AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
950 PM PST FRI NOV 19 2010

.DISCUSSION...
THE DIGGING ERN PAC TROF HAS ORIENTED THE .8 TO .9 INCH PW PLUME AND
COLD FRONT FROM SW-NE ACROSS NORCAL...AND THE MAIN FRONTAL PCPN WAS
VIRTUALLY CENTERED IN A 100 MILE WIDE BAND FROM THE SFO BAY
AREA...TO N OF REV AT 03Z. THIS SW-NE ORIENTATION PROVIDED A
FAVORABLE OROGRAPHIC TRAJECTORY FOR THE SIERNEV WHERE SNOW LEVELS
WERE GENERALLY IN THE 4-5 KFT RANGE...ALTHOUGH SEVERAL SPOTTERS
AROUND 3000 FT IN/AROUND NEVADA CITY REPORTED SNOW. THE
OROGRAPHICS ARE FORECAST TO CONTINUE THROUGH MOST OF THE NITE WHILE
THE RAIN BAND SHIFTS SWD INTO THE NRN SAN JOAQUIN VLY...SRN
MOTHERLODE AND W SLOPE SIERNEV AREAS S OF HWY 50 AFTER 06Z. BY 18Z
THIS MAIN FRONTAL BAND PCPN SHOULD BE S OF OUR AREA OR POSSIBLY
STILL AFFECTING THE FAR SRN PORTIONS OF ZONES 67/69. MEANWHILE THE
RAIN HAS STOPPED MOMENTARILY OVER THE NWRN PORTION OF THE FORECAST
AREA INCLUDING MUCH OF THE COASTAL RANGE AND SHASTA CO.

WATER VAPOR IMAGERY SHOWS THE NEXT IMPULSE OF ENERGY APPROACHING THE
NRN CA COAST WITH RADAR DETECTING SCATTERED SHOWERS JUST OFF THE
COAST. A DRY SLOT PRECEDES THIS IMPULSE AND SEPARATES THE 2 AIR
MASSES...THE MILD AND MOIST MARITIME AIR MASS THAT DID HAVE THE
SUBTROPICAL TAP EARLIER TODAY...SO LETS CALL IT MT (MARITIME
TROPICAL)...AND THE COLDER MARITIME POLAR AIR MASS THAT WILL BE
AFFECTING NORCAL THIS WEEKEND. ENTRAINED INTO THE MARITIME POLAR AIR
MASS IS ALSO CONTINENTAL POLAR AIR WHICH CAME DOWN FROM THE ARCTIC
CIRCLE AND ACROSS WRN CANADA AND INTO THE NERN PAC. THE MARITIME
POLAR AIR MASSES ARE COOL...MOIST AND UNSTABLE...AND THAT IS INDEED
WHAT WE SEE OVER THE GOA AND NERN PAC IN THE IR IMAGERY WITH
NUMEROUS CONVECTIVE CLOUDS.

ALTHOUGH THE IMPULSE AND SHOWERS OFF THE N COAST CURRENTLY SHOULD
MOVE INLAND TONITE...IT APPEARS THAT MOST OF THE SHOWERS SHOULD
DEVELOP NEAR THE COAST AND MOVE INLAND LATE SAT AFTERNOON OR BY SAT
EVENING AS THE UPPER LOW OFF THE WA COAST MOVES TO NEAR THE N COAST
BY 00Z SUN...AND THEN INLAND SAT NITE AND SUN MORNING. BASED ON THIS
TIMING...WE WILL CANCEL THE WSW FOR ZONE 64 TONIGHT...BUT THERE MAY
BE THE LIKELIHOOD OF AT LEAST AN ADVSRY FOR ZONE 64 (LAKE CO) SAT
NITE DUE TO THE COLDER AIR AND ASSOCIATED DYNAMICS AFFECTING THE
AREA. ALTHOUGH THERE MAY BE SOMEWHAT OF A LULL IN THE PCPN OVER THE
SIERNEV ON SAT...INCREASING CYCLONIC FLOW AND CONTINUED OROGRAPHICS
SHOULD KEEP AT LEAST SOME LIGHT TO MODERATE PCPN GOING THROUGH MOST
OF THE PERIOD.

ALTHOUGH MUCH LOWER PW AIR OF .3 TO .4 INCHES WILL BE COMING DOWN
WITH THE UPPER LOW...THE UNSTABLE AIR MASS WILL RESULT IN NUMEROUS
SHOWERS OVER THE AREA...POSSIBLY T-STORMS WITH SMALL HAIL AS WELL.
THE SLR (SNOW-TO-LIQUID RATIOS) SHOULD BE ABOUT 15:1 TO 20:1 SO
SIGNIFICANT SNOWFALL IS EXPECTED OVER THE SIERNEV THROUGH THE
WEEKEND.    JHM

