A Winter Storm Watch will take effect Wednesday evening for all of Western Oregon, and continue until Thursday morning. The watch has been put into effect due to the possibility of freezing rain early Thursday morning.
Clear skies across the region Tuesday night will make for chilly temperatures to begin Wednesday. At night, clouds work like a blanket helping to keep heat at the surface of the earth. As the clouds diminish that heat radiates away into space and surface temperatures drop. Because of this many locations should expect lows to hit the lower 20s, and a few places may even be in the teens.
Black ice is possible Wednesday morning. Any standing water on the roads will freeze with the cold overnight lows. The wise morning commuter is planning to leave early and give his or herself extra time to get to work or school.
Wednesday afternoon will see clouds begin to move into the region with the arrival of our next storm. Highs on Wednesday will high the mid 40s and lower 50s. Rainfall will start after sunset on Wednesday and possibly turn to freezing rain by Thursday morning. Ice accumulations will be small—less than a tenth of an inch—but enough to cause traffic delays and problems Thursday.
