9am: Incoming Showers = More Spotty Freezing Rain

I hope most of you in the central/east part of Portland chose to skip work/school today!

That first band of freezing rain passed through the metro area before sunrise, but was light enough that most roads don’t appear to have been affected much.  Don’t be fooled, check out radar…

Here come more showers and they look quite wet this time!  They are sneaking in due to that ridiculous huge gap in the radar coverage off the Oregon Coast.


Except for the timing of the heavier rain speeding up, the rest of the forecast is still on track.  Let’s check current temps:


I hope you enjoy my graphics talent…  The yellow shows the areas that are at risk of widespread road icing BEFORE NOON.  This is roughly the “blue area” I showed on-air last night and in the previous blog posting.  This is going to quickly become an event centered on those areas that typically see cold outflow from the Gorge.  I find it very interesting the top of Mt. Scott appears to be busting out of the cold air.  This tells me the cold layer is VERY shallow and will mix out easily anywhere in Clackamas/Washington/Clark counties.  I left Clark county in the “scary yellow box”, but even there after noon it should be warming above freezing.

To summarize

  1. In the next two hours a light glazing of ice is still possible anywhere in the metro area still below freezing.
  2. But for a large part of the metro area (outside of yellow area above+most of Clark County), you will be “in the clear” after the noon hour.
  3. Ice Storm is still on for central to eastside of metro area…roads likely turn very icy the next few hours there.
  4. Loading of ice on trees/powerlines will become a big issue this evening and tonight east of I-5 in Multnomah County, especially east of I-205

    Have the weather man and traffic to turn on their head light so other drivers can see them

  2. Lee Wilson says:

    Mark, there is a problem starting to occur.
    The ground which is frozen can not take in the water.
    Could this cause a flash flood?

  3. Lee Wilson says:

    Are you Pumped For the weather?
    Emergency Water Pump: https://youtu.be/qzo3lN3jhZA

    If ever your city water system shuts down you can use one of these on a rainy day..5 gallon bucket and a hose..

    Or you can use a larger one and try and pump water out of your house.

  5. Lee Wilson says:

    Winter Concert at Castle Rock Washing School has been canceled due to unsafe road conditions s…must be real nasty in areas.

  6. Lee Wilson says:

    Dang from 33 to 36 in less than 2 hours.

  7. John says:

    Downtown and close in East Portland, rain is not currently freezing, temps above freezing, plenty of standing, puddly water.

  8. Max in Fairview says:

    Have a good glazing here and only looks to get worst into the evening. Sidewalk very slippery.

  9. Beth says:

    Hayden Bay Marina. Raining hard and icing on everything.

  10. Couv Res says:

    30 now…thought temp was supposed to go up??

  11. Claire D Gilroy says:

    Pouring in Salmon Creek and temp has dropped to 30. Hasn’t made it past 31 yet today.

  12. Lee Wilson says:

    We are getting ..Snain….eh…can I make that an official weather term?

    Because its not snow and its not rain..its bother all mingled in to one drop….

    So..we have..Snain…

  13. Longview 400 ft says:

    Currently 30.2
    The temp has dropped 2 degrees since an hour ago and now freezing rain is occurring. At least on the railing of our deck. I have been out in the yard all morning taking down Christmas lights (Since 7:30 am) and now the rain is turning to ice.

    • Andrew Bartholomew says:

      I too was wondering if the moisture in air might drop temps a degree or two. In Downtown Portland, looks like a cold rain but right on the border temps wise.

  14. Couv Res says:

    31 in Vancouver Heights area with a steady freezing rain. Nice layer of ice forming on the power lines.

  15. Diana F says:

    I want to cry….there’s moisture falling out of the sky that is “washing” the snow off the trees, from 150′ in the air on down……slowly but surely…….soon……my incredibly WHITE Snow Lodge neighborhood will be just icky and gloomy looking and GREY = Dirty. Blech.

    It’s been pristine for 6 days straight! I still have 5″ of snow in the yard~!

    Say it isn’t so………THEN……..ask when is the next go-around of crazy weather!

  16. gggcorno says:

    Interesting – temps here (SW Beav/Aloha) dropped from 35 to 33 in about 15 minutes once the heavier precipitation arrived. Still some dewpoint spread to go. Might it yet freeze?

    On the warm side, I can see a tiny piece of grass appearing in my otherwise white lawn.

  17. Mama Druid says:

    Ha! As soon as I posted that nothing is happening, it started sprinkling! Ever so lightly.

  18. Jeff garden home 250 says:

    Light rain and 35 in Garden Home. Not freezing on any surfaces, but not much melting on the road yet either. Looks like Mark was right for us. We are just outside the yellow zone.

  19. W7ENK says:

    NWS is slowly rolling up the mats. We should see more of these coming out soon. I guess it’s game over…

    1242 PM PST TUE JAN 17 2017


  20. Mama Druid says:

    Nearly 1:00 pm and nothing happening in Happy Valley. The Wunderground app keeps saying there is precipitation, but there has been zero since I woke up at 5:30. Unless you count melting icicles!

