.DISCUSSION...

.UPDATE...
AUTOMATED SENSORS SHOW PORTIONS OF SHASTA COUNTY AND TRINITY COUNTY
RECEIVED 8 TO 16 INCHES OF SNOW ABOVE 5000 FEET...AND TUOLUMNE
COUNTY SENSORS NEAR 8000 FEET PICKED UP 16 INCHES OF SNOW TODAY WITH
PLENTY OF 12-18 INCH TOTALS...BELIEVE THE SKI REPORTS WILL COME IN
TOMORROW MORNING WITH SOME 2 TO 3 FOOT TOTALS.  LOWER LASSEN PEAK
PICKED UP 3.5 INCHES OF WATER EQUIVALENT TODAY...COULD TRANSLATE TO
OVER 4 FEET OF SNOW.

FLAT RIDGE BUILDS IN BRIEFLY TONIGHT...BUT NEXT SYSTEM NEAR 45/132
MOVING EAST RAPIDLY THANKS TO A 160KT JET CORE. STRATUS CLOUDS HAVE
FORMED AND BUMPED UP AGAINST THE EAST AND NORTH SIDES OF THE
SACRAMENTO VALLEY. THESE MAY PERSIST INTO MORNING.
ADDITIONALLY...WHERE THERE IS CLEARING EXPECT AREAS OF DENSE FOG MAY
DEVELOP. UPDATED THE ZONES TO REFLECT THESE TRENDS. DENSE FOG ALSO
OCCURRING OVER THE SIERRA AS ONLY ISOLATED SNOW SHOWERS REMAIN OVER
TUOLUMNE AND ALPINE COUNTY.

APPROACHING SYSTEM CONTAINS MORE COLD AIR...APPEARS MORE
CONSOLIDATED (THE LAST ONE SPLIT AS IT CAME IN) WITH THE JET
REMAINING FURTHER NORTH. THUS HIGHER PRECIPITATION TOTALS WILL BE IN
THE NORTHERN SAC VALLEY REDDING/RED BLUFF AREAS...PERHAPS AN
INCH...TAPERING TO A QUARTER INCH AT STOCKTON OR MODESTO. MOS
GUIDANCE ALSO BRINGING IN WIND ADVISORY TYPE WINDS TO THE REDDING /
RED BLUFF AREAS AGAIN TOMORROW EVENING. THIS SYSTEM APPEARS TO BE A
1-2 FOOT SNOWSTORM FOR THE MOUNTAINS AGAIN. THE BURNEY BASIN WILL
LIKELY HAVE MORE SNOW AND LESS SHADOWING. 700MB TEMPS DROP TO -12C
TO -15C BY EARLY THURSDAY MORNING...BUT THE BULK OF THE
PRECIPITATION SHOULD HAVE FALLEN BY THEN. LOOK FOR SNOW LEVELS IN
THE SIERRA 4000 TO 4500 FEET BY WEDNESDAY AFTERNOON. THEY FALL TO
2000 FEET IN SHASTA COUNTY BY THURSDAY MORNING AS WELL.

A DRYING PERIOD THEN APPEARS TO DEVELOP FRIDAY INTO THE WEEKEND AS A
RIDGE AMPLIFIES ALONG THE WEST COAST. BREEZY NORTH WINDS MAY
MITIGATE FOG CONCERNS AT FIRST...BUT FOG WILL BE MORE LIKELY OVER
THE WEEKEND. A WEAKER WEATHER SYSTEM MAY AFFECT THE REGION X-MAS
EVE...IT DOES NOT LOOK AS IF IT WILL CREATE ANY MAJOR TRAVEL
PROBLEMS AT THIS TIME.

WINTER BEGINS AT 10:08 PM FRIDAY DECEMBER 21ST.

.AVIATION...
LINGERING SHOWERS WILL CONTINUE OVR MTNS OVERNIGHT. MTNS WILL REMAIN

MAY SCATTERED OUT TONIGHT AND CONDITIONS BECOMING VFR OVER THE SRN
SAC AND NRN SJ VLYS TOWARD MORNING. THIS COULD LEAD TO FOG ISSUES.
THE NEXT SYSTEM WILL BEGIN TO SPREAD CLOUDS AND LIGHT PRECIPITATION
INTO THE NORTHERN PART OF THE VLY AFT 10Z...WITH CLOUDS SPREADING
OVER THE SOUTHERN PART OF THE VLY AFT 14Z. WINDS AND PRECIPITATION
WILL INCREASE OVR THE MTNS ON WEDNESDAY AHEAD OF THE FRONT WITH A
