You may be hearing rumors of something frozen appearing in the western valleys of Oregon/SW Washington Monday morning? I think it’s pretty unlikely (as of 1:30pm Sunday) because I don’t think ANYTHING will be falling out of the sky…weatherwise at least. I can’t account for dogs/cats/frogs etc…
I also don’t think the Monday morning commute will look like this…but it’s a cool pic I found online while relaxing with a warm drink:
- It’s a cold day! Airmass streaming out of the Gorge is the coldest this season. Only 40 at 1pm in Portland. Highs only around freezing in the western Gorge. Lots of ice likely forming on waterfalls! (hint…please send pics to firstname.lastname@example.org)
- Another clear and cold night tonight. A few upper teens again in coldest outlying areas
- Clouds thicken up right after sunrise, it’ll be briefly sunny Monday AM
- A shower is POSSIBLE after 10am or so. Most likely it’ll stay dry
- At that point it’ll be too warm (that’s IF a shower develops) for liquid raindrops to freeze to objects
- It’s too warm overhead for give us sleet/snow, anything falling would be liquid
So the point here is that most likely Monday will be dry, but maybe a shower shows up midday or beyond. Too “warm” at that time for freezing rain. It will be a very chilly day with the cloud cover…highs the same or even a notch cooler than today! Note several model forecasts of precipitation placement at 10am…looks pretty dry doesn’t it? Click on each for a better view.
Now Tuesday night, when a more typical wet system arrives, could be a much bigger issue in the Columbia River Gorge. It’ll be near/below freezing at that time so we could be looking at some freezing rain/ice storm action at that point out there. More on that later
By the way, so we’re all on the same page, freezing rain is liquid rain that falls into a below-freezing airmass near the surface. It freezes on contact, forming an icy glaze.
