Monday PM Freezing Rain Update

3:30pm Monday…

Welcome to the world’s slowest thaw!  Ice doesn’t melt quickly at 32-35 degrees.  Temperatures are a few degrees above freezing this afternoon in the metro area.  Freeways/highways are fine, and main roads WEST of I-205 seem to be wet as well in the lowlands.  Still tons of ice left on roads in the higher hills (West Hills) and closer to the Gorge where temps have been colder too.

THIS EVENING

  • Showers develop again and it’ll be showery through tomorrow morning’s commute.  TEMPERATURES REMAIN AT OR ABOVE FREEZING.  THEY WILL DIP TO OR SLIGHTLY BELOW FREEZING IN TROUTDALE/GRESHAM/CAMAS WASHOUGAL AREAS (NEAR THE GORGE) AND UP AROUND 1,000′ IN THE WEST HILLS.
  • Roads will remain wet all for most of us and icy roads will continue to SLOWLY melt during the night.  There won’t be any sort of “refreezing” in the lower elevations overnight.
  • Near the Gorge and the top of the West Hills, roads will remain icy with those cooler temps.  There will be additional icing of trees/power lines east of I-205, but probably not enough to cause problems.

Keep in mind that to get “new ice” on roads tonight, temperatures generally need to be down to 30.  That’s why I’m not real excited about any refreezing.

TUESDAY:  A few showers, then mainly dry.  A few sunbreaks too…  Slightly warmer so thawing continues even near the Gorge.  High near 38.

IN THE GORGE:  Continued freezing rain showers through Wednesday…mainly icy roads will remain through Wednesday morning.

    Side streets are bad in parts of Vancouver! 29° currently. Hopefully it warms and thaws before kids go off to school.

  2. Garron (1/3 of a mile from Hillsboro airport) says:

    Just a heads up. Black ice is forming in Hillsborrrro. It may be temporary and actually warm up before sunrise, but better to be safe than fall on your arse in the morning. Parking lots from Hils/airport to streets of Tanasbourne are ice covered and slick, sides of main road are getting sparkly.

  3. Dave in South Salem (500') says:

    Uh so we dropped to 31 and moderate rain has been falling for a half hour. That wasn’t supposed to happen as I’m sure I live far from the gorge and I know places between me and the gorge are not this cold. But it is happening. Strange things afoot.

    • Dave in South Salem (500') says:

      And that’s a direct contradiction of the forecast above as I definitely see ice where a few hours ago was wet. It seems odd to have a freeze/thaw/freeze of freezing rain over a 36 hour period in the middle of the valley. Especially since it stayed foggy the whole day and evening.

  4. 225' Tigard says:

    Street refrozen and sparkly here… Moisture on the way per the radar…

    • 225' Tigard says:

      Maybe due to the clear sky that just opened up above me here?

    • Boydo3 N. Albany says:

      Pretty heavy band of rain just moved thru this area. Sitting at 32 but not adding to the ice. Like to get rid of this stuff. Not a fan of freezing rain. It has no redeeming qualities!

  5. W7ENK says:

    Raise your hand if you got a series of power bumps this evening that spanned about an hour. 10 or 12 in total, accompanied by bright green flashes off to the NNE of Milwaukie, followed about 10 seconds later by loud booms. Several areas without power now, and it seemed to be spreading. Looks like it’s stopped now… for now… ??

    Bumps reported seen from Oregon City to Vancouver, NW, SW and SE Portland, Skyline, Sellwood and Gresham. Power out on lower Mt. Scott, the entire length of SE Flavel, Lents, Brentwood-Darlington, and much of Battle Ground.

    No idea what was going on, I’ll try to find out tomorrow. I’m not sure if there are any BPA lines near the large storage warehouse that’s on fire at SE 92nd and Flavel? If something bumps a major transmission line, it could be seen all across the grid like that…

    • Aleta-West Gresham says:

      Interesting! My hand is raised! My battery back up once again came in handy since one of those was enough to trigger it.

    • Holly in Eastmoreland says:

      Had same power bumps here in Eastmoreland and heard the pops. Lanterns and candles are ready just in case.

    • Boring Oregon says:

      I also had piwer bumps.

