2012: 4th Wettest Year In Portland

This one probably doesn’t surprise you…are you sitting down???  It’s been VERY wet the past 2 months (actually a bit longer).  The October-December rain total is around 22″ here in Portland, that’s way above average as you can see:

MarkFall_Rain_Record

In fact you have to go back to the first few days of October to find a dry spell longer than 3 days.  That was the end of the driest 3 month period ever recorded in Portland!  What a change…

The wet end to 2012 and the wet spring have pushed us to the 4th wettest calendar year ever here in Portland.  Observations at the Portland Airport go back to 1940:

MarkRain_RecordPortland

Notice that we are nowhere close to the record wet year 1996.  That year we had flooding in February, November, and then again in late December (after a pair of damaging ice storms here in Portland).

It’s extremely unlikely we’ll get the 1/2″ to push our total to #3, so it’ll remain our 4th wettest year since 1940.  We don’t combine rain totals from PDX with those downtown because it’s a wetter location.  Those records go back to the late 1880s in several locations downtown.

Where do we go from here?  MUCH DRIER.  Not totally dry, but every little rain through the next week.  In general over the next week we either have upper-level ridging over us or weak systems splitting as they approach.  Yes, the dreaded SPLIT-FLOW.  For us weather geeks, this means SEVERE BOREDOM.  No stormy weather, no snow, ice, extreme cold/warmth etc…

No sign of an early January arctic blast either on any model.  Wayne Garcia asked again today if he needs to put on the studded tires; and again I said “don’t bother”.  This may be one of those winters where the lowest elevations don’t get snow, or it may be one of those where we get a severe arctic blast and snowstorm the last week of January…who knows.

    There’s a faint but noticeable 44° halo around the moon.

    Similar to this:

    Rumor has it, that’s a sign of snow.

  2. Ben T says:

    The dew point is 32 degrees now in Longview with small bands of precipitation moving in. Hmm?

    My peak wind was just 4 mph today. My lowest since December 17, 2011

    • Click the year the table on the right for comparison.

    • flurball says:

      if you can hold or gain a bit from where it was it is an improvement versus the y to y trend. look at the diff say 1997. with temps in Alaska so far this year I would think this might be a year we don’t lose traction for the first time in many. just my opinion

    • flurball says:

      November report on sea ice. graphs show its in line with last year so nothing lost but well below 20 year history. like relestate it’s location…location

      Arctic sea ice expanded rapidly during November, at a rate of 98,600 square km (38,100 square miles) per day which is faster than average for the month. By the end of the month, the central Arctic Ocean had completely refrozen and the Bering Sea had above-average sea ice coverage. The Barents and Kara seas were much slower to freeze, both of which continued to be mostly ice free by the end of November. Below-average ice cover was observed for Baffin and Hudson Bays.

  4. What’s this? YES! Even more 00z WRF analysis
    Yep, as a few of us have been mentioning, the cold pool is definitely trending stronger and colder. Tonight’s run shows a strong cold pool now with 925mb temps of -9c to -11c over the lower Columbia Basin, Tri-Cities area.
    10:00 AM January 1st

    This is far stronger than previous runs and will deliver a heck of a fake cold regime into the Gorge and PDX metro.

  5. ====================================
    8:37 PM Update
    Unnecessary Analysis Summary for no particular reason

    It is quite chilly out here near Gresham.
    Current Conditions
    Temp: 34.5
    Dewpoint: 23
    Wind: E @ 22.3
    I did NOT expect it to be this cold with gusty east winds and mostly cloudy skies. It literally seems like with the increase in winds it’s is if anything pulling in colder air already from the cold pool in the eastern Gorge and Columbia Basin.

    I glanced at IR Loop earlier(Damn, was it ever exciting, alright, not really), but noticed the weak 1014mb low off the Washington Coast appearing to sag southeast.
    Today’s 12z MM5-NAM
    7:00 PM Friday

    This sure handled this wrong showing it moving northeast over Vancouver Island into southwest British Columbia. WRONG.

