Beautiful morning in the Blue Mountains of eastern Oregon. It was 12F when I took these pics around 8:30am. Gotta get our winter fix somehow.

First snow of the year! Melting quick but at least a little left. Was down south picking up a new family member.

Major shift on the 12z EPS to lower heights over the West with rising heights in the SE compared to the 00z last night. Looking like a really fun mid month on through the Holidays. Perfect timing IMO!

Steady rain started around 10 and have picked up 0.01" so far. Temp down to 38. I think the system is having trouble in this dry airmass. 

It isn't as wet as I thought it would be. Started wet and then weened off.

Not putting to much stock into things rn. Come start-mid January and there is nothing, then I’ll be nervous.

I can definitely get rain in December. So don't get very strong winter feelings until January.

Thanks for posting the EPS maps. Well, unfortunately this looks quite a bit like the wet/mild CMCE to me. What will it look like in 2-3 days though. I dunno.

There is actually noticeably more mountain snow in this run than the 12Z run (including "In My Backyard"), so not sure how warm it is.  Yeah, too warm for the western lowlands, which is what most people here care about.   Looked a little cooler in about the day 9-12 range, then about the same after that (as the 12Z)

EPS has a more zonal look to it tonight for the week leading up to Christmas. The GOA/Aleutian ridging that had been shown on the ECMWF weeklies starting a little after the 18th has not yet materialized on the ensemble suite.

Still plenty of time to go though. 

Cant remember, but on the Weeklies, did the time before the 18th also look zonal?  Wondering if the progression on the EPS today is similar to the Weeklies.

I'll take it. Thanks for your analysis.

things are looking interesting at day 10 on the GFS.  Lots of blocking trying to set up.

There we go again! Day ten and the Garbage Forecasting System. I'd bet my bank on the Euro instead of wish casting. :) The amount of 10 day'ers we should've had a LOT more cold then we have had.

      April 2024 Weather in the PNW

      It actually says more about how old I am, Jesse (22). Unfortunatley I can't share your memories of being serenaded with blessings in May 1998! edit: my main point was about green grass those two years were pretty green through mid July here, 2022 especially. Definitely not the norm of the last decade or so

      Polite Politics

      Ugh, The View. What a bunch of squawkers! He stood his ground and made Sunny Hostin look like an idiot. I have never heard of Coleman, but I completely agree with his argument. It's quite simple: By focusing on class rather than race, you are essentially still tending to the needs of the historically discriminated communities without all the justifiable blowback of race based policy. I do not know why that is so hard for some to understand. Focusing on commonality rather than differences yields a better society. But, you know what comes next... Those at the top do not want us working together. A divided nation is an easily led nation.

      April 2024 Weather in the PNW

      The fact that those are the two analogs you remember most readily for that sort of thing says more about the sad state of our climate than it does anything. 2019 actually had a top tier warm and dry May and an averagish June followed by a reasonable if not mild summer. 2022 had a coolish and wettish May followed by an averagish June, after which we descended directly into summer hellfire and didn’t look back until November. They’re getting pretty ancient now, but a couple better examples of a classic cool and wet May/June would be 2010 and 2012.

      I really hope May and June are a soaker. That usually keeps things lush into the early Summer. Already starting to see some brown in the backyard. Running out of time to save it before our wet season is used up. Nothing is worse than entering ASO browntown three months ahead of schedule and staying that way. The majority of 2014-18 were tinder dry and sickly colored. Hoping we go the route of 2019, or especially 2022.

      It was absolutely stellar. Taking out the trash at work was a treat.
