Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
We’re still under a dry and cold airmass over the next couple of days. As expected, air quality is being negatively affected, so much so, an Air Stagnation Advisory has been issued through early Thursday morning for the Central to South Willamette Valley, including Corvallis, Albany and Eugene/Springfield areas. Light winds and a “lid” on top of all this valley air has health officials also banning any wood stove burning unless you have an exemption. Tonight, light winds and mostly clear skies should allow for some patchy freezing fog and a slippery AM commute with lows again falling into the low 20s.
A storm is drifting north offshore into Western BC but will drag a cold front close to the coastline tomorrow evening. I’ll mention a slight chance for some showers at the coast, while inland, it won’ t have much of an effect. Highs will stay in the low 50s over the next couple of days with clouds increasing both Wednesday and on Thanksgiving. While travel delays won’t be an issue in Oregon, the East Coast will be dealing with heavy rain, snow and ice up and down the coastline.
Friday will also stay dry with mostly cloudy skies so chilly for those early morning Black Friday deals and around 50 for kickoff for the Ducks and Beavs in this year’s Civil War game. Heading into the weekend, though, changes are on the way. In fact, we’ll see our first rain chances in well over two weeks (except the trace amounts from freezing fog) late Saturday into Sunday with a storm coming in the from the Gulf of Alaska.
Indications are for a major shift in the weather next week, a plunge in the jet stream into California, and cold air along with storms coming in off the ocean might bring our first chance for some low snow, down into the low foothills. It’s still 7 days out, but the models have been very consistent for calling for a good old fashioned “Arctic Blast” for most of next week.
Have a great Tuesday!