    WRF-GFS also was similar, but equally wrong.
    10:00 PM Friday

    • Another problem is it shows the PDX-DLS was only supposed to be at -2mb, when it is actually now at -4.7mb and appears to be increasing. Also, the 925mb cold pool currently looks a bit colder than modeled, especially over the low Columbia Basin around Pendleton where WRF implies a narrow bubble of warmer 0c temps were to be. They are not.
      http://www.spc.noaa.gov/exper/mesoanalysis/s11/925mb/925mb_sf.gif?1356754683401
      12z models also showed we lose the east wind late morning Saturday, but I don’t believe that occurs now.

      Now, check IR Loop
      http://www.atmos.washington.edu/~ovens/wxloop.cgi?ir4km_enhanced+12
      There’s the weak low drifting S-SE offshore. This certainly isn’t going to track into Vancouver Island, or north across Washington either. If anything, I believe this will keep dropping S-SE well south of PDX. This should have no bearing on the cold pool over the Columbia Basin and we may not see the offshore gradient decrease as models showed for a brief time.

      Now onto 00z models tonight…. I assume they are playing catch up
      Nope, still initialized poorly. MM5-NAM again is off with the low.
      10:00 PM Friday

      Suggests the low is supposed to be west of the NW Tip of Washington, when it is already due west of Hoquiam drifting S-SE. Oops. Discard.

      WRF-GFS. Ah, finally initialized correctly.
      10:00 PM

      Closer, but the low is slightly south of this point.

      What’s my point to all of this? No idea. It just seems the cold pool is running colder than modeled and we may not lose the east wind. Temps may trend downwards too, especially east of I-205.

    I was over at a neighbors house and found that all of his rose bushes have starts coming up!

  10. As of 7pm it’s 35.2 in NW Gresham. Dew point of 29 and wind east at 8 mph.
    Looks like points east of PDX are cooling much quicker as east wind has really dropped DP’s… Interested to see if the rate of cooling, (approx 1.5 degrees per hour) continues in my area. Assuming it does, should be around the freezing mark by 10-11 pm

      I’m having a hard time following this one, it’s not broken out quite right, and WordPress isn’t helping by stripping the formatting.

      Is that low 28 tonight, high 36 tomorrow?

  12. cgavic says:

    I would like to see another winter like 1968.

  13. cgavic says:

    Now, since we have a split flow over us, the east end of the gorge and its foothills will stay white, while the normal climatic areas outside the gorge will cool off with that cool air that will drop down from eastern Washington state into northwest Oregon and western Washington state.

    The big question is, when the next system comes in……cool temps already in place.

    My New Years wish is that a very cold air mass with abundant moisture with it, will take us back where some of us got 4 feet of snow. But I’d settle for a foot.

  14. WhiteEagle - Garden Home / SW Portland says:

    Mark earlier alluded to the miniscule chance of a “San Diego Winter” here in Portland, where temps never get below freezing. My family lives in the SF Bay Area; in Santa Rosa.

    So far the “freeze score” is:
    Santa Rosa: 7
    Garden Home/SW Portland: 2
    PDX: 0

    But…the snow score is:
    Garden Home: 0.5″
    Santa Rosa: 0
    PDX: ???

    Oh, and they are beating us in rainfall as well; Santa Rosa has had 11.66 inches of rain so far this month. Christmas Day felt very Portland like there, with steady rain and highs in the mid 40s. Of course I got the obligatory jokes of “how nice of you to bring your weather with you!” Grrr…

    • I went to the East Bay ( Martinez) to enjoy some nicer weather & yikes…monsoon season there???

    • WhiteEagle - Garden Home / SW Portland says:

      Cherie, the 2 weeks around Xmas and New Years’ are notorious down there for getting hammered with heavy rain. They just haven’t quite had it recently. Last year I was in Santa Cruz and it was 77 on New Years Day! Sorry you picked a bad year! 😦

      I was hoping for the same thing and didn’t quite get my “California Break” from winter I was hoping for…oh well. C’est la vie…

    • Lurkyloo says:

      I lived in Forest Knolls for a while and worked for 10 years in Novato. There were some cold, frosty mornings out that way. Never did see snow. I just remember Santa Rosa as being HOT in summertime.

