A cold front moved onshore during this interval...bringing high winds to the coast and to the typically windiest inland locations. A High Wind Warning was issued for Oregon zones ORZ021/022 at 17/0345 PST, effective from 17/2200 til 18/0700 PST. It was extended until 18/1000 PST at 18/0346 PST. It was cancelled at 18/0946 PST.

EXPECTED FOR THE EAST TONIGHT AND AGAIN TUESDAY. ALSO MADE SOME
CHANGES TO THE SNOW LEVELS TO ACCOUNT FOR CURRENT OBSERVED LEVELS
AND AN EXPECTED SLIGHT RISE OVERNIGHT. THE EXCEPTION WILL BE FROM
MT. SHASTA NORTHWARD TO NEAR THE CALIFORNIA BORDER WHERE STRONG
UPSLOPE AND HEAVIER PRECIP WILL LIKELY KEEP SNOW LEVELS NEAR 3500
FEET THROUGH THE DURATION. MT. SHASTA AREA MAY MIX WITH OR CHANGE

ARE EXPECTED TO REMAIN LIGHT IN INTENSITY.
THEN...A LOW APPROACHING THE OREGON COAST THIS EVENING IS
FORECAST TO BRING ANOTHER ROUND OF STRONG WINDS TO THE COAST WITH
RAIN AND SNOW OVER THE AREA. ALONG THE COAST...THE NAM RUN
CONTINUES TO SHOW A STRONG LOW LEVEL 925 MB JET MOVING INTO THE
COAST LATE TONIGHT INTO EARLY TOMORROW MORNING. 925 MB WINDS ARE
SLIGHTLY LOWER THAN YESTERDAY BUT STILL INDICATE STRONG 70 TO 75
MPH WINDS WITH SURFACE WINDS OF 25 TO 45 MPH. HIGH WIND WARNING

ADJUSTMENTS TO THE TIMING. SNOW LEVELS WILL RISE LATE THIS EVENING
INTO TONIGHT AHEAD OF THE LOW PRESSURE SYSTEM FROM AROUND 3000
FEET TO 3500 FEET THEN LOWER TUESDAY NIGHT TO NEAR 2500 FEET ON

SYSTEMS WILL MOVE THROUGH THE CWA THURSDAY NIGHT WITH AN UPPER LEVEL
RIDGE BY FRIDAY MORNING. HOWEVER THE RIDGE WILL BE SHORT LIVED AND
WILL SHIFT EAST FRIDAY NIGHT WITH ANOTHER SYSTEM HEADED TOWARDS THE
COAST BY SATURDAY MORNING. BOTH THE GFS AND ECMWF ARE SIMILAR WITH
RESPECT TO THE PATTERN AND TIMING OF EVENTS THROUGH SATURDAY. THE
MODELS DIVERGE SOMEWHAT FROM THERE...BUT BOTH CONTINUE TO SUGGEST
THE PROGRESSIVE PATTERN WILL CONTINUE INTO AT LEAST CHRISTMAS DAY.
DETAILS REGARDING THE TIMING OF EACH SYSTEM WILL COME DOWN TO A DAY
TO DAY CALL. FOR THE MOST PART IT LOOKS LIKE IT WILL BE A GOOD
PATTERN FOR MOUNTAIN SNOW WHICH WILL HELP ADD TO THE SNOW PACK.