.PREVIOUS DISCUSSION...
THE COLD FRONT HAS PROGRESSED TO A POSITION FROM NEAR UKIAH TO CHICO
TO LASSEN PARK. HILLCREST HAS PICKED UP OVER A HALF INCH OF
PRECIPITATION THIS AFTERNOON. A BAND OF MODERATE SHOWERS HAS
DEVELOPED FROM NEAR YUBA CITY TO OROVILLE. WEB CAMS FROM LASSEN PARK
SHOW ICY SNOW COVERED ROADS. CHAIN REQUIREMENTS ARE UP FOR SR-36 AND
44. RAIN AND SNOW HAS WORKED INTO THE I-80 CORRIDOR. SNOW LEVELS ARE
NEAR 6000 FEET BUT SHOULD LOWER TO 5000 FEET AS THE FRONT NEARS. A
BAND OF RAIN WILL MOVE SOUTH THROUGH THE SACRAMENTO VALLEY THIS
EVENING.

THE 125KT POLAR JET STREAM CARVES OUT A 526DM UPPER LOW OFF THE
NORCAL COAST TOMORROW AFTERNOON. THIS PUSHES INTO MT. SHASTA
SATURDAY NIGHT. INCREASING CYCLONIC FLOW AND COLD AIR ADVECTION WILL
INTERACT WITH THE OLD FRONTAL BOUNDARY TO BRING HEAVY PRECIPITATION
INTO MUCH OF OUR AREA DURING THIS TIME. A VERY STRONG UPPER
DIVERGENCE / LOWER LEVEL CONVERGENCE COUPLET STRETCHES FROM THE BAY
AREA TO LASSEN PARK AROUND MIDNIGHT. IT THEN SHIFTS SOUTH TO THE
NORTHERN SAN JOAQUIN VALLEY TO ALPINE COUNTY TOWARD SUNRISE. THE
998MB SURFACE LOW WILL SHIFT FROM SE OREGON INTO NORTHERN CALIFORNIA
AS WELL SATURDAY NIGHT.

IN THE VALLEYS...MODERATE TO HEAVY RAIN IS LIKELY AFTER 4 PM
SATURDAY. THE NAM NOW IS MORE IN LINE WITH THE GFS...SHOWING A HALF
INCH OF RAIN TONIGHT AND AN ADDITIONAL 0.75 INCHES TOMORROW
AFTERNOON THROUGH SUNDAY. THE SAME HOLDS TRUE FOR STOCKTON /
MODESTO...WHILE BOTH MODELS CONTINUE TO BACK OFF PRECIPITATION
AMOUNTS AT REDDING AND RED BLUFF. WIND GUSTS TO 35 MPH AHEAD OF THE
FRONT ARE POSSIBLE...AND FALLING LEAVES MAY AGGRAVATE NUISANCE TYPE
DRAINAGE PROBLEMS OVERNIGHT. THUNDERSTORMS MAY DEVELOP IN AN
UNSTABLE ATMOSPHERE SUNDAY AS WELL. THE GFS DEVELOPS A WAVE ALONG
THE FRONT...WHICH IS RESPONSIBLE FOR THE SLOWER MOVEMENT AND
INCREASED PRECIPITATION AMOUNTS DEPICTED BY THE GFS.

IN THE FOOTHILLS...SNOW LEVELS BETWEEN 2500 AND 3000 FEET WILL DROP
TO 1500 FEET SUNDAY MORNING. ELEVATIONS ABOVE 2000 FEET MAY RECEIVE
3 TO 6 INCHES OF SNOW...WITH UP TO A FOOT AT HIGHER ELEVATIONS. AN
INCH OR TWO OF SLUSHY SNOW MAY FALL DOWN TO 1500 FEET SUNDAY.
THUNDERSTORMS COULD ADD SMALL HAIL OR GRAUPEL TO THIS WINTRY
MIX...AND ADDITIONAL PROBLEMS MAY DEVELOP WHEN NEAR FREEZING
OVERNIGHT TEMPERATURES ARRIVE SUNDAY AND MONDAY NIGHTS. WE WILL
UPGRADE THE W.S. WATCH TO A WARNING ABOVE 2000 FEET SATURDAY EVENING
THROUGH SUNDAY AFTERNOON. NEVADA CITY...GRASS VALLEY AND MAGALIA
WILL BE IMPACTED BY SNOW. PARADISE MAY RECEIVE A SLUSHY INCH OR TWO
OF SNOW SUNDAY. AUBURN IS NOT EXPECTED TO GET ACCUMULATING SNOWFALL.

IN THE COASTAL MOUNTAINS AND BURNEY BASIN...OUR W.S. WATCH HAS BEEN
UPGRADED TO A WARNING ABOVE 2000 FEET FROM SATURDAY MORNING THROUGH
EARLY SUNDAY AFTERNOON. PERIODS OF SNOW ARE LIKELY WITH STRONG WINDS
AS THE UPPER LOW MOVES IN SATURDAY. SNOW LEVELS WILL DROP FROM 2500
FEET TO BELOW 2000 FEET SUNDAY MORNING...POSSIBLY IMPACTING THE
HIGHER ELEVATIONS OF INTERSTATE 5. THE BURNEY BASIN WILL BE SHADOWED
OUT AT FIRST...BUT HEAVY SNOW IS LIKELY THERE AFTER 6 PM SATURDAY
WITH THE UPPER LOW. STRONG WEST-SOUTHWEST WIND GUSTS TO 45 MPH WILL
PROVIDE BLIZZARD CONDITIONS AT TIMES IN THESE AREAS.

