Details for Saturday, January 1, 2022

PORTLAND, Ore. (KOIN) — Our stretch of frigid temps continues Saturday as this modified arctic airmass sits over the PNW. Highs will again be well below normal, in the mid-upper 30s in Portland with sunshine for the afternoon.

Saturday starts out dry and foggy with partly sunny skies. 

Next chance for rain is late Sunday morning. That begins a relatively “warmer”, wetter trend with temps in the mid 40’s. Looking out to January 4-6, there’s a possible set up for an atmospheric river with a southwest origin. We’ve seen this before. Cold and snowy turns to warmer and way-too-wet. At this point it appears snow levels could rise to 5,000 feet for the middle of next week.
