AN ARCTIC FRONT MOVING THROUGH THE GORGE INTO THE REGION WEST OF

WELL...MAINLY MONDAY MORNING. AMOUNTS MIGHT REACH AROUND 1 INCH
AND COULD CAUSE SOME TRAVEL PROBLEMS.

THE COLDEST WEATHER OF THE WINTER SEASON SO FAR WILL IMPACT
SOUTHWEST WASHINGTON AND NORTHWEST OREGON LATE MONDAY THROUGH
WEDNESDAY AS THIS ARCTIC FRONT MOVES THROUGH. BRISK COLD EAST
WINDS WILL BEGIN TO DEVELOP ACROSS THE AREA MONDAY AFTERNOON...AND
INCREASE IN EARNEST OVER THE AREA MONDAY NIGHT.

EAST WINDS WILL LIKELY GUST TO 60 TO 70 MPH IN THE WINDIEST AREAS
OF THE COLUMBIA RIVER GORGE MONDAY NIGHT AND TUESDAY. EAST WINDS
COULD ALSO GUSTS AS HIGH AS 50 TO 60 MPH IN THE PORTLAND AND
VANCOUVER METRO AREAS AND THE ADJACENT CASCADE FOOTHILLS...AND
COULD BE LOCALLY STRONG ENOUGH TO PRODUCE ISOLATED DAMAGE AND
POWER OUTAGES AGAIN AROUND THE PORTLAND METRO. A HIGH WIND WATCH
IS IN EFFECT FOR THIS AREA. OTHERWISE BRISK 15 TO 25 MPH EAST AND
NORTHEAST WINDS WILL ALSO AFFECT THE ENTIRE REGION MONDAY NIGHT
AND TUESDAY...WITH SOME LOCALLY HIGHER GUSTS TO 45 OR 50 MPH IN
THE COAST RANGE AND 35 MPH ALONG THE COAST.

AS WELL. LOW TEMPERATURES WILL LIKELY BE COLDEST EITHER TUESDAY OR
WEDNESDAY NIGHT WHEN WINDS BEGIN TO RELAX. EXPECT LOW TEMPERATURES
IN THE LOW 20S ACROSS THE PORTLAND METRO...BUT TEMPERATURES WILL
LIKELY DIP INTO THE TEENS ACROSS THE REST OF THE WILLAMETTE
VALLEY.

THE STRONG EAST TO NORTHEAST WINDS IN COMBINATION WITH COLD
TEMPERATURES WILL PRODUCE VERY COLD WIND CHILLS MONDAY NIGHT AND
TUESDAY. THE COLDEST WIND CHILLS WILL LIKELY BE IN THE CASCADES
AND IN THE COLUMBIA GORGE...BUT THE REMAINDER OF SOUTHWEST
WASHINGTON AND NORTHWEST OREGON WILL FEEL THE EFFECTS AS WELL. A
WIND CHILL WATCH IS IN EFFECT FOR THE NORTH OREGON AND SOUTH
WASHINGTON CASCADES WHERE WIND CHILL VALUES OF MINUS 15 TO MINUS
25 FAHRENHEIT APPEAR POSSIBLE LATE MONDAY NIGHT INTO TUESDAY