  21. JJ78259 says:

    Funny it seems like the overall feeling on the blog is very happy to see 45 degrees and steady rain! My how things change.

  22. esmewwax says:

    Corbett- no rain yet, 26 degrees, right next to the river the wind is still pretty brisk- gusts in the 70’s at Vista House (3am there was a 102mph gust!). Tucked in snug, waiting for that rain…..

  23. Jake-(Gresham near Nadaka Nature Park) says:

    May I remind everyone that Mark has clearly stated the heavy freezing rain starts in the PM hours. This is just getting started and we have people calling this a bust? Does anyone recall there’s an evening commute and only about 3 hours of daylight left. )_+

    • Laura -- Weather Group Outcast says:

      This is why i left downtown at noon… i’m not getting stuck there, no way in hell!

    • Lee Wilson says:

      Our temps are going the opposite from freezing we would have to decrease just as fast. To get freezing rain.but if were at 36 and rising. Well….it can’t do Freezing rain…but I also been around long enough where mother nature’s pulled a whammy.

  24. Sapo says:

    I think westside and downtown PDX avoid an ice event…Temps seem to be above freezing pretty much everywhere besides east metro area, they could be in for a significant event with this heavy precip moving in

  25. Diana F. says:

    If I hold my phone just right, I see a yellow boot!

  26. BruceInTroutdale says:

    Winds died in Troutdale except for right along the river/I84. Up out of downtown it’s gone calm with 31-32 on most stations. The little rain we’ve seen is NOT freezing on anything. Looking like a major forecast bust in progress unless the winds kick back in – or we get serious evap cooling.

  27. Lee Wilson says:

    We dodge the bullet I think.

  28. PDX-Hawks says:

    Was just out-n-about in Aloha/Beaverton. Wet roads, rain but still slippery where ice is still on roadways. Truck said 32 but my weather station has me at 35. Thank goodness the westside missed this one. If you gotta get out today, drive safe and leave plenty of distance.

  29. W7ENK says:

    Just started raining in Milwaukie, freezing on contact to everything EXCEPT bare road surfaces. Maybe it’ll stay this way?

  30. Paul D says:

    And Mark takes another jab at that radar gap!

  31. I’ve been watching the temps on http://wxug.us/23k45 all morning and most temps around are already well above freezing except right near the gorge. I think most of the area avoids the ice. I just hope the rain can wash away a lot of the ice by the evening commute. Wet ice is almost as bad as freezing rain, but I’m guessing it breaks quickly when driven on.

    • Jake-(Gresham near Nadaka Nature Park) says:

      Dusk my friend. Dusk, sun angle is really low this time of year. We’re going to not get much more solar radiation for today. I hope most of my family and friends stayed home. Stubborn folks they all are. Hhmmm… wonder what that makes me. )_)

  32. gggcorno says:

    Condensing water vapor is now falling in Beaverton. 35 degrees, so no freezing rain. However, with two inches of dense ice on the street, that extra bit of liquid water on top can’t help but make driving a bit more sporty. I’m not going to drive for a while.

  33. K. PacificNW says:

    Last night it was “will be the worst ice storm since 1996.” Now I see only unfrozen rain on the NWS radar, and it says “high of 41.”

  34. Alohabb says:

    Steady rain falling in Hillsboro.

  35. JJ78259 says:

    Hey Weather Dan when was the last time Portland did not hit 50 in January?? Has that ever happened?

    • WEATHERDAN says:

      I live in Salem and I can’t recall that ever happening down here. Closest was 1979 when we only hit 50 once that month. As for PDX you need to ask somebody who live up there. Peace.

    • Roland Derksen says:

      The last time I didn’t see it hit 50F in a January here in Vancouver BC was in January 1979. We came close (got up to 48F). The odds of that happening again this time are getting small. Presently 45F with rain.

  36. Alohabb says:

    Appears Aloha/Beaverton is out of the crosshairs. Let the melting begin!

  37. W7ENK says:

    Woke to a very light glazing of ice on everything this morning, including my windshield. It was just enough to call off for the day and go back to bed. Sitting right at 30 degrees now, and with this next batch of showers about to push in, I’m happy to be at home safe. I wouldn’t want to get stranded in Downtown or have to abandon my car at the Park N Ride overnight.

  38. NathaninSE says:

    Currently 32.7 where I’m at. The temps seemed to have raised 3-4 degrees in the past few hours. I’m starting to doubt the freezing rain!

  39. AK1 says:

    What about commute on Wednesday morning in the west hills (Miller Rd.)? Will it be icy from the freezing rain this afternoon?

    • AK1 says:

      We did not have any freezing rain / new ice forming. So, I assume it will be better for commuting to work tomorrow morning. Temperature here is above freezing.

  40. Windsday says:

    The sun is out and the birds are singing. Oh wait the birds part will be in a month but the sun has definitely come to town.

    It’s a toasty 36F and not a sign of rain anywhere. Everything is running like clockwork around here. No delays or anything.

    Traffic is the usual workday stuff.

  41. Donaleen Kohn says:

    Huh, I thought you adjusted the weather map as requested. I wanted to thank you for that.

  42. pappoose in scappoose says:

    The ice man cometh!