  15. SST anomalies in the N Pacific show resurgence of negative phase PDO picture with expanding cold pool Gulf AK. Latest PDO index figure not out yet, but you get the picture
    http://www.ncdc.noaa.gov/teleconnections/enso/indicators/sea-temp-anom.php?begmonth=1&begday=1&begyear=2012&endmonth=12&endday=19&endyear=2012&submitted=Animate+Selection
    Whether we get some real lowland winter weather or not is anybodies guess. But you better believe with negative end of neutral ENSO and resurgent cold PDO this will likely be an active, wet, cool late winter/spring/junuary/julyuary. Question is, will the upper level low parade start soon enough to bring snow down to the deck at PDX? Tis the only question. Forget May flowers. Ain’t happenin.

    • Marcus says:

      Nice looks like late winter again:)

    • W7ENK says:

      I fully expect a continued and further shift of our typical seasonal norms again this spring/summer/fall. We will probably see a sudden switch to consistently below normal temperatures near or at the beginning of March, cold and wet pushing all the way until mid-August or even the first week of September, and then a stretch of warm/dry anomaly lasting until Hallowe’en. Wet returns at the end of October/early November, but warm stays again until the first week of March, when the whole cycle shifts back by yet another week and starts all over again. I’ll bet if I put dates on all these marks, I’d get each one within 5 days, either side.

    • W7ENK says:

      Oops, that hit the mod filter, and in looking back for a reason why, I see I accidentally left the F out of the second instance of “shifts”. Feel free to correct that and push it on through, Mark. 😳

    • First it’s poo then it’s shi*s! The whole world is going to crap! 🙂

    • W7ENK says:

      HAHAHA!!! 😆

      Mark, you didn’t make it family friendly!!!

  16. WEATHERDAN says:

    Weather summary for the winter of 1992-1993. October was fairly normal our first freeze in Salem was on the 14th when the temperature dipped to 31 degrees. Even after that temperatures remained in the sixties and seventies until the end of the month. It was 75 degrees on the 23rd of the month. While most of October was fairly dry 2.19 inches of rain fell the last 3 days. During November highs were mainly in the 40,s and 50,s. The coldest high was 38 on the 29th and the coldest low was 25 on the 24th.The highest wind gust for November was 48MPH. On December 5th the temperature dipped to 19 degrees and stayed in the 30,s for highs.Late in the evening on the 6th it started to snow. Salem received 3 inches. Another minor snow event on the 16th and 17th gave Sale about 1 inch of snow. On New Years Eve Salem got a heavy dumping of snow that added up to 5 inches. The minimum for the month was 19 degrees. There were 10 days during the month with maximums of 39 or less. Twice we had wind gusts as high as 41 MPH. January saw measurable snowfall on 8 days. There was snow on the ground 17 of the 31 days. The Minimum for the month was 13 degrees. The maximum was 63 degrees. There were 22 frosts that month. 14 days had highs of 39 or less. In February the first half was sunny and mild. The maximum on the 7th was 63 degrees. The second half of the month was much colder and snowier than the first half. An arctic frontal passage on the 15th dropped the dewpoint to -3 degrees. During the 18th-21st Salem saw a total of 11.9 inches of snow. Spotty snow lingered on the ground in shady areas until Early March. The low for the month of February was 20 degrees. There were 15 frosts. 4 days had highs in the 30,s. The spring of 1993 was fairly normal in both temperature and precipitation. June and July were unusually cool and wet. With lots of thunderstorms. During a strong thunderstorm in early June a flash flood occurred in South Salem with a 10 foot wall of water coursing through some streets. August through October were normally warm.

    • W7ENK says:

      Nice synopsis! Your own notes, or is that info available somewhere online?

      And all that being the case, we already have a TON of catching up to do!!

  17. Ben T says:

    If I’m right in predicting that we will get an Arctic Blast starting either January 3rd or January 10th with 3-6 inches of Snow in the PNW will each of you give me .25 cents to my Paypal account haha!?

  18. 12z ECMWF
    Rinse/Repeat. If desired results are not met repeat as necessary. If split flow lasts longer than 7 days consult your physician or mental health specialist.

    • I remember in ’93 we had a lot of splitting and also a lot of snow on the ground at the 400′ level and above. Small systems with wrap around moisture. It gave the TV mets real fits. Tons of snow in central Oregon that winter. If this pattern stays in place very long, at least we can hope for a scenario like that.