    • Steven James says:

      My hand is raised–downwards. All quiet here in Beaverton, for now.

    • Diana says:

      Yes, at top of Mt Scott, power flickered 5-6 times but didn’t go out like it did on Sunday, we had no power for several hours on Sunday.

  6. Andy says:

    Currently 31 here in Jefferson, OR. Everything is frozen outside, could be interesting if we get any moisture tonight.

  7. Tyler Mode in Battle Ground says:

    Down to 32.7. At the rate I’m falling (0.1 degree every 2.5 hours) I’ll be down to 32 even at 10 AM tomorrow.

  8. boninepaul says:

    32ºF here in North Portland. Side streets are icy again. Can this be over now?

  9. Sapo says:

    Some Portland Metro school districts have a 2 hour delay tomorrow (Portland, Gresham-Barlow, David Douglas, Centennial)…most of those are further east Portland. Still some ice on the roads in Tigard and a lot of ice on other objects and sidewalk

  10. Hubby has to drive from Forest Grove to Vancouver tomorrow morning. How are the roads looking tonight.

    • John Liu says:

      Freeways and most surface roads are okay. Little strips of slushy ice on the centerline, etc, but merely wet in the lanes. Side streets that aren’t much traveled still have some icy slush, but still okay as long as it’s not a significant hill.

  11. JohnD says:

    33′ here in inner SWPDX. Appreciable thaw today but still scenic remnants of yesterday’s event abound! Roads fine!

    Will go with Mark’s rendition that there should be no problems tomorrow.

    WILL be following any anomalies upstream. It does appear that a variety of possibilities are apparent–amid our current “El Nino” season. E.g. Early next week–more goods!? Of course, “wishing” for more events!

    • Sapo says:

      I hope we get some more winter weather lol! GFS keeps some east winds sticking around especially next week with chilly surface temps and warm upper air temps (basically the “fake cold” we’ve been having). Looks pretty dry long-term though.

  12. Anonymous says:

    Hope we get some more! if you aren’t prepared to be home for days, thats your own fault. be prepared people 🙂

  13. umpire says:

    Side roads in NE Portland still have a lot of ice on them. Temps at my house maxed out at 34.6, already down to 33. Sandy Blvd. has a lot of slush between lanes. Also still a fair amount of ice on trees and shrubs. If we get even a brief bit of rain tonight, seems like zr is a possibility. Wonder if the schools will do a 2 hour delay.

  14. Tyler Mode in Battle Ground says:

    32.8 here in BG. No ice left on most roads. Snow remains in the grass etc.

  15. Sapo says:

    Some roads are starting to get sparkly…about 34 here at my house in Tigard but doesn’t look like the temperature is dropping…Roads are just really cold.

  16. Ann says:

    Whew! That’s enough winter for me.

  17. Longview 400 ft says:

    Currently 32.9 – The high was 34.2 and foggy all day. A true midwinter day, and loving it. Go Hawks!!!

  18. Diana says:

    I’m at 1000′ on Mt Scott, temp is only 32.2. There is very little thawing. Even the tree limbs are still completely encased in ice. The wind is blowing making the limbs hit against each other, it’s a cool tinkling sound. Have not tried to get out of here today.

    • Chuck on Mt Scott says:

      I walked to Idleman and it was fine, but the side roads out of my hood were iced over still.

    • runrain says:

      Going over Scouters Mountain is fine as well. In fact, the east and south side are almost devoid of snow.

      Back from the southland, getting reaclimated. From the air, I noticed all the fog pockets in the south end of the valley. Also, not much snow south of Oregon City.

    • Diana says:

      My road is right up from the 4 way stop at Mt Scott Blvd. the house faces toward SE Pdx, overlooking 122nd & Powell area. We are almost always the last to thaw. It’s a very steep road with not very many houses, so cars don’t clear it. No mail and no garbage pick up today. I don’t mind being stuck when everyone else is, but once I know the rest of the city is back to normal I get cabin fever!

    First?

    I want school Mark! Sounds like it’s a ways off in Corbett!

    First?

    • MamaReen says:

      I thought I was, but it looks like you are…It would have been the first time for me to be first 🙂
