Chief Meteorologist Justin Stapleton‘s Evening Forecast Discussion:
Dense fog will once again fill back in across the valley and most of Western Oregon tonight. Visibility will be an issue, likely down to a quarter mile or less for most of the night. Take care on the roads as lows will hold in the low 40s which will also be right about where the dewpoints will settle for the night.
Tomorrow, it’s more fog overall for the Southern Willamette Valley with not much expectations for seeing any sun breaks. Highs will likely sit near 50. Elsewhere, some partial sunshine before a weak disturbance slides across the state. The weather models have been consistent with squeezing out a few showers around dinnertime, so I’ll metion an isolated chance but mainly just increasing the clouds. Snow lines will be below the Passes so some light snow showers on the roads by later in the day.
By Friday, another storm moves a front across the region, and a stronger dip in the jetstream will pull in some cold air along with the rain. Into the weekend, including the Duck game against Utah with a 1p kickoff at Autzen, more showers are likely, along with a shot of colder, Canadian air. So expect highs to drop back to near 50 and freezing levels dipping below the Passes to around 3000 feet. Accumulations will be around 3-5″ on Saturday but winds will be very breezy so expect blowing snow in the mountains both Friday and Saturday.
Sunday and Monday, showers taper off, but the cold air is stuck. Highs won’t get out of the 40s for most of the region. Looks like we’ll stay chilly into next week as well!
Have a great Thursday!
