ICE STORM ARRIVES LATE THURS: Getting a lot of questions about the pending ice storm for n.w. Oregon & s.w. Washington. This thread should answer some q’s, including:

1) When will it turn icy?
2) How much ice will accumulate?
3) Roughly when will it thaw out?

#PDX #ORwx #WAwx Between this afternoon & eve, modified arctic air will surge through the Gorge & spread across the Portland metro area. Temps will drop into the 20s & teens / wind chills in the single digits & maybe below zero. Cold air spreads across western valleys & coastline tonight.

ICE STORM A FEW DAYS AWAY: The coldest air of the season will spread west of the Cascades between late Wednesday & early Thurs. Many cities in our western valleys will be locked in by freezing air through at least Fri. Temps will gradually warm up this weekend. #PDX #ORwx #WAwx Initially, cold air will spread all the way down the Willamette Valley & out along the northern Oregon & southern Washington Coast. Eventually, a warmer weather system will erode the cold air away, first along coast, then southern valley, & last in metro area. #PDX #ORwx #WAwx

The Portland/Vancouver metro area is ~ 3 days out from COLD air arriving, and about 4-5 days out from snow transitioning to freezing rain. Ice storm possible Friday. Will know more by Tue/Wed regarding how much snow/ice is coming and who could get hit hardest. #PDX #ORwx #WAwx Image Let’s go over what we know: arctic air will pour across the interior Northwest Wednesday, and will spread west of the Cascades Wednesday night / Thursday A.M.

Happy Sunday, all! Wanted to give everyone as much of a heads up as possible about this week, since many will be traveling in the days leading up to Christmas. Some kind of snow/ice event is possible in the Portland metro area, Gorge & Cascade Foothills Thur-Sat. #PDX #ORwx #WAwx WEDNESDAY: Starting in afternoon / evening, a cold east wind will be cranking thru the Gorge and across the Portland / Vancouver metro area. This modified arctic air will prime the region with sub-freezing air, setting the stage for a winter weather event Thursday/Friday. #PDX
