... Unseasonably mild weather to give way to much colder
temperatures and possible low elevation snow this weekend...
For the past several days... southwest Washington and northwest
Oregon have been experiencing record setting warmth. However... a
major weather pattern change is on the way. A sharp cold front is
expected to move through the region from the north on Friday and
Friday evening. Snow levels will be high initially... but will
fall sharply behind the cold frontal passage. Post frontal
showers may fall as a mix of rain and snow down to the valley
floor at times Friday night and Saturday. Precipitation is
expected to end by Saturday night. Gusty offshore flow is then
expected to develop Saturday night and Sunday. This offshore flow
will usher in frigid conditions as it pulls in air from an Arctic
air mass on the east side of the Cascades.
