January Stats: Warm, Wet in Places

An interesting month here in Portland.  Chilly, windy, and sunny to start, a bunch of heavy rain plus mild temps in the middle, then mild and dry for the last 3rd.  It all averaged out to a warmer than average January with near normal precipitation.  Still no snowfall either.  As of February 1st the “terrible winter” of 2010-2011 has produced no sticking snow in Portland.  Very rare for a moderate-strong La Nina winter.  Yes, the palm tree is a bit dramatic, but notice we had 14 days with highs in the 50s here in Portland, that’s unusual too.

Here are the stats for some Pacific Northwest Stations:

Station, Temperature Anomaly (from 30 year average), Total Precipitation, Precip Anomaly

Portland: 41.7 (+1.78),  4.78″ (-.34″)

Salem:  42.3 (+2.0),  3.25″ (-2.59″)

Eugene: 41.5 (+1.7),   2.05″ (-5.60″)

Olympia:  40.2 (+2.1),  7.27″ (-.27)

Astoria: 42.3 (-.1),  12.20″ (+2.58)

Redmond:  34.8 (+1.6),  .47″ (-.50)

Pendleton:  35.4 (+1.6),  1.41″ (-.04)

Here’s a nice image showing temperature anomaly across the West since the beginning of December.  Click on it for a better view.  No surprise here; the Western USA has had a very mild winter so far.  I see Burns sticks out nicely with all the cold nights and chilly days due to early snow cover on the ground that started back in late November.  So now it’s February and what do we see?  More of the same for the next 7-10 days.   Unusually dry conditions for AT LEAST another week.

Use this post to put in your stats for this past January only, please continue discussion on the previous post.

    Theres been quite a significant drop in the RSS global surface temperature. A moderate to strong El Nino followed by a strong La Nina is the cause..The southern hemisphere has dropped the most.

    Some fascinating weather has unfolded across the Northern Hemisphere over the last month… Blue also shows up across the UK where December averaged 5.2C 9.4F below normal..

    Paul Airport temperature cloudiness and wind information at hours corresponding to the old fixed-scheme times and 1961-1980 midnight to midnight absolute daily temperature maxima and minima Fisk 1984 . This reconstruction created reasonable approximations of the Pioneer era daily midnight to midnight maxima and minima and in addition to reducing biases in recalculated 1820-1872 monthly mean temperatures allowed for daily maximum minimum temperature graphs to be constructed as is done here for every year of the history.- 1820 to the present… This adjusts for the fact that individual calendar days have higher or lower inherent year-to-year variability standard deviations in daily mean temperature.

    For comparison here are my numbers for my Vancouver station.

    Just watching the weather channel and areas of cold air and snow.

    All that is happening now reminds me of the movie i saw, minus its ending…2012.

    Everything is lining up just like in the monie.

    A friend of my brother who lives in n e Washington, was looking at -14. They said their weather pattern has changed up there.

    I also compared temps in the pacific n w today…28 in sandy, 14 in tygh valley, 14 in sisters, 6 in baker city, -14 in Idaho falls, yet -6 in Montana.

    What’s going to happen in two weeks here.

  9. How do I delete my post? Sorry everyone I missed the fine (ok, bold) print!

    Oh whoops! I just read this thread is only used for January stats. My bad…..

  11. I would love the Arctic air to not only fill up the nw, but cover all 48 contiguous states so that key west and San diego barely get above freezing for a high!

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

    I just got my Computer back. Tuesday morning as I was literally backing up my files my power supply died, so I have only briefly looked at today’s 12Z runs. 12Z EURO was awful and 12Z GFS looks pretty good to decent.

  13. O.C.Paul says:

    What the..??!! January is over??? Why did’nt somebody wake me up?

  14. PaulB/Eugene says:

    Looks like normal PacNW weather returns in 10 days…G of AK trough with Cascades snow, onshore flow regime. No arctic air in Oregon…maybe in Bellingham/Everett beyond day 12.

    • PaulB/Eugene says:

      If we add up all the accumulations of hail we get in March-May…it will exceed snow accums for the winter in the Willamette Valley. Would not be surprised if this is one of the better springs we have had for cold air mass convection…lots of CBs and mammatus

  15. Tyler Mode in Battle Ground says:

    5.48″ here in Battle Ground

    Set 31 new record highs and 31 new record lows 😉

    First full month of records

    Highest: 57, 14th
    Lowest: 17.8, 1st

    Highest wind: S 22 mph, 14th
    Most Precip: 0.99″ 16th

    Lowest pressure was only 29.91″…that is very weird to me for January.

    It will be interesting to see my Vancouver station stats compared to up here.

    According to the airport:

    Averaged high 46
    Averaged low 33
    Warmest high 59
    Coldest high 30
    Warmest low 46
    Coldest low 15

    Precip 1.28 in.

    The downtown station:

    Month as a whole 39.6
    Averaged high 45.9
    Averaged low 34.0
    Warmest high 60.2
    Coldest low 17.5
    Precip 1.14 in.


    In other words, almost as warm as a normal Portland January, but about as dry as a normal January in the true low-desert areas to our east (Umatilla, Tri-Cities, etc.)

    If we stay dry much longer, early spring soil moisture will be quite scarce unless we get a good soaker in March. We’re also approaching the time of year where if the weather is relatively warm, grasses really WILL start to take off and grow strongly. The hill at the far west end of town already has a solid green look, and the other slopes are definitely showing more than they did three weeks ago (even if not everyone on this blog believes me).

    The bad news is that as grass grows, water demand grows, and soil moisture begins getting depleted if we don’t get some rain to replace it. If it stays quite dry through late winter and early spring, we could be in for a serious drought and fire season this coming summer!

    I guess they’ll do anything in Chicago to stay warm. Just saw a headline that said they were “rescuing drivers on LSD”. Read on and found that was short for Lake Shore Drive.

  20. HIO Phil (Punxsutawney) elevation 189' says:


    3.59″ rain, well below normal.

    Mean Temp 39.6 +0.0 degrees

    My station 4.12″ rainfall, well below normal.

    Mean Temp 40.1 +.6 degrees

    Two minor freezing rain events. Best description of the month would be “Bleh!”
