4pm: Freezing Rain (& Rain) Ending: Icy Spots Possible Westside Tonight

That wasn’t real exciting…just some light rain this afternoon for most of us.  But some spots of freezing rain on the west side of the Willamette Valley.  Had a few reports of freezing rain in McMinnville, Lafayette, Dayton, and some other patches in western Washington county.


As you see on the radar, rain of any sort is about to end as our weak weather system moves on east.

The issue tonight may be the usual case of skies partially clearing behind a cold front; probably only on the west side of the valley again.  Since temps are within a few notches of freezing, any clearing means icy spots could easily develop on roads in those areas…be careful out there later tonight!\

I don’t see a widespread warming southerly wind tonight, but some spots will randomly pop up temp-wise.  I see some mid 40s over on the SE side of the metro area where southerly wind has arrived.  The rest of us stay in the 30s tonight.

    Well… that didn’t last. Looks like any chances for a brief inch or two of lowland snow on Friday are out.

  2. Marcustheweathernut says:

    12z gfs= more boring weather!!!! Ugh!!! Brief cool trough then boring!!! And dry, not good for skiers. Glad I didn’t get a pass this year…. It’s still eary, but long range models look dry as well!!!

  3. boydo3 N Albany says:

    The long range forecast maps do NOT look good for the ski season. Wonder if I can get my money back on that season’s pass.

  4. ocpaul says:

    50 degrees, cloudy, calm. “I’m yawning, I’m yawning some more and zzzzzzzzzzzzz, zzzzzzzzzzzzzz.

  5. shared this on the facebook group, but i know not all of you are on there so ill share it here too, http://earth.nullschool.net/

    its a real-time, interactive wind map of the globe. click on where it says Earth and you can change the parameters. height of the winds, time (can go into the past and projected) as well as different map projections. its pretty hypnotizing as well as awesome

  6. WEATHERDAN says:

    So it looks we do get a cooldown next weekend. But how cool and how wet. That is the $64 question. With predicted highs from the mid to upper 30,s it looks to me like maybe some sticking snow at night but at best rain and snow during the day or above 1,000 feet. Still this is a step in the right direction. If we can get some marginal low level snow event next weekend and then maybe a low level temperature inversion then some of us might see a white Christmas. Not great chances admittedly but better than most years. This situation is still over a week away so a lot of things could change but it is hopeful. We don’t have to get a major Arctic blast here to get some sticking snow. Just the right circumstances. Now we shall see what happens.

  7. The persistence of the offshore ridge (see cliff mass blog) has me wondering if, from at least a precip/snow perspective, Mark should dust off the file folder containing the fork graphics and turkey graphics, as their use may be indicated/contemplated in the not so distant future. Yes, this ridge may intermittently send a few dry breaths of arctic air our way, but its position is not conducive to snow.

  8. WEATHERDAN says:

    Latest (2:56 PM) NWS Forecast has Salem with a chance of rain and a high of 38 on Friday the 20th, interesting.

  9. Sapo says:

    GFS and ECMWF are wavering between runs of snow/non-snow. It’ll be a matter of a few degrees. They are still consistent on a decent amount of precipitation Thursday, though, so maybe we can hope for a quick snow event.

    • Ben T says:

      Days of 31 for highs and like 25 for lows would make me happy. Just as long as it snows several inches and sticks around for a while. Major Arctic Blast? Major Snowstorm? I’ll take Major Snowstorm.

    • Sapo says:

      Well we would be looking at highs about 36, this is clearly not as intense as the last arctic blast, meaning that we wouldn’t have snow sticking around for awhile.

    • Mark says:

      Looking a any number of given models, to this point, we are on a edge. The bottom line trend is that the high pressure needs to back off to about 150… It is far too eager to creep into us, instead of backing off and rising into the gulf.

  10. BoringOregon says:

    Maybe it time to Issue another *BoringWeatherAlert*…

  11. Marcustheweathernut says:

    12z gfs……. Boring……. Cold trough…… Boring!!!!

