The most potent cold front of the week so far is bringing widespread rain to the area currently and rain will increase through the evening. Showers will begin tapering off by Thursday morning with only the coast and Cascades seeing the chance for showers all day. By Thursday afternoon the Cascade passes could pick up two to four inches of snow while Crater Lake and Diamond Lake could see up to six inches. Those traveling over the higher Cascade passes should be prepared for winter driving conditions. Snow levels will drop from 5,000 feet tonight to 3,5oo feet by Thursday morning, though most of the precipitation will be over by the time we see the lower snow levels. Snow levels will climb during the day Thursday and Friday back to 6,000 feet. Our next round of rain will arrive Thursday afternoon and evening with showers ending early Friday morning. Friday for most areas will see dry conditions as high pressure builds in, the Cascades and the coast will have the best chance to see any shower activity.
An even stronger cold front than the one tonight will arrive Friday night into Saturday with the heaviest rain falling during the day Saturday and a few showers continuing into Sunday. Winds will also pick up Saturday and we could potentially see gusts up to 40 mph at the coast, ridges and east side. Snow levels during the day Saturday will be above pass level around 6,000 feet but drops to 4,000 feet by Sunday morning which will impact the higher Cascade passes. Though by the time snow levels drop most of the precipitation will have moved out of the area.
Next week a high pressure ridge builds back into the area and this will bring sunshine and mild afternoons with west side valley fog and low clouds.
Thanks for logging on and have a great evening!
