We’ve seen east wind blowing through the Columbia River Gorge most of the past week. Now a cold airmass is sitting below about 1,500′ at the west end of the Gorge and 4,000′ at the east end. The air moving in overhead has a freezing level around 8,000′!
As a result, a mix of freezing rain at the west end of the Gorge and freezing rain, ice pellets, and snow will fall once precipitation arrives later tonight. It won’t be a lot, but just a few minutes of freezing rain can make I-84 an icy mess. There will be no switch to a warming westerly wind tomorrow, which means temps will only climb a notch or two above freezing. The good news is that the wind should turn gusty westerly on Wednesday, so temps may jump to around 50 at that time.
Here in the metro area we sure had a gray day today! Quite a change from the bright sunshine over the past few weeks.
I don’t see a whole lot of rain coming up, maybe 1/2″ to 3/4″ before we dry out Thursday morning. Still, we’ll take what we can get since it’s been such a dry winter!