    • JohnD says:

      Cold troughs aren’t bad–right!? I would take a
      period of low hill-mountain snow levels with a
      flake or two mixed in in the lowlands. We do
      need to be working on the mountain build up.

    • Dave in South Salem (500') says:

      That’s right, 11 inches at 5,000 feet isn’t going to cut it

  12. Garron near Washington Square says:

    While I am sure we’ve had drier falls in the past, I wonder about sky cover stats for falls past. I can’t ever remember more sunny days like we’ve had from Oct. till now. Some years we’d have inversions that lasted for weeks, but we really scored for sunny days IMO this fall. That alone will make winter seem far less gloomy than usual. Only have to get through January to mid March before days get long enough, and storms become less numerous, if we go back to winter as we PNW’s know it.

    • Punxsutawney (aka HIOPHIL) at work by Sunset High elev ~280 says:

      Not much drier actually. If you don’t count September in any event, only 1976 would have a drier Oct-December than what we have seen so far in Hillsboro. That’s 84 years of records and any time you compare to 76-77, that’s not a good thing.

      And taking the 12z GFS and Euro at face value, I’d say 1978’s totals won’t be threatened in the least.

      December 2013 is on pace to be the driest in recorded history in Hillsboro. I’m assuming PDX is similar.

    • JJ78259 says:

      Compared to last year and the years previous Portland weather has been dry maybe the long awaited drought I always wished for before I moved will come true!

    • Chris s says:

      Yes, nothing like wishing for a drought. Great for the ski resorts, local mountain business, summer water supplies, and on and on. Serious fail jj.

    • JJ78259 says:

      By the way the 7 day forecast is looking another dry week with only 24″ inches at Meadows not much snow to ski on.

  13. W7ENK says:

    It snowed for the first time in over 100 years in Cairo, Egypt.


    And yet, I can’t seem to squeeze out more that a dozen snowflakes here under The Dome?! 😦

  14. gidrons says:

    At face value the Euro 00 would give me snow at my location in the hills, quite a bit of snow 18th-19th. Valley floor gets chunky rain. We’ll see…

  15. Tyler Mode in Battle Ground says:

    Waking to 41 degrees this morning. Now that’s a change!

  17. Kenny says:

    The new 00z GFS has now trended colder. -15C+ temps are seen just east of the Cascades.

  18. Mike (Orchards 255') says:

    First day of winter going to feel like winter?????

  19. Marcustheweathernut says:

    Lots of cold members!!!! we shall see:) http://www.wetterzentrale.de/pics/MT8_Portland_Oregon_USA_ens.png

  20. dothgrin says:

    32 in Aloha…I have a feeling it could be a mini ice rink in the morning. Then, Portland winter fully returns

  21. W7ENK says:

    Temperature rollercoaster this evening…

    Morning low of 22 degrees. Stayed below freezing until 2:30, just about when the rain started. Extremely light icing observed on trees in lower Milwaukie (downtown/McLoughlin), but none in upper. 33 degrees when I got home, about the same time the rain ended. Temperature rose to 35, dropped back to 33, up to 34, down to 32 now 37. Oops, that was 10 mins ago, now 38.

    No wind at all through all of it.

    I guess it’s back to the regular same ol’ same ol’ now, eh??

  22. chiefWright (Marquam) says:

    I love it. Now 48 degrees, no precip, and a dry SW wind. After being the coldest spot in the N Valley for the last week, this is a treat.

  23. boydo3 N Albany says:

    I wouldn’t give up on the rest of this winter. In fact, models are still trying to bend things around more from the north in a week or so. Plenty of winter left 🙂

  24. Ben T says:

    Pretty successful arctic blast. Extreme cold temperatures and some snow. I still think we see something bigger. Maybe not as cold, but snowier 🙂

  25. JohnD says:

    As far as the “great winter event of 2013” goes (and it WAS a GREAT event if you live in the mid-south Valley!); I was trying to think back what it was like during the rest of the winter in the roughly comparable season of 1972-73. I am pretty positive that after the Dec. ’72 event, that was IT as far as low elevation winter events go for the rest of the season. Let’s hope that is not the case this time around AND that the NORTH Valley gets included during the theoretical second event!

