORNING. STRONG SOUTHWEST FLOW WILL
DEVELOP ON MONDAY OVER THE HIGHER ELEVATIONS WITH WINDS INCREASING
OVER THE NORTH END OF THE VALLEY MONDAY NIGHT POSSIBLY TO WIND
ADVISORY LEVELS BY TUESDAY MORNING...WITH STRONGER WINDS SPREADING
SOUTH DURING TUESDAY MORNING. THERE IS GOOD INDICATION THAT UPSLOPE
FLOW MAY KEEP SHOWERS OR LIGHT RAIN FOR SOME AREAS IN THE MOUNTAIN
IN BETWEEN SYSTEMS...WITH THE HIGHER TOTALS INITIALLY OVER THE
NORTHERN MOUNTAIN BUT MOVING SOUTH OVER THE WESTERN SLOPES LATE
TUESDAY AND TUESDAY NIGHT.

COLD AIR MOVING INTO THE REGION DURING THE DAY ON WEDNESDAY WILL
LOWERING SNOW LEVELS. SNOW LEVELS LOOK TO LOWER INTO THE FOOTHILLS

.EXTENDED DISCUSSION (FRIDAY THROUGH MONDAY)...
EXTENDED MODELS FAIRLY CONSISTENT IN SHOWING DEEP TROUGH ALONG THE
WEST COAST FRIDAY. DIFFERENCES IN DETAILS WITH GFS FARTHER OFFSHORE
COULD MEAN DIFFERENCE BETWEEN PRECIP OR NO PRECIP OVER MUCH OF THE
INLAND CWA. THEREFORE...HAVE KEPT POPS IN CHANCE CATEGORY FOR NOW.
SNOW LEVELS REMAIN LOW BUT MODERATE A BIT FRIDAY AND NOT AS LOW AS
EARLIER IN THE WEEK. ALL EXTENDED MODELS THEN SHIFT MAIN TROUGH
INLAND SATURDAY FOR CHANCE POPS ALL AREAS ACROSS THE CWA. SHOULD SEE
DECREASE IN PRECIP THREAT ON SUNDAY AS MAIN UPPER TROUGH SHIFTS
INLAND AND FLOW BECOMES NORTHERLY SO WENT GENERALLY UNDER CLIMO FOR
THIS DAY. RUN TO RUN AND MODEL TO MODEL CONSISTENCY BECOME QUITE
POOR BY EARLY NEXT WEEK. LATEST GFS WANTS TO START PUSHING EASTERN
PACIFIC RIDGING INLAND WHILE ECMWF WANTS TO LEAVE LOW OVER NORCAL.
GEM SOMEWHERE IN THE MIDDLE. WITH MODEL UNCERTAINTY...NEAR CLIMO
POPS PROBABLY BEST BET.
