.UPDATE...

A PLUME OF DEEP MOISTURE CONTINUES TO STREAM IN OVER SW OR/NRN CA
THIS MORNING PRODUCING WIDESPREAD MDT/HVY PRECIP. THE FRONT IS
NEARLY STATIONARY ALONG THE COAST AND THUS PRECIP IS EXPECTED TO
CONTINUE THROUGH THE DAY TODAY. SNOW LEVELS ARE RUNNING GENERALLY
3-4KFT EXCEPT HAVE BEEN LOCALLY LOWER OVER W-CNTRL OR. I5 REMAINS
WET BUT ACCUMULATING SNOW HAS BEEN REPORTED NORTH OF ROSEBURG WITH
RICE HILL REPORTING SLUSHY/SNOW COVERED ROADWAYS. GIVEN THESE
REPORTS WILL KEEP THE WINTER WX ADVISORY ABV 1KFT UP THERE THROUGH
18Z, BUT SNOW LEVELS SHOULD BE RISING THIS MORNING AND WILL LIKELY
DROP IT ON TIME. THE REST OF THE HEADLINES REMAIN ON TRACK AND
WILL LIKELY BE CONTINUED AS IS AT THE 18Z UPDATE.

THE FRONT IS EXPECTED TO SLOWLY PUSH INTO ERN OR THROUGH THE DAY
TODAY THUS THE FOCUS OF PRECIP WILL SHIFT EAST AS WELL. MUCH
COLDER AIR AS EVIDENCED BY OPEN CELLULAR CONVECTION OVER THE OCEAN
WILL BE PUSHING IN TONIGHT. THE STEADIEST AND HEAVIEST PRECIP
WILL BE OVER BY THEN BUT ALL AREAS WILL CONTINUE TO SEE OFF AND ON
PRECIP IN THIS REGIME. WE ALSO EXPECT A BURST OF HEAVIER PRECIP
LATE TONIGHT AND EARLY TOMORROW AS A STRONG SHORTWAVE ROTATES
AROUND THE BASE OF THE TROUGH. SNOW LEVELS WILL BE GETTING
PRECARIOUSLY LOW OVERNIGHT SO WILL BE EVALUATING THE POTENTIAL FOR
LOWLAND SNOW AS WELL TODAY. -WRIGHT

.PREV DISCUSSION... /ISSUED 404 AM PST TUE FEB 15 2011/

DISCUSSION...LARGE UPPER TROUGH CONTINUES TO PIVOT SOUTHWARD FROM
THE NORTHEAST PACIFIC EARLY THIS MORNING. FRONTAL BAND ASSOCIATED
WITH THIS TROUGH IS PUSHING THROUGH THE AREA THIS MORNING AND WILL
MOVE SLOWLY EASTWARD THIS AFTERNOON REACHING THE EAST SIDE THIS
EVENING. STRONG UPWARD MOTION IS LEADING TO COOLING OF THE
ATMOSPHERIC COLUMN OVER LOWER ELEVATIONS NEAR SEXTON PASS THIS
MORNING WITH SLUSHY ACCUMULATIONS OF SNOW REPORTED ON I-5 DOWN TO
NEAR 1500 FEET. THINK THIS IS SHORT-LIVED AS PRECIPITATION
INTENSITY SHOULD LESSEN AS THE FRONT MOVES EAST IN THE NEXT COUPLE
OF HOURS AND NATURE OF PRECIP BECOMES SHOWERY.

MODERATE TO HEAVY PRECIPITATION WILL CONTINUE WITH THE FRONTAL
BAND AS IT PRESSES EASTWARD EAST OF THE CASCADES. SNOW LEVELS HAVE
RISEN TO BETWEEN 4000 AND 4500 FEET NEAR MOUNT SHASTA CITY EARLY
THIS MORNING AND WILL PROBABLY TAKE SOME TIME TO FALL BACK DOWN
TODAY. STILL THINK THERE WILL BE A GOOD PERIOD OF SNOW TONIGHT
INTO WEDNESDAY MORNING...IMPACTING I-5 AND THE CURRENT WARNING
HIGHLIGHTS THIS THREAT.

VERY STRONG WINDS WILL ALSO CONTINUE AHEAD OF THE FRONT OVER
PORTIONS OF THE SHASTA VALLEY AND THE EAST SIDE TODAY. BUT THESE
SHOULD TEND TO EASE SOMEWHAT LATER THIS AFTERNOON AND EVENING AS
CORE OF STRONG 700 MB WINDS SHIFTS INTO NORTHWESTERN NEVADA.

LATEST IR SATELLITE SHOWING PLENTY OF COLD AIR CUMULUS OVER THE
OCEAN THIS MORNING AND AS THIS COLD TROUGH MOVES IN THIS
AFTERNOON...THERE CAN BE ISOLATED THUNDERSTORMS ALONG WITH THE
SHOWERS. NOT OUT OF THE QUESTION A FEW OF THESE PRODUCE STRONG
WIND GUSTS AND EVEN SMALL HAIL. STILL COULD BE SOME THUNDER OVER
THE WATERS AND COASTAL LOCATIONS THROUGH WEDNESDAY.

SNOW LEVELS WILL DROP TO BETWEEN 1500 AND 2500 FEET WEST OF THE
CASCADES TONIGHT AND THIS MAY RESULT IN SOME ACCUMULATING SNOW
AGAIN AROUND THE PASSES OF JOSEPHINE COUNTY. CONFIDENCE IS LOW ON
SNOW AMOUNTS...BUT COULD BE ENOUGH ACCUMULATION AND IMPACT TO
WARRANT AN ADVISORY FOR TONIGHT. WILL LET THE DAY SHIFT DECIDE IF
THIS IS NECESSARY.

EXPECT BELOW NORMAL TEMPERATURES AND THE SHOWERY WEATHER PATTERN
TO CONTINUE THROUGH THE END OF THE WEEK AS THE COLD UPPER TROUGH
REMAINS ENTRENCHED OVER THE PACNW. THE GFS AND ECMWF ARE
INDICATING A BRIEF BREAK THIS WEEKEND...BUT ANOTHER STRONG TROUGH
IS EXPECTED TO DIVE SOUTHWARD FROM ALASKA SUNDAY NIGHT INTO
MONDAY.

AVIATION...GUSTY SOUTHERLY WINDS WILL CONTINUE TODAY RESULTING IN
AREAS OF WIND SPEED SHEAR...THOUGH WINDS SHOULD EASE LATER THIS
AFTERNOON IN MOST LOCATIONS. MOSTLY VFR BUT LOCAL MVFR CIGS
EXPECTED IN RAIN WITH PLENTY OF MOUNTAIN OBSCURATIONS OVER INLAND
AREAS TODAY. COULD BE LOCAL IFR ALONG THE COAST...ESPECIALLY NEAR
BROOKINGS. AREAS OF SNOW AROUND MOUNT SHASTA WILL BRING CIGS DOWN
TO IFR WITH MOUNTAIN PEAKS OBSCURED TONIGHT THROUGH WEDNESDAY
MORNING.
