Final Freezing Rain Update This Evening

Tuesday, 9:15pm…

The highlights:

  • There will be a brief period of freezing rain (glaze ice) anywhere between the Coast Range and Cascades at the lower elevations Wednesday morning, possibly as early as 6am, but no later than 9-10am.
  • It will not last long (a few hours at most) away from the Columbia River Gorge.  No matter what happens before 10am, after that time it’ll be too warm for any new areas of freezing except in the Gorge.
  • It only takes 5-10 minutes of freezing rain to turn a dry road into an ice rink.
  • The afternoon commute should be fine with temps well above freezing away from the Gorge.
  • The Gorge won’t thaw until late afternoon or evening, that may include the far eastside metro near the Columbia River (Troutdale/Camas)

What’s New Since the Previous Posting at Noon?

  • Timing of precipitation has been sped up slightly on some models, but not on others that came out this evening, it’ll be sometime between 6am-10am.  Sorry, I can’t nail it down any more than that since our models have some disagreement.  The main theme is LIGHT at first, just sprinkles to very light rain.  Some of our models are still showing no precipitation until 9-11am.
  • Temperatures look cold enough now near/below freezing before 9am, that whatever falls should freeze just about anywhere.  There may have been some doubt about that earlier, but not now.
  • Best case scenario:  Morning commute just sees patchy icy areas with sprinkles, temps warm a few degrees, then regular steadier rain kicks in after 10-11am. with not too many road issues.
  • Worst case scenario: An area of light rain moving right over the Valley at 6am, depositing ice all over roads and the morning commute is a hellish event with cars sliding all over the place before melting after 9-10am.
  • Whatever happens should be somewhere between these two scenarios.

If ever there was a time to keep an eye on weather surveillance radar, tomorrow is it!  My preference is this one.  I don’t know why, but I usually go to that link.  Of course we’ll be tracking things here at FOX12 starting at 4:30am.

And I’ll be back online around 7-8am as well…

    Freezing rain advisory for North Willamette Valley now till 4??

    • Tyler Mode in Battle Ground says:

      Yes in pockets. With little to no gradient, the valleys will have a hard time mixing out. MOST areas will warm quickly, but if you are in one of those valleys…

  2. Vinnay says:

    31 in gresham

  3. W7ENK says:

    All areas are above freezing this morning, with the exception of only a few stations mainly South of PDX metro, and of course in the immediate Gorge outflow areas like Gresham and Troutdale.

    The ice threat is gone! \^_^/

  4. Ben T says:

    There’s something peculiar and coincidental I thought I would mention. I received a political email from a guy named “Rob” Engstrom with the subject line “Are You In?”

  5. Darlene in Boring says:

    It has been 33 here since I got up at 5am, just dropped to 32 and it might drop more as sunrise approaches. I guess it is just a waiting game to see if we warm up enough before the moisture makes it to the east side.

  6. W7ENK says:

    Let the back tracking begin!

    NWS has removed the threat of ice for everything South of Wilsonville.

    • JJJ97222 says:

      Yes a little farther south in Austin 56 degrees with a high of 78 should be a good time on 6th street tonight. Quite foggy right now but lifting

  7. Ben T says:

    From AFD: “Saturday morning through Tuesday evening…an upper trough will result in showery weather this weekend with lowering snow levels.” Hmm?

    • W7ENK says:

      Yup, lowering from the 8-10,000 feet it’s at now down to the ~2,000 feet it will be at by the weekend. Welcome back to our typical wintertime doldrums!

  8. W7ENK says:

    My temperature leveled off and stayed at 34 degrees all night. No precip yet, but there will not be any ice here when it starts raining.

  9. Tyler Mode in Battle Ground says:

    Temp is 31.9 here and just recorded my strongest wind since the 9th!

    13 mph!

  10. runrain says:

    The Milwaukee Dome has grown into a Godzilla monster! :((

  11. alohabb says:

    34 here now so i would sat threat is gone in westside n

  12. 31.4 here as of 5:45. Here is my thoughts
    Anywhere could see spotty ice between now and 7-8 am
    After that areas with S wind begin to moderate, no problems there
    East of I-205 could see ZR until noon or so. Temps are still falling with STRONG east wind. Basically just waiting on precip out here

  13. chiefWright (Marquam) says:

    Let the morning begin!
    ***Surface temps in the valley are all hovering around freezing.
    ***Lots of echo on radar but most of it coming & going over the valley so I’m guessing it’s mostly virga for now.
    ***Still to early for good roadcam visuals, but I don’t see any obvious ice-glare at Grande Ronde yet; that’s where I’d expect it first given surface temps & radar.
    ***Wind at Biddle Butte (crown point area) is dropping, but wind at Troutdale is increasing. Most of the wind barbs in Portland are turning towards the gorge where they’ve been nada for many days. PDX-DLS gradient isn’t changing much at all
    ***KPTV upper tower temps dropping, and getting closer to middle & lower, which are both just below freezing.