    • WEATHERDAN says:

      Well that isn’t quite true. In early January 1973 the weather turned cold again. Between the 4th and the 11th the highs ranged from 34-39 and the lows from 19-34. During this time Salem received about 2 inches of snow. After that the Winter was basically over. I suspect we will see some colder weather in here late next week. Not a big Arctic blast but still fairly cool. Maybe in the 37-42 degree range for highs and 27-32 for lows. Still very early in what I suspect will be a wild Winter.

  26. Heatblizzard says:

    40s now with south breezes. Jumped up from 34F to 40F! Yikes!

    If this were the 1960s I can guarantee we would be having a widespread *silver thaw* with all sorts of transportation troubles as the warmer air arrives but as it is due to less Artic Ice we just can’t have the right situations.

    Heck 2003 and 2008 provided *old fashioned* situations on transitions.

  27. Marcustheweathernut says:

    Man I sure miss these days!!!! http://youtu.be/bsieNGLKTSY

  28. Andrew (Beaverton, OR) says:

    Just got back into beaverton from hillsboro, jackson school road area is VERY icy.

    • Mark Nelsen says:

      It’s funny how the icy spot is getting smaller and smaller. 40s seeping north slowly. I’m sure it won’t get to 40 tonight in Hillsboro, but it looks like the last holdout is the Tualatin Valley at this hour.

  29. chiefWright (Marquam) says:

    Very strange. It’s in the 40’s now with a warm south breeze. 10 miles to the north, Molalla is almost 10 degrees colder.

  30. mrskrupp says:

    Forest Grove is an ice skating rink! I parked on the street
    In front of my house and fell on my a** just getting out
    Of my car!!

  31. GPeal says:

    All – Please note it is dangerously icy in Forest Grove. The neighborhood streets are completely iced over and extremely dangerous.

    • Heatblizzard says:

      Dad did relief pharmacy and used to travel to Forest Grove and the temps there have always been 5 degrees colder then other people in these marginal situations.

      I imagine the coast range mountains and the hills of West Portland act as a *bowl* for cold air to sink into making it very difficult to scour out.

  32. AlohaWeather says:

    Icy in both Hillsboro and Aloha. Plants, objects, and sidewalks coated in Ice. Side roads are shiny but not slick yet.

  33. BoringOregon says:

    Temp down to 35 out here. Any chance of Ice on the roads tonight?

  34. WEATHERDAN says:

    AFD from Seattle regarding late next week.



    • Mark says:

      Interesting, considering the EURO started this idea, and then backed off, and the GFS has followed in kind, continuing to back off the idea. 8/9 days out is quite a bit, so things can shift again, but two arctic blasts in one year? Odds are quite low…

  35. boydo3 N Albany says:

    A lot of “if casting” around here….

  36. TruckinAint4Sissies says:

    This should make tonight’s run (Spokane & back) interesting Hood River east :/

  37. Slavic S. says:

    Great cold spell except for the fact the transition event and snow decided to go and take a hike else where… Frustrating. I do for some reason think that we will have a 10 inch snow event before the winter that hasnt started yet, will be over.

  38. Heatblizzard says:

    If this were the 1960s we would be looking at a major *Silver Thaw*

  39. alohabb says:

    Soooooo close, but no cigar.

  40. Roman~Snow-Zone-Monmouth, Elv. 223' says:

    This system would have been a great little snow storm if the upper layers of the atmosphere were colder. Currently 31.5F and light rain, no wind.

  41. Paul D says:

    Is it safe to come out yet? 🙂