    • chris s says:

      Ya I seem to remember it being pretty much the same time frame as we are in now as well. Seems down here in Salem, we saw snow at least in the air of and on for 3 straight weeks end of dec 92′ thru first couple weeks of Jan 93′. We can hope for that kind of action out of this!!! 🙂

    • marcus says:

      I believe between the 10th and 20th of jan there will be a arctic air invasion!:)

    • W7ENK says:

      1993 was a weird year. I think it was New Years 1992-1993, we had 13 inches of snow on the ground and it was bitter cold? Then during Spring 1993 Portland had so many thunderstorm days it was ridiculous. A tree outside my Junior High art class took a strike and exploded, blowing out the windows in the back of the class room, luckily AFTER our teacher had moved the entire class into the hallway because of the wind and frequent CLOSE lightning strikes. I remember it being really hot and sunny that day, before the storm moved in.

      I also remember the final episode of Cheers in May 1993 getting preempted by a tornado warning with three funnel clouds spotted over Portland. And if I’m not mistaken, 1993 was also the year the Airshow had to be put on hold for a bit because it started raining, then a funnel cloud started lowering down behind the airfield. I specifically remember the announcer saying “Ladies and Gentleman, if you’ve never seen a funnel cloud, there appears to be one hanging across the field, we’re gonna keep a close eye on it…” followed by a bit of panic in the audience.

      I think Spring 1993 was also the year I called Jim Little at KOIN to report a wall cloud down toward Oregon City visible from my back yard. At first I don’t think he believed me, but while we were on the phone he swung the KOIN Tower cam around and said something to the affect “Well look at that, that really does look like a wall cloud!” And a short bit later there was a funnel (I don’t remember if it touched down) over Molalla.

      What else happened in 1993?

    • boydo3 N Albany says:

      I don’t remember bitter cold but I remember having trouble getting to a couple job sites in the hills around here due
      to snow covered roads. And yup, lots of May t storms.

    • chris s says:

      Ya Erik, I was at that airshow that day with my dad, and the funnel cloud was off to the east a bit, but everybody around us was commenting on it, and no longer paying attention to the airshow. Strange weather year, thats for sure!! 🙂

    • Melisa says:

      I remember 1993 pretty well because I was pregnant with my first child. I remember being driven to the airport in snow and freezing temperatures in February for a trip to Hawaii. I remember crazy thunder/windstorms in late spring in which it rained so hard that all the drains backed up and there was lots of water in my basement in SE Portland. I remember a very cool, cloudy early summer (for which I was very grateful) but also that the sun peeked out on the afternoon of July 23rd just after my son was born. And let’s not forget the earthquake that March–strongest one I’ve ever been in.

      Ben: if you can get us the snow (preferably on a weekday when I’ll get a paid snow day) I will happily PayPal you a whole dollar. This has been the most boring winter ever~!

    • W7ENK says:

      Oh yeah, I forgot about the “Spring Break Quake”. March 25th, 1993 at ~5:30 in the morning, M5.7 at Scotts Mills, shaking lasted 45 seconds at my house! That was the first earthquake I’d ever (consciously) felt, and it sure was a doozie! Not in any way connected to the weather, but it certainly adds to the weirdness of that year.

    • W7ENK says:

      And @chris, what’s really strange is, I can’t seem to find reference to that Airshow funnel cloud anywhere, at all, anywhere! Sure, 1993 was right about the advent of the public InterFacePlusTubes, but you’d think there’d be SOME reference, SOMEwhere, but I can’t seem to find it. I know it happened, I saw it with my own eyes!

    • Chris s says:

      Erik, I know it happened too,I have pictures of the funnel cloud. I need to go through my pics, scan it and post it on here.

    • I found articles in the Oregonian archives about the May 1993 t-storms. Wed. May 19th 1993 stands out for me because I was at Johnson Creek Park here in PDX when the storm hit.
      This is what NWS employee Paul Tolleson had to say about it.. “Wednesday’s whopper, which sprinted through the state knocking down trees and blowing things around, was a fairly rare event. He also said that this much thunderstorm activity also is rare”.

    • Since the above link won’t work without an account here’s a screenshot of the article.

    • W7ENK says:

      Wow, thanks Mike! It truly was a remarkable springtime.