  14. Beaverton-mom says:

    Thank you mark. I use this blog and website for travel info daily. Little icy in sexton mt. But nothing spectacular…….would like a little snow.

  15. Interesting OBS here.
    The temp has fluctuated between 32 and 34 all morning, but after getting up to 34 just an hour ago, it’s dropping again and back down to 32.3 now as the east wind has ramped up again. It seems each time the wind kicks up, there is enough of a cooling effect to it to keep temps around freezing.

  16. Tyler Mode in Battle Ground says:

    32.1 here in BG, pretty warm really. I still think if the rain moves in early enough it will freeze to surfaces since they have been cold for so long. But, it sure won’t last long.

  18. I was just woke up due to some tremendous burst of winds moving through the area. My sensor says 45.1, but they sounded stronger than that. I assume most of Gresham and Troutdale may have been woke up by this too…. If these kind of gusts continue we’re going to see tree limbs(possibly trees) damaged and possible power outages.

  19. Marcus says:

    35f not sure about freezing rain here in la center!

  20. W7ENK says:

    Expect this issue to arise again tomorrow morning once the moisture moves over our area. Blame the dome, or the dry Gorge outflow, whatever… just don’t blame me!

    BTW, this image (from last winter) is not photoshopped.

  21. Marcus says:

    00z best chance for snow is when we are in the northerly flow and a low slides down other than that it looks chilly and mostly dry to me with the bulk of the cold going well to the east:/

  22. Kent Estep says:

    Since I have absolutely zero confidence that this ‘storm’ will produce anything remotely exciting I thought I would share this from the LA CBS affiliate…

    As for what kind of weather in Los Angeles this storm chasing vehicle will be pursuing, I’m guessing…fog ? Drizzle ?

    I can’t wait until we get ‘hyper-localized-data’ here in Portland…

    I guess when the weather is as boring as it is in LA, you have to compensate for it somehow…

  23. W7ENK says:

    As clouds are moving in, temperatures around the area are on the rebound! Back up to 34 at PDX. No ice for you!!! Come back next year!!! :mrgreen:

  24. Biddle Butte new peak gust 75mph joining Corbett with Hurricane force winds tonight.

  25. Marcus says:

    Is everyone ready for the arctic blast to be revealed on tonights00z euro???? :))) sorry just trying to stay positive!

  26. Danny in Troutdale says:

    Having trouble posting or something?

  27. Hello? is anyone seeing this?

  28. Ron says:

    Either way the gorge is going to get nailed especially here in Hood River

  29. Ben T says:

    It’s kinda sad that some of us are excited about freezing rain. It’s not snow! But hey… It’s just weather I guess… Nothing that should make you feel unhappy.

  30. Brad says:

    “I don’t know why, but I usually go to that link.”

    Closet fan of War Games growing up? Reminds me of NORAD.

    Thanks for the updates – ladies and gentlemen, time to place your bets. The windows are closing….

  32. 73rd! Thanks, Mark..

    “Worst case scenario: An area of light rain moving right over the Valley at 6am, depositing ice all over roads and the morning commute is a hellish event with cars sliding all over the place!”

    • W7ENK says:

      Yup, that sounds pretty worst case! 😆

    • lilfoot123 says:

      So fun weather wise!!😜 Thankfully I will not have to go anywhere until after 10a! The dr. would like my blood! Nothing serious just to make sure my thyroid is functioning well! She also tests for the Vitamin D deficit too! Anyway! I will stay under the porch this time! Five years ago with the broken ankle we had freezing rain & I should have looked at the garbage can as it was freezing drizzled! I was talking on the phone to my mom & almost fell off the porch slipping on the icy exposed porch deck! That was the end of iPhone #1! All worked except the camera as I threw the phone at the door mat! I’m now on iPhone 3GS #3! Anyway stay safe all!
