Today’s slow thaw was VERY slow. PDX hit 33, other parts of the metro area were up in the 33-37 degree range. But now we are seeing plenty of refreezing because skies have cleared out. Snow cover on the ground and a clearing sky means temps can easily drop back to freezing. Around 9:30pm this semi truck went flying off the I-205/I-5 interchange near Tualatin:
There will be no warming south wind overnight, and the only thing that would keep temps near/above freezing would be thick cloud cover moving in. Don’t count on that.
Here is the plan for tomorrow morning:
- Most side roads will be icy, or at least have lots of leftover slush/snow on them
- Freeways should be mainly okay though
- I don’t expect a widespread freezing rain event
- But some showers will arrive after 8am, and in some spots those will fall as freezing rain.
- Will you be able to tell the difference between a few spots of freezing rain and icy streets left from overnight freezing…I doubt it. Not much different from what we have right now.
- By 10am temps will be rising above the point which liquid rain would freeze to roads anyway (30-31) ) so then we are out of it, including the far eastside of town (Troutdale/Gresham)
In the Gorge, it’ll stay frozen all day, except the far west end near Corbett and above Washougal which will get warming southerly wind in the afternoon/evening. So maybe 1/2″ ice accumulation from Multnomah Falls to Hood River. Lighter amounts at The Dalles.
So drive carefully tonight and tomorrow morning. If you DO plan to go to work, rest assured that roads will be MUCH better in the afternoon and evening. Really!