      And Chris, please do dig out those pictures, that would be awesome! 😀

    • Sandi (Wilsonville) says:

      I remember a tornado near Newberg in ’93. I think it killed some cows and damaged a barn. I also remember watching it snow while in labor with my first child in Jan ’93. 🙂

  19. I haven’t even bothered to pick up the hose that I have down to my livestock trough. I’ve had plenty of freezes and a total of 10″ of snow this month, but meaningful cold has been lacking. I will probably do it this weekend as the coming dry weather should produce a string of hard freezes at my 1600′ frost hollow.

  20. East wind increasing notably now to 20mph.
    TTD-DLS -4.5mb

    Just viewed NCEP 12z GFS and the entire run looks splitty with sparse moisture as systems fall apart inside 128 W. High pressure reigns supreme and east wind may last for 7-10+ days.

  21. David B. says:

    I can live with a split pattern for a while. Will be a nice break from all the rain, rain, rain. Hopefully it’s not all fog, fog, fog and we get some clear foggy nights and sunny crisp days out of it.

    For a while. Then my forecast late January arctic blast comes in. 🙂

  22. Longview - 400 ft says:

    Usually by the first of November, I have my water hoses in storage and water nozzles covered. Also, I have had several times had it on the “to do list” but no motivation to carry out those normally important details this winter. Which is very odd for me not to do.
    Anyone else experiencing the same mental non-urgency?

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

      Yeah, the same for me.

      Usually right around Halloween I start thinking about it. For the last ten years the average first freeze for me/Hillsboro is around October 24th, and while I have had several overnight temps at or below freezing, the lowest overnight temp has been 30-31 which isn’t low enough, long enough to freeze any thing attached to the house.

      Heck it hasn’t been cold enough to freeze the peppers, much less the hoses/outside water lines.

    • ocpaul says:

      Not gonna do it. Besides, might have to water the daffodils that trying to come up.

    • Mark Nelsen says:

      For the first time this year I blew out the drip irrigation hoses and other water pipes outside way back in early November. Wanted to get it all done instead of procrastinating…this is the year I could have waited of course!

    • W7ENK says:

      Mark, this year you likely needn’t do it at all. I haven’t done anything with my hoses yet, and I don’t really expect I’ll have to.

    • Mark Nelsen says:

      Actually this next week will be well frozen up there. Highs at 1,000′ in the western Gorge will only be 32-36. Today Biddle Butte at 1400′ didn’t even get above freezing!

    Once again, a clear evening gave way to clouds rolling in, obscuring the full moon and holding the overnight temperature well above freezing. 38.8F for a low.

    What a bizarre year for weather all the way around… again!

  24. My guess is somewhere between the 18th and 22nd, and another chance after February 3rd.

      PaulB did say the 11th. I’ll be eyeballing that date!

    • David B. says:

      For cold/snow? Really makes my 14-day 10th-to-24th window look pathetically broad. We shall see. One thing I am *not* willing to do is to proclaim this winter over at this point in time.

    • W7ENK says:

      Yeah… I tried that about this time last year, and failed miserably. Reverse psychology doesn’t work, either. 😦

      There is a fair chance of a freeze in PDX within the next 5 days…assuming that the east winds don’t kick up too strong.

      I think GFS MOS is probably in correct (too cold)…check out the EUG predicted temps off of 12Z:

      Jan 11 for arctic air may be a bit early..by a week. Euro long range has colder regime back in west Canada by 3rd week of Jan, perhaps extending S in PacNW.

      If you believe in sudden stratospheric warming events leading to cold weather (somewhere in mid latitudes)…GFS and Euro have been advertising a strong SSW event starting a week from now, which could lead to a very cold period 2-3 weeks from that point (3-4 weeks from now)…

      I must admit, I am kind of liking this weather pattern…gives me a chance to sort of unplug from the computer a bit and enjoy the weather out there (easy to say when it is 10F outside your door in central oregon)…freezeless period for PDX will be history at some point soon I think…arctic air won’t happen until at least 2-3 weeks from now…

      Oooh, those temperatures are WAAAAY too low!

      25/33 Monday?
      23/36 Tuesday??
      25/37 Wednesday???

      Not a chance in Hell.

      Add 6 to lows and add 4 to highs, then maybe.

      31/37 Monday
      29/40 Tuesday
      31/41 Wednesday

      I’ll keep track, here.
