Smoky skies should persist across Western Oregon for another day before a wind shift helps to improve Air Quality. The improvement is short-lived however, by the weekend warmer weather arrives and skies will fill with smoke again.
The Willamette Valley will begin our Wednesday under a lot of cloud cover. Sunshine should burn the clouds off around the noon hour. The afternoon will then see blue skies overhead. Highs will warm to the mid to lower 80s. On Thursday, a few early morning showers are possible—meaning before sunrise. Otherwise the day will be dry. High temperatures will only warm to the mid 70s under mostly cloudy skies. Friday and the weekend should see temperatures to gradually warm. 90s are possible by next week with smoky skies filling the region.
The Oregon Coast has a few more days of morning fog and low clouds. Wednesday, Thursday, and probably Friday will start under overcast conditions. Sunshine is expected to appear for the afternoons, though the cloud cover will not dissolve away entirely. Highs should drop a few degrees as well, only reaching the lower 60s on Thursday. This weekend, warmer and drier air fills the Coast. This should diminish the opportunity for fog in the mornings as well as help to warm many locations into the low 70 degree range.
The Umpqua Valley has more sunshine in the forecast, though Wednesday morning will likely start out a bit on the gray side. Despite the morning clouds, sunshine will burn through and highs will warm into the 80s by the afternoon. Local fires around the area do keep skies fairly smoky and air quality between “moderate” and “unsafe for sensitive groups.” Thursday’s highs will be a bit cooler with temperature sin the upper 70s, but this cooldown is short lived. By The weekend mid to upper 90s are possible.
