Warmest February on Record: Final Numbers

5pm Monday…

February was not only the warmest on record here in Portland, but also warmer than a typical March!  Today’s low of 45 and high of 52 are the final numbers of the month, so now we can calculate the numbers:

MarkFebruary_WarmestOnRecord

A full 5.5 degrees above average!  This JUST BARELY beats February last year for the top spot…by all of .1 degree.

These past two Februarys have been a far cry from the cool and wet February 2014 (with the snow & ice) haven’t they?

March is sure looking wet, at least the first two weeks.  Check out the GFS meteogram…the ECMWF is similar:

KPDX_2016022918_tx_240

Temperatures should be near normal, but then it turns cooler about a week from now as a cold upper-level trough edges closer.  You can also see the shift to cooler on the ECMWF monthly maps from last night.

Week 1 & Week 2 (these next two work weeks)

 

Then in week 3 & 4 the trough weakens and retreats farther west along with the ridging over us and north.  This would imply spring starts the 2nd half of the month:

For the real geeks, here are the precipitation anomaly maps for the 4 week period showing much drier weather after the 2nd week…we’ll see.

    Good heavens… pounding hail and strong west wind! (For about a minute.)

    Mark:

    karlbonner1982 robbed me of my thunder-spring started 2/1. (St. Bridgit’s Day in Ireland-the traditional start of Spring there.)

    Two hottest Febs, two hottest Octs…hottest winters/summers…perhaps it will finally end this autumn? (See Jason’s charts.)

  4. Tyler Mode in Battle Ground says:

    WOW! I’ve never had the wind pick up so quickly!

    Gusting close to 30 mph in a matter of seconds!

    33 mph now

    Temperature went from 49.5 to 52.8 in 8 minutes.

  5. Tyler Mode in Battle Ground says:

    47.5 for a mean temp at my station in Battle Ground. 2nd warmest in my 5 Februaries of record. Last year was warmer with a mean of 48 degrees.

    It was my wettest at 5.90″, edging out 5.80″ in 2014.

    This spring in February has got to stop. It’s enough to make me very grumpy. My grass is growing and the weeds are everywhere. How am I supposed to get my full winter break from yard work? Groan!

    • I sympathize: I’ve hardly even thought about sharpening the mower and I see the grass already needs a trim. Right now, however, I’m wondering how much rain I’ll see for the first week of the month.In March 1987 I recorded 4.13 inches for the first 7 days. Hopefully, I won’t have near that amount this time.

  9. Oh my Great Goddess, Mark. You just claimed that according to the maps, “spring starts the second half of March”?

    SPRING STARTED NEARLY A MONTH AGO!!!!

  10. Well, my preciptation total for December -February ended up as the 4th wettest in my books since 1975. I haven’t yet completely calculated my mean temperature for February 2016, but it won’t be the warmest on record for sure.Still, like Portland’s it was warmer than the average mean temperature for March. Furthermore, I have had 3 March months in past years that were cooler than the preceeding Februarys: 1977,1991 and 2002.

    Record cold January 2017…period! Cold snowy 2016-17 super La Niña train on its way😀👍🏼

    Again, ‘have to ask: Are we talking about the 1940+ Portland Airport demarcation point? It will forever be frustrating to me that –unlike many cities–we don’t have a singular official recording station that predates to antiquity. I get it, we don’t, so “get over it”! Still, when “all time records” are bantered about, embellishing data is appreciated. (Notwithstanding Mark’s incredible, beyond reproach dedication to this blog!)

    The charts look great to me. Get some more snow in the mountains next week for a little more skiing, then go into a drier warmer period for spring break.
    Time to plant those peas, walla wallas and potatoes!
