Light at the End of the Cold Weather Tunnel?

There are hints of a pattern change starting the middle of next week.  I see the GFS, ECMWF, and GEM ensembles from the 12z runs all show higher heights and a disappearance of the cold East Pacific upper level trough.  This would at least bring temperatures up to average.  The GFS would give us temps near 70 next Wednesday and into the 70s next Thursday!  We’ll see what happens, but even in the coldest springs we DO get periods of warmer weather inbetween the consistently chilly weather.  Remember in 2008 we had a historic mid-May heatwave…surrounded on both sides by unusually cool weather.  Between now and then (the next 6 days) cool and wet weather will continue.

I’ll be off on vacation now through the end of next week.  The next post PROBABLY won’t be until April 4th, unless some exciting weather event appears on the horizon.

I had a change of heart at the last minute.  Some of you asked if I could allow discussion to continue here…so I’ll leave the comments on.  If your comment gets moderated (for whatever reason), it might be several days before it gets approved.  I’ll check in only occasionally.

    Official high for the DLS airport today was 53. Surprising as to how much sun we got, but for most of the day, the wind was horrible.

    As of 7:30pm it was already down to 45 at the airport, and the past couple hours the wind has eased off a lot. And there are very few clouds. If it stays mostly clear with little wind, the second half of the night will be downright cold, because we have the chilly overhead temps to support it. I bet we get down to at least 34 or 35 by morning, and 30-32 is within reach. Hard to believe that just over 24 hours ago we were in the 70s with almost no wind!

    I know this is a bit late, but an 8th floor room at St V hospital with a lovely view around 12:45 today, there was a rain/snow mix that turned to hail and back to just rain. The snow was surprising. I don’t know the elevation.

  3. Josh (Gresham) says:

    Sunny and… raining? 47.4

  4. bgb41 says:

    18Z GFS..Rain 15/16 days on this run and zero 60+ days. More records that we all don’t want may fall this April.

    • Kyle From Silverton says:

      Actually this is drier and warmer then the last run.

    • cap - Hood River says:

      I know i’m in the minority, but the cold storms are pretty cool.. today was the snowiest day at the mountain I’ve seen all season long, and it’s April. Pretty amazing.

    • Karl Bonner says:

      Seven consecutive days where they never make it to 50….average of all the forecast highs is 46.7….twice the normal precip for the entire month of April in only the next 16 days. Suuuuure.

      Back during winter, at least the silly temps were confined to the bottom half of the 16-day chart. But now the insanity has crept up to the 5-day mark, and the first four days are bordering on insanity (a 48 degree high, or even 46, isn’t out of the question, but getting several such days in a row is.

      Oh well, at least it’s good for a laugh.

    • Jesse-Orchards says:

      Speak for yourself, Brian, I like seeing cold records fall. I know of a lot of people on here who do, in fact. 😀

    • bgb41 says:

      Well looks like you are the only one right now. Its April and 95% of us would like a few nice day.

    • Jesse-Orchards says:

      Cap made a comment about liking cold storms too. I was up on the mountain today as well and I agree, it was incredible up there. Government Camp got about a foot over the course of the day, and the snow was sticking all the way down to Welches on the drive home.

      We just had a few nice days anyway – Thursday and Friday. Today had plenty of sun as well. I think you just like to complain.

  5. Cgavic sandy Oregon 1,100 ft says:

    We’ve had sun, snow, hail, snow hail. In that order. Hi 39

  6. Kyle From Silverton says:

    Any decent chances to ride the 50 cent albino donkey ride today?

  7. cherie in vernonia says:

    Any chance for T-storms?

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      1-2% chance at best. Most you’ll see is a few brief hail/heavy rain showers throughout the afternoon. Maybe if someone is lucky there may be one or two claps heard.

  8. Josh (Gresham) says:

    Up to 48.1, was 40.7 45 minutes ago

  9. Mike (Orchards 255') says:

    Nice little hail shower here despite the radar not looking too impressive…

    Cold upstairs however…-5°C at 850mb and -32°C at 500mb currently..

  10. Rob "Wrath" S.E. Portland says:

    Nothing too crazy, but here are 2 pics I took of my back yard with the dusting of hail.

  11. Rob "Wrath" S.E. Portland says:

    Very impressive squall just hit here. Winds 35mph and pea sized hail.

  12. Timmy - scappoose says:

    Just had hail to rain/snow! At 400′ elevation

  13. Garron near Washington Square says:

    Guess I picked the wrong month to start growing cactus and Avacodo trees in the Willamette Valley!

  14. Timmy_Supercell (Klamath Falls @ 4200') says:

    With this kind of satellite imagery, weather changes FAST and forecasts become fudged up.

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      Although Mark always nails it pretty good, I’m he’ll make an A++ on today.

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      Darn whats with the typos?

      “I’m sure he’ll make an A++ on today.”

    • Josh (Gresham) says:

      Yay! Popcorn! haha. Alot of instability, love it

  15. Kyle From Silverton says:

    What do you call it when April is colder then January?

