Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
The Air Stagnation Advisory continues through early Thursday morning for the Central to South Willamette Valley, including Corvallis, Albany and Eugene/Springfield areas. Light winds and the inversion is still trapping pollutants near the ground, so wood burning unless exempted, is still banned until we get some movement in the airmass. It won’t be tonight as light winds and mostly clear skies should allow for some patchy freezing fog with lows again falling into the mid to upper 20s.
Highs will stay near 50 over the next couple of days with clouds increasing both Wednesday and on Thanksgiving, but no rain or snow to deal with across the state. The East Coast will continue to stay messy with snow and ice from the Mid-Atlantic to Northeast, heavy rain across parts of the South.
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, cold air plunging south into the Northwest, along with storm systems from Sunday through Tuesday. Snow lines are forecast to fall into the foothills and maybe push below 1000 feet. How much moisture will still be around once the really cold air gets there is the real question, but we may be seeing some valley flurries for the first time this season!
Have a great Wednesday!
