AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
940 PM PST SAT DEC 1 2007

.DISCUSSION...
A SYSTEM IS RAPIDLY MOVING TOWARDS NORTHERN CALIFORNIA THIS EVENING
FROM THE WEST. ALREADY SOME BANDS ALONG THE NORTH COAST ARE STARTING
TO ENHANCE AND THE SACRAMENTO TO REDDING GRADIENT HAS INCREASED TO
OVER 3 MB THIS EVENING. 850 MB WINDS INCREASE ON SUNDAY TO BETWEEN
45 AND 65 KNOTS DEPENDING ON WHICH MODEL YOU LOOK AT. CONCERN ON
SUNDAY WILL BE IF LOCALIZED WINDS FROM THAT LEVEL GET FORCED
TOWARDS THE SURFACE. WE WILL LIKELY NEED A WIND ADVISORY FOR THE
CENTRAL AND NORTHERN SACRAMENTO VALLEY AND SURROUNDING FOOTHILLS FOR
SUNDAY.

OTHER CONCERN IS WITH THE TIMING OF THE PRECIPITATION. MODELS
CONTINUE TO SHOW THE POSSIBILITY OF RAIN MOVING INTO SHASTA COUNTY
EARLY IN THE MORNING WHICH WOULD TRANSLATE TO SNOW IN THE
MOUNTAINS AT LOW LEVELS FOR THE MORNING HOURS. GFS INDICATES THAT
WARM AIR ADVECTION SHOULD LIFT THE SNOW LEVELS OVERNIGHT BUT LOCALLY
SOME OF THE COLDER VALLEYS COULD RECEIVE SNOW DURING THE MORNING
BEFORE WARMER AIR MIXES INTO THOSE COLDER SPOTS. OVER THE SIERRA
OVERNIGHT AND IN THE MORNING HOURS THERE COULD BE SOME SNOW FLURRIES
BUT NOTHING IS EXPECTED AS FAR AS ACCUMULATING SNOW AT THIS TIME.

THE RAIN SEEMS TO STAY OVER THE NORTHERN PART OF THE VALLEY AND
SURROUNDING AREAS FOR SUNDAY AND THEN LIFTS SLIGHTLY NORTHWARD A
LITTLE FOR SUNDAY NIGHT TO REDUCE THE CHANCES OF PRECIPITATION. ITS
NOT UNTIL MONDAY NIGHT AND TUESDAY BEFORE THE SACRAMENTO AREA WILL
HAVE A CHANCE OF PRECIPITATION AS THE COLD FRONT WITH THIS SYSTEM
MOVES INTO THE REGION. THE SYSTEM STILL LOOKS LIKE IT LOOSES AT LOT
OF ITS PUNCH AS IT TRIES TO CROSS THE COASTAL RANGE FOR THE SOUTHERN
HALF OF THE SACRAMENTO VALLEY.

.AVIATION...
MVFR CIGS OVER W SLOPE SIERNEV WHERE SWLY/UPSLOPE FLOW WILL CONTINUE
