AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
310 PM PST FRI DEC 12 2008

.DISCUSSION...
FIRST IN A SERIES OF SIGNIFICANTLY COLDER WEATHER SYSTEMS FROM THE
GOA AND NORTHERN CANADA IS RAPIDLY APPROACHING INTERIOR NORCAL.
INCREASED MIXING AHEAD OF THE FRONTAL SYSTEM HAS ERODED THE VALLEY
FOG. HIGH AND MID CLOUDINESS CONTINUE TO STREAM SOUTH INTO THE
FORECAST AREA THIS AFTERNOON AS SURFACE FRONT APPROACHES THE ORE-CAL
BORDER. NAM/GFS SEEM TO HAVE A DECENT HANDLE ON PRECIP TIMING AT
THIS POINT AS 88-D SHOWING SOME LIGHT PRECIP BEGINNING TO SPREAD
INTO THE FAR NORTHERN INTERIOR. FRONT PROGGED TO MOVE THROUGH
TONIGHT. PRECIP WITH FRONT CONTINUES TO BE MODELED MAINLY OVER THE
NORTHERN MOUNTAINS AND SIERRA NEVADA WITH VERY LITTLE...IF ANY...IN
THE VALLEY THROUGH SATURDAY MORNING. OVER ONE INCH PWS PLUME
ASSOCIATED WITH FRONT NARROWS AS IT MOVES SOUTH TONIGHT AND THUS
MODEL QPFS ARE LIGHT FOR THE MOUNTAINS WITH UPWARDS OF .2-.4 INCHES
OVER PORTIONS OF THE EASTERN SHASTA AND SIERRA NEVADA THROUGH
SATURDAY MORNING. THIS WOULD EQUATE TO LOW END ADVISORY CRITERIA AND
WILL HANDLE WITH A WINTER WEATHER ADVISORY. PRESSURE GRADIENTS
TIGHTEN THIS EVENING OVER INTERIOR NORCAL AS FRONTAL SYSTEM MOVES
INTO THE REGION. CURRENT GUIDANCE SUGGESTING VALLEY WINDS WILL
REMAIN BELOW WIND ADVISORY CRITERIA HOWEVER SOME LOCALIZED WIND
ADVISORY CONDITIONS ARE POSSIBLE FOR A BRIEF PERIOD JUST AHEAD AND
ALONG THE FRONTAL BOUNDARY. WRFNMM AND CANSAC ARE SHOWING AREAS OF
STRONG WIND OVER THE COASTAL MOUNTAINS TONIGHT AND WILL ISSUE A WIND
ADVISORY FOR ZONE 63. 7H WINDS PROGGED TO INCREASE TO 50-55 KTS
OVER THE SIERRA TONIGHT AND BECOME FAVORABLE FOR SOME OROGRAPHIC
ENHANCEMENT. SNOW LEVELS THIS EVENING WILL BEGIN AROUND 4500-6500
FEET BUT WILL LOWER INTO THE FOOTHILLS BY SATURDAY MORNING AS THE
MUCH COLDER AIR WORKS ITS WAY INTO INTERIOR NORCAL.

AMS CONTINUES TO COOL SATURDAY WITH 7H TEMPS LOWERING INTO THE -16
DEG C RANGE. ALTHOUGH PWS LOWER TO AROUND .3 INCHES...AMS WILL
SATURATE EASILY THOUGH AND WITH CYCLONIC FLOW WILL KEEP A THREAT OF
SHOWERS THROUGH EARLY SUNDAY...MAINLY IN THE FOOTHILLS AND
MOUNTAINS. BY SUNDAY MORNING GFS SHOWING AN AREA OF -6 DEG C AT 850
MB WHICH WOULD SUPPORT THE POSSIBILITY OF SNOW IN THE NORTHERN
SACRAMENTO VALLEY...ASSUMING THERE IS ANY PRECIP. A BETTER CHANCE
FOR SOME SNOW IN PORTIONS OF THE VALLEY IS LATER SUNDAY INTO MONDAY
WHEN A MUCH WETTER SYSTEM MOVES INTO THE REGION. THIS STORM COULD
PRODUCE A SIGNIFICANT AMOUNT OF SNOW IN THE FOOTHILLS AND MOUNTAINS
WITH SNOW RATIOS APPROACHING 15:1.

MEDIUM RANGE MODELS CONTINUE TO SIGNIFICANTLY DIVERGE ON SOLUTIONS
TOWARDS THE MIDDLE OF NEXT WEEK. THE ECMWF HOWEVER HAS BECOME MORE
LIKE THE GFS WITH THE NOTION OF DRIVING THE COLDER AIR SOUTHWARD
INTO CALIFORNIA TUESDAY. BOTH SOLUTIONS WOULD SUGGEST A BREAK IN THE
WET WEATHER LATER TUESDAY INTO WEDNESDAY FOR INTERIOR NORCAL. LONG
WAVE TROUGH HOWEVER REMAINS ALONG THE WEST COAST WITH ANOTHER SHOT
OF COLD AIR DROPPING INTO THE FORECAST AREA POSSIBLY THURSDAY OR
FRIDAY.

PCH

.AVIATION...
VFR TO MVFR HAZE PREDOMINANT OVER NORTHERN CALIFORNIA THIS
AFTERNOON. A STRONG UPPER LEVEL SYSTEM OVER THE PACIFIC NORTHWEST
WILL MOVE OVER NORTHERN CALIFORNIA TONIGHT. THIS SHOULD BRING
PRECIPITATION OVER THE SHASTA AND LASSEN COUNTY MOUNTAINS BETWEEN
02Z AND 06Z TONIGHT AND WORK SOUTHWARD ALONG THE SIERRA TOWARDS I-80
AND HWY 50 BY 09Z. SNOW LEVELS WILL RAPIDLY DROP FROM 7000 FT THIS
AFTERNOON TO 4000 FT TONIGHT TO 1500 FT SATURDAY MORNING. 10000 FT
WINDS WILL REACH 50-60 KT AHEAD OF THE FRONT AND EXTREME TURBULENCE
IS LIKELY NEAR THE SIERRA CREST TONIGHT. LIGHT SOUTHERLY WINDS IN
THE VALLEY TODAY WILL INCREASE TO 10-20 KT WITH LOCAL GUSTS TO 30 KT
AFTER 03Z.
