Patchy Freezing Rain Monday AM, Then the Big Thaw

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!

    31 degs and raining in strawbridge parkway valley adjacent to u s 26

    Yesterday lo 24 hi 33.

    Does anyone know the conditions on Hwy 26 between Banks and Seaside? The ODOT camera shot look OK, but looks can be deceiving.
    Any idea what the temps are?
    I’ve got to get home to Hillsboro and get to work.

    • TimC says:

      Oh, yeah… raining sideways in Ocean Park, WA. Wind from the South. Swirly wind or something, I don’t know what’s up with that. The storm is moving in from the ocean, but the flag is pointing North.

    Ooooppppsss….. Sucks when your live and mix two words together like deep and thick and it doesnt come out like you hoped! LOL!!!

    Roads in Downtown Portland are still a terrible mess. This really surprises me…

    • David B. says:

      Not enough warming yet plus being in the shadows of skyscrapers when it was dry last week would be my guess. I’ve often noticed that even when it’s melting due to mild rain after the marine air comes back, the snow really tends to stick around best in the spots that stayed shaded and got good and frozen earlier.

    • Mark Nelsen says:

      I’m surprised they weren’t plowed…and again, why can’t we use salt just once a year? All day long yesterday roads could have been treated and mostly okay today.

    • W7ENK says:

      That’s kinda what I was thinking, Mark. Once the Interstates and main highways/avenues/boulevards were plowed clear, rather than putting the equipment away they COULD have spent a few hours clearing roads in the center of town — at the very least! I’ve driven a snowplow (when I worked at OHSU), so I know that when it’s slushy, a single plow can clear one city block, three lanes wide in about 10 minutes. Three plows staggered, one pass. Maybe the powers that be were more concerned with lost revenue by plugging up all their streertside parking with piles of snow?

      Still seems ridiculous.

  5. Sapo says:

    Temperature 32 in Tigard, but snow still cold enough for freezing rain to stick, roads icy and precipitation moving in.

  6. Up at Crown Point, the gradient is still strong, but the winds are starting to slack. I wonder if the anemometer is starting to ice up.

    Currently 28 there.

    Here it’s 32 and raining, but it’s not freezing on anything.

    • Jason Hougak says:

      February 20th looks awesome, northly flow out of Alaska and flow briefly out over ocean and back on shore. Check archives of Feb. 18-19 1993 and this looks like the same exact setup. Things look very snowy! 🙂

    • David B. says:

      Could be, but the standard disclaimers about forecasts which are 10 days out apply.

    • W7ENK says:

      I think Mark needs to include this somewhere in the formatting of his page, that’s great!

    • David B. says:

      What’s ironic is that for Seattle, the forecast for Saturday that was the most accurate was the one which was issued 7 days out! Every other one missed the mark (until the GOLU-based show advisory which was issued halfway through the snow event, that is).

    • gidrons says:

      When the GFS spits out a different solution every 6 hours, odds are that one of them will be right. The old “broken clock is right twice a day”.

    • dharmabum says:

      Thanks for the link Jason, it’s good to be forewarned about this kind of possibility. Some of the other comments are so obvious they should go without saying.

    • Jason Hougak says:

      The way this winter is going I’d say it’s totally possible. We haven’t had a NW flow yet or pineapple express.

  7. W7ENK says:

    Temperature hovering right at freezing, everything on the ground is frozen and crunchy, wet spots are slicked over. Some light sprinkles on my way to the bus, things could get interesting.

  8. Brian says:

    Live on top of hill by millplain and Brandt in Vancouver. 31 here and freezing rain. East wind has been blowin again. Cold air not leaving yet

  9. alohabb says:

    Heavy freezing rain falling now in Aloha

  10. JJ78259 says:

    After a beautiful 70° weekend we are heading into another cold blip for 2 days then looks like 8 straight days of 70’s and maybe 80 as spring begins in San Antonio!

  11. Eastman(Parkrose/NE Portland) says:

    East Wind continuing to increase here in NE Portland. Trees are cracking. Windows are rattling a bit.
    Sounds crazy!
    Excited to see what the morning has in store. Been beautiful!!
    Couldn’t the East wind keep things under freezing if it persists tomorrow? Just wondering. Im not too great at this stuff. Lol 🙂

  12. Jack in Corbett says:

    Wind continues to increase here in the Gorge. Gradient now 6.5 with sustained 30’s and gusts in 50’s. Where’s the calming everyone talked about? Temps here never got above freezing today and is 28.4* now.

    Hopefully a better day tomorrow.

  14. orwxguy says:

    Dense fog here in Corvallis… temperatures are a few degrees above freezing, though, so a slow melting continues. Still have lots of snow on the ground and all but the main streets are still mostly buried in snow and slush…

  15. Peter McGovern says:

    11:17pm 2-9-14 @ 1100 feet elev. @ Skyline Blvd near Germantown. Still an icy winter wonderland up here. Icy glaze on top of inches of snow. Got to about 33 degrees today with almost no melting of anything. Now about 30 degrees or less.

    • Peter McGovern says:

      Why is my comment awaiting moderation and everyone else’s seems to be timely? Is it worth it for me to post here?

    • Peter McGovern says:

      Ok …I read the blog rules and see that you have to approve it the first time. I should have read it the first time as I will probably change my name to pmcg and have to be approved again.

  16. Ben T says:

    Bring on more snow!!

  17. Austin-East Vancouver says:

    The snow was turning slushy over here, but has frozen over again and now we have thick fog here as well. so now i have freezing fog to deal with. I have called work to let them know I will not be coming in til after 10 no need to risk it since I know I’m not a great driver in ice and snow.

    • Lurkyloo says:

      Good call, Austin. Be careful, it could still be funky out there after 10am.

    • Austin-East Vancouver says:

      Yea, they said to just take the day off that there was no reason to come in since side roads are pretty bad. By everything is melting pretty good now.

  18. Sifton says:

    dang, 2nd…..

  19. Austin-East Vancouver says:

    First :p
