December opens the door to some very cold weather! The table below is from last night and this morning, where you can see that we just passed the 15th hour of freezing weather here in Eugene. The full weather alert is located below…….

…ARCTIC BLAST HEADED TOWARD NORTHWEST OREGON AND SOUTHWEST

WASHINGTON LATE TONIGHT AND SUNDAY…

A COLD SHOT OF ARCTIC AIR WILL ARRIVE LATE TONIGHT AND SUNDAY AS
AN ARCTIC FRONT SWEEPS WEST ACROSS THE CASCADES INTO NORTHWEST
OREGON AND SOUTHWEST WASHINGTON. DAYTIME TEMPERATURES WILL REMAIN
IN THE 30S IN MOST AREAS OF THE WILLAMETTE VALLEY AND CLARK COUNTY
SUNDAY…BUT WILL STRUGGLE TO RISE ABOVE FREEZING ON MONDAY.
OVERNIGHT TEMPERATURES SUNDAY NIGHT WILL FALL INTO THE TEENS AND
TWENTIES ALONG WITH INCREASING EASTERLY WINDS.

WIND CHILL VALUES WILL DROP SIGNIFICANTLY SUNDAY NIGHT. IN THE
COLUMBIA GORGE…WHERE WIND GUSTS UP TO 50 MPH WILL COINCIDE WITH
TEMPERATURES IN THE UPPER TEENS TO LOWER 20S…WIND CHILL VALUES
WILL DROP TO NEAR ZERO AT TIMES. SIMILARLY…WIND CHILL VALUES IN
THE SINGLE DIGITS CAN BE EXPECTED IN THE PORTLAND METRO AREA AND
CLARK COUNTY FOR AREAS NEAR THE GORGE. FINALLY…TEMPERATURES IN
THE CASCADES WILL BE IN THE SINGLE DIGITS WITH WIND CHILLS 10 TO
15 DEGREES BELOW ZERO AT THE PASSES AND RIDGES.

SCATTERED SNOW SHOWERS ARE POSSIBLE IN THE CASCADES AND THERE IS
A CHANCE THIS SYSTEM COULD BRING SOME LIGHT SNOW TO THE VALLEYS.
THIS WILL DEPEND ON HOW THE SYSTEM DEVELOPS AND HOW MUCH MOISTURE
IS AVAILABLE…BUT NO SIGNIFICANT AMOUNTS ARE EXPECTED.

IT APPEARS THAT LOW LEVEL COLD AIR WILL REMAIN IN PLACE OVER
SOUTHWEST WASHINGTON AND NORTHWEST OREGON THROUGH TUESDAY…THEN
SOME WARMING IS EXPECTED…ESPECIALLY AT NIGHT. TEMPERATURES
ALONG THE COAST WILL BE THE FIRST TO MODERATE…WITH SOME WARMING
POSSIBLE AS EARLY AS TUESDAY.

YOU SHOULD TAKE ACTION NOW TO PREPARE FOR THE VERY COLD WEATHER.