IN THE SIERRA AND LASSEN PARK...SNOW MAY DECREASE BRIEFLY LATE
TONIGHT AND EARLY SATURDAY MORNING...BEFORE REALLY PICKING UP
SATURDAY AFTERNOON. 1000-500MB THICKNESSES FALL TO 526 DM SATURDAY
AFTERNOON. THE COLD AIR ALOFT PROVIDES EXCELLENT MICROPHYSICAL SNOW
GROWTH PROCESSES. ADDITIONALLY THERE IS A 45KT 850-700MB LOW LEVEL
JET ORIENTED JUST SOUTH OF SOUTHWEST FOR A PERIOD OF EXCEPTIONAL
OROGRAPHICS SATURDAY NIGHT. 2 TO 3 INCH PER HOUR SNOWFALL RATES MAY
RESULT...WITH SNOW TO WATER RATIOS OF 20:1. THE OROGRAPHICS DROP OFF
SUNDAY MORNING...HOWEVER INSTABILITY SNOW SHOWERS WILL CONTINUE
THROUGH THE DAY SUNDAY. AND THERE IS YET ANOTHER RE-ENFORCING SHOT
OF COLD (500MB TEMPERATURES NEAR -35C) AIR ARRIVING SUNDAY NIGHT.
MORE THEN FOUR FEET OF SNOW MAY FALL ABOVE 7000 FEET BY SUNDAY
NIGHT. ROAD CLOSURES OF MAJOR PASSES IN THE SIERRA SUCH AS
INTERSTATE 80 AND HIGHWAY 50 ARE LIKELY. DO NOT TRAVEL IN THE
MOUNTAINS SATURDAY NIGHT AND SUNDAY MORNING IF AT ALL POSSIBLE. YOU
MAY NOT HAVE A CHOICE IN THE MATTER.

SHOWERY WEATHER IS LIKELY TO CONTINUE INTO SUNDAY WITH THE ARRIVAL
OF ANOTHER SHORT WAVE IN THE EVENING. SG

.EXTENDED DISCUSSION (MONDAY THROUGH FRIDAY)...
UPPER LEVEL TROUGH MOVES OFF TO THE EAST ON MONDAY BUT A WAVE DROPS
DOWN THE BACKSIDE INTO NORTHERN CALIFORNIA ON MONDAY BRINGING
ADDITIONAL SHOWERS TO THE AREA. COLD AIR MASS DOWN FROM CANADA IS
EXPECTED TO BRING 850 MB TEMPERATURES BELOW 0 AND AND 700 MB
TEMPERATURES AROUND -13 DEG C MONDAY MORNING BRINGING SNOW LEVELS
DOWN TO AROUND 1000 FEET TO 2000 FEET. THIS WOULD POSSIBLY BRING
SNOW TO THE NORTHERN PARTS OF REDDING. COLD AIR MASS WILL ALSO
LINGER OVER THE AREA WITH HIGH AND LOW TEMPERATURES RUNNING ABOUT 10
DEGREES BELOW NORMAL FOR THIS TIME OF YEAR. ANOTHER WAVE MAY DROP
DOWN THE BACK SIDE SKIRTING OVER THE EDGE OF NORTHERN CALIFORNIA
TUESDAY BRINGING ANOTHER CHANCE OF SHOWERS OVER THE MOUNTAINS.
ALTHOUGH THE MODELS HAVE VARIED WITH HOW FAR EAST THIS WAVE WILL BE
IF IT IS OVER NEVADA TUESDAY WE MAY BE DRY SO LEFT CHANCE OVER THE
SIERRA AND SLIGHT CHANCE OVER THE REST OF THE MOUNTAINS FOR NOW.
THERE MAY BE ANOTHER WAVE TUESDAY NIGHT SO LINGERED SLIGHT CHANCE OF
SHOWERS OVER THE SIERRA. AREAS OF FROST AND FOG MAY BE POSSIBLE IN
THE VALLEYS TUESDAY AND WEDNESDAY MORNINGS IF THE SKIES CLEAR
ALLOWING FOR GOOD RADIATIONAL COOLING AND IF THE WINDS REMAIN
LIGHT.  ALL THE MODELS AGREE ON A DRY THANKSGIVING DAY AND FRIDAY
WITH TEMPERATURES WARMING UP TO NEAR NORMAL. ALTHOUGH MAY HAVE SOME
FOG AND LOW CLOUDS IN THE VALLEYS...ESPECIALLY IN THE MORNINGS.
