A dense fog advisory is in effect this morning for the Willamette Valley, north Oregon coast and the east side of the Columbia River Gorge. Also an air stagnation advisory will be in effect for much of Oregon over the weekend. Some places may not see any sunshine while trapped under an invisible lid known as the inversion. The Dalles, for instance, may stay in the upper 30’s this weekend.

Portland and surrounding temps will be tricky. If you’re trapped in the inversion then your temp may max out in the low to mid 40’s. If your clouds break then you may feel the warmth of the low 50’s.
Your best bet for sunshine is going to be at the coast, better clearing with temps reaching low 50’s. Or try the mountains and get above the inversion.

Air stagnation advisory: Willamette Valley until Monday
