A New Record…Still No 65 Degree Days

11pm Tuesday…

We just set a new record today; a chilly one!

WE’VE NEVER GONE THIS FAR INTO THE SPRING SEASON WITHOUT HITTING 65 DEGREES.  The previous records were in April 1945 & 1950.  In those years (as you see below), we finally made it over 65 on the 18th of the month. We didn’t do that today so now we’re in uncharted territory for PDX and a new record has been set for latest “FIRST 65 DEGREE DAY”.  Of course those records go back about 80 years.


Check out the warmest temperature each of the last 11 Aprils in Portland:


It’s pretty typical to see 75 or even low 80s at some point during the month.  But I think that’s unlikely this year as we stay in a regime with weather systems frequently passing through the region.  Still no sign of anything more than one or two days with brief upper-level ridging.  Take a look at the 12z ECMWF 850mb ensemble forecast:


There is very good agreement through the 27th with these ensembles.  You see the spike of warm air later Friday through SaturdayAM.  But then it’s back down to near/below normal temps up around that 5,000′ elevation.  There is quite a bit of “noise” right in the last couple of days this month.  That means the different ensemble members diverge a bit, but that’s normal for 10+ days out.  This evening’s GEFS (GFS ensembles) is quite similar:


except there are quite a few warmer ensembles around the end of the month.  Even with what we consider a “cool pattern”, this month has still be pretty reasonable.  Most stations in Oregon are running at or less than 2 degrees below normal.  Here’s the USA analysis, which seems a bit cool compared to actual observations for our area:


Compare it to the first 17 days of April last year!  Wow…what a crazy warm month that was and a temperature pattern across the USA reversed from this year.


By the way…even with the “cool-ish” 10 days ahead, our daylight does keep increasing.


The sun set at 8:01pm in Portland today and will set beyond 8pm for the next 4 months.  The next “pre-8pm” sunset will be the weekend before Labor Day (August 26th).  Enjoy the long days!

    With the news about North Korea, Russia, Syria, Iran, China, and the US heating up our long range outlook to cooling down. 850mb temps -4C going into May.

    Looking forward to tomorrow; What I really want is one sunny day, from sunrise to sunset. Haven’t seen that here since the second week of February. Even Easter Sunday, as nice as it was,saw a veil of high clouds here. Gotta see that blue sky!!

  3. Jason Hougak says:

    If we are going to break records then at least we are doing it in style. Worked in Government Camp today and still have a good 4-5′ base. This cool weather is doing an amazing job keeping the snow from rapidly disappearing. I’m anxious for yard work but I’ll take this spring any time. Enjoy it everyone.

    I am so sick and tired of this grey chilly weather, so I extended my vacation a few more days. Hawaii for 15 days never sounded so good. Peace!

    Hey Mark….is this “spike” of warm air on Friday and Saturday going to be due to an East wind? Just wondering if we’re (Corbett) going to get to enjoy it, or are we just providing the warm air to the metro area while it’s 40mph ++ winds out here?

  6. Roland Derksen says:

    We could go to 65F or above here as well on Friday. The key is the wind: If I see a light NW wind develop, it’ll happen. By the way, this date(April 19th) back in 2008, was quite a different scenario: I woke up that Saturday morning to over 2 inches of snow, covering the spring blossoms!

    Sunny and 82 just a few thousand miles south!

  8. Paul D says:

    Now if Friday’s forecast drops a few degrees we can keep pushing that record out even longer!!

    So glad we’re not repeating last April – that was miserable.

      Sunny, dry and warm is miserable? Really? Many people with outdoor plans might disagree. I remember being outside for much of last April enjoying the beautiful weather and hardly found it to be a “miserable” experience.

    • Adam in SE says:

      This blog is like a meterological Bizarro World… what most normal people would consider “good” weather is cause for whining and consternation on here. (And vice versa.)

    • W7ENK says:

      FFS man, the warm weather hasn’t even hit the extended forecast range yet, and already you’re b!+c#ing?

      Honestly, I think you whine just for the sake of whining.

    Oh th other reason I want ore sun, is once I get 4 more panels.
    I got a little suprise ..

    Its called no pay for Ac Usage lol.

  10. Lee Wilson says:

    Just want some sun, because I am wondering can we lower our PUD elow 12 KwHrs.
    And to see if we can get to a Park and play.
    But I have a feeling were in a “Solar Minimum..which will be bad for tomatoes and other warm weather crops.
    But better in not having to use A/C as much.

  11. JERAT416 says:

    I’m in no hurry for heat. We have all summer for that. 70 is fine but no 90 in the beginning of May, please! I’m waiting for the 67 forecasted for Friday to drop 10 degrees like the last “pushing 70” day forecasted.
