AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
325 PM PST WED NOV 30 2005

.DISCUSSION...
VERY COMPLEX WEATHER SCENARIO UNFOLDING. NEXT PACIFIC STORM IS MOVING
ONSHORE WITH LEADING WARM FRONT PRODUCING VERY STRONG WAA PATTERN.

NORMALLY THIS WOULD BE A NON WINTER ISSUE FOR THE NORTHERN AND
COASTAL MOUNTAINS. HOWEVER...THE RECENT SNOWCOVER AND TRAPPED COLD
AIR IS THROWING A MONKEY WRENCH INTO THAT FORMULA. THIS COLD LOW
LEVEL AIR WILL COMBINE WITH STRONG UVV TO KEEP VERTICAL AIR COLUMN
MARGINALLY COLD ENOUGH FOR SNOW ACROSS PARTS OF ZONE 13...14 AND
PERHAPS NORTHERN ZONE 63 INTO LATE TONIGHT.

ELSEWHERE ACROSS THE SIERRA WE SHOULD SEE INITIALLY HIGH SNOW LEVELS
AS 700MB TEMPS REMAIN BETWEEN -1C AND -3C FOR MUCH OF THE EVENT.
THERE IS MUCH LESS TRAPPED COLD AIR ACROSS THE WEST SLOPES OF THE
SIERRA...SO SNOW LEVELS WILL LIKELY FLUCTUATE WITH INCREASING AND
DECREASING UVV. THE GOOD NEWS HERE IS THAT MOST OF THE SNOW THAT
STICKS TO THE GROUND WILL BE ABOVE 7000 FEET WHICH ENCOMPASSES VERY
LITTLE ROAD LENGTH ACROSS I-80 AND HIGHWAY 50. HIGHWAY 88 COULD SEE A
MORE SIGNIFICANT EFFECT THRU CARSON PASS AT ABOVE 8600 FT. THE BAD
NEWS IS THAT 3 TO 5 INCHES OF QPF IS POSSIBLE IN THE NEXT 36 HOURS.
THIS COULD BE AN EVENT WHERE THE PARKING LOTS OF MANY SKI AREAS GET
VERY LITTLE SNOW...WHILE THE UPPER SLOPES GET SEVERAL FEET OF PURE
SIERRA CEMENT.

AS WITH ANY STRONG PACIFIC STORM...WINDS WILL ALSO BE AN ISSUE. HAVE
GONE WITH A WIND ADVISORY FOR THURSDAY ACROSS THE NORTHERN 2/3RDS OF
THE INTERIOR VALLEY AS 850 MB SOUTHWEST WINDS ARE PROGGED AT 40-50
KTS BY THE NAM BY THURSDAY MORNING. GUSTS COULD EXCEED 60 MPH ACROSS
THE HIGH SIERRA.

COLD FRONT WILL MOVE THRU THE REGION LATE THURSDAY. THE NAM AND GFS
SHOW 700 MB TEMPS FALLING FROM -2C TO -12C FROM THURSDAY AFTERNOON TO
THURSDAY NIGHT. FORTUNATELY MOST OF THE PRECIP WILL BE DONE BY
THEN...BUT THIS COLDER AIR WILL STEEPEN THE LAPSE RATES ENOUGH THAT
OROGRAPHIC ENHANCEMENT COULD GET GOING ACROSS THE SIERRA LATE
THURSDAY NIGHT.

THIS SYSTEM BEGINS TO TAPER DOWN BY EARLY FRIDAY. LEFT SOME LIGHT
POPS IN FOR A PORTION OF SATURDAY ACROSS THE MOUNTAINS.