  16. Garron near Washington Square says:

    A light hail type shower moving through.

    • Garron near Washington Square says:

      Shower is bout over, and the heat is back on, good! Been nearly 3 days since I last used the heater.

  17. We just had a rain/snow shower. This is nuts. Where’s SPRING?

  18. Rob "Wrath" S.E. Portland says:

    Showers are starting to intensify as weak instability begins to develop. Look for heavier showers possibly hail from now until around 1 PM and a chance of some thunder from 1 – 6 PM. Convective temp of 50 is reachable and lapse rates are quite steep. As always sun breaks will be key if we are to see stronger activity.

  19. cherie in vernonia says:

    now bright blue sky & sunshine 🙂
    must be Spring

  20. cherie in vernonia says:

    Squall? came thru….very gusty winds & chunky rain…temp still 40

  21. cherie in vernonia says:

    sun break & 40 here

  22. bgb41 says:

    06Z GFS – Looks like record cold and record rains on this latest run. Not good!

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      Could be another run coming from La La Land… Very extremely rarely would there be a high of 37F anywhere in April.

    • Jesse-Orchards says:

      Places in the mountains and the east side can see highs in the 30s in April. Unheard of in the Western Lowlands, though.

    • bgb41 says:

      Obviously these numbers are not legit for KTTD. The screaming message though is no change to the pattern we saw in March.

  23. Cgavic sandy Oregon 1,100 ft says:

    Snowing hard and a trace. Temp. 34 degs.

    • Garron near Washington Square says:

      Could’ve sworn I saw splat in the rain around 8 AM in Beavertown today, at least I wasn’t imagining it, thanks Cgavic.

  24. Cherie in Vernonia says:

    Am I right that it is showers for today rather than one huge green blob?

  25. Cgavic sandy Oregon 1,100 ft says:

    Guess what? We got snow!!

  26. Cgavic sandy Oregon 1,100 ft says:

    Spring! Lasted one day. Winter’s last hurrah…pt 2!

    I’ll say this…if it’s going to get cold, then let’s get a couple of inches

    We have to put up with this through may.

  27. Cherie in Vernonia says:

    Mt St Helens cam is covered with snow 🙂 24 & dumping snow at Govt Camp

  28. After last year’s wet and cool spring, it’s hard to realize it wasn’t nearly as bad as this one so far!

    Last March at my Vancouver station featured 8 days at or above 60

    Precip was 3.04″, which is below normal.

    The temp for the month actually averaged almost a degree above normal.

    • James NE Portland says:

      But I recall that the heavy rain and cold was mostly April and May last year, March was still El Niño-ish. I would not stand for another late spring like last year!

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      And August had its own April Fools, thunderstorms kept developing but never made as far as Portland!

    • Garron near Washington Square says:

      As I remember last spring was great through most of April, then May/June brought back winter like temps and rainfall. Hopefully we are just going to get this now and not Junuary.

    March 2011 summary for The Dalles:

    Warmest – 64F on Mar 30 & 31
    Coldest – 27F on 3/3
    Avd. High – 54F, 3 below norms
    Avd. Low – 36F, 1 below norms
    Precip – 1.61″, or about 134% of average

    # of days with measurable rain/snow: 15
    # of days with frost: 5
    # of days 60 or warmer: 3

    So it really wasn’t dramatically cold or wet here, definitely on the cool and damp side but nothing to get excited about.

    Too bad – if the weather is going to be unpleasant, I’d at least like to get some interesting numbers out of it. But I’m not sure how much cold is realistic. In April 2008, despite the latest snow shower ever, very few really warm days and plenty of bitterly cold ones, Eugene ended up only 3F below historical norms for the month as a whole.

    Hottest day of the spring so far in Southern California. Here is a list of the hottest stations today. 106 degrees in Buttercup in the Mohave Desert was the hottest spot.

    • Boydo3 500' North Albany says:

      Hottest day here too. I got to 70.5. OK, so not so hot but really nice. Then the rains came back…..

  32. MasterNate says:

    SO could someone please post the difference in mean average and actual March 2011 mean temp? Very interested how much below normal we actually were.

    • HIO Phil (Punxsutawney) elevation 189' says:

      Means
      Not all that cold really. Due to all the cloud cover at night mostly as daytime highs were much cooler for the most part.

      PDX – 46.1, -1.1

      HIO – 44.6, -2.1

      SLE – 47.0, +.5

      AST – 45.1, -.9

    • bgb41 says:

      Heres a graphic you can look at Nate comparing March 2011 at PDX to normals.

    • Ya, the mean can be kind of deciving as you can have somewhat extreme variations in highs/lows but the man can be closer to normal.

      My average high: 51.6, 3.7 degrees below average
      My average low: 38.6, 1.2 degrees ABOVE average
      That leaves my mean: 45.1, 1.3 degrees below average

    • MasterNate says:

      Thanks all for the info. I guess the daytime highs were much cooler but the lows were higher which balanced every thing out, somewhat.
