Record Lows & A Look Ahead

11pm Tuesday…

The chilly and very dry air mass gave tons of weather stations east of the Cascades record lows on Tuesday morning.  Here’s a list from the Pendleton NWS:

 *GOLDENDALE, WA          24 / 1920       22         1905

Burns was 13 degrees and Baker City was 12, both records for the date.  As you see below, Baker City hasn't seen a 12 degree temp in the 2nd half of April since the airport records began in the early 1940s!

Coming up…for those of you who think the 7 Day forecast never actually improves with time but most likely goes downhill?  Not this time; it appears Thursday and Friday we’ll see temps stay in the mid 70s.  The 00z WRF-GFS even tries to get us close to 80 on Friday…we’ll see.

So we may end up with 5 days of straight sunshine for this workweek!

Here’s the new 00z GFS ensemble chart:

You can still see the chilly showers for the weekend, but HUGE variety of solutions by the time we get to Tuesday.  Anywhere from -4 to +17 at 850mb!  There seems to be a “cold cluster” like the chilly/showery ECMWF, and a cluster showing upper level heights rising dramatically…Roll the dice…

    Low 70s here and wall-to-wall sunshine.

    While it’s been a VERY sunny spring so far here in Oregon *Sunshine hours anybody?* up in Washington has been a totally different story with many days of overcast and drizzle not going away until recently. A tale of two worlds.

    I have kept track and when it comes to troughing I place my bets on the Euro and Canadian after tracking weather models in read only mode at Western.

    They *The Euro and Canadian models* have been right especially for Washington where the GFS many times predicted widespread sunshine this spring with minimum clouds only to not be wrong but blasphemous when the *event* actually occurs while several times the Euro hinted at the GFS being wrong yet people turned a blind eye to it acting like it didn’t exist.

    Selective memory I guess?

    Only one poster regularly mentioned the Euro models but he got constantly teased for being *negative* but wounded up being right in the end many times.

      Good Lord, that’s insane! I was camping at Glass Butte this time last year, I’m so glad it wasn’t in the single digits then, though it did freeze and we had a dusting of graupel overnight our first night out.

    I’ll take the “heights rising dramatically” ensemble members for a nice Maytide heatwave!

    Oh, and “first”?
