Wonder if the lack of water in our environment could be leading to less temperature regulation?

You'd be better off asking a 4th grader if they prefer the literary works of Dostoevsky to Nabokov.

[Jesse]

Most of next work week could be in the 70s down here per the 12Z GFS.

 

This run does eventually show a pattern change out beyond day 10, but the ensembles disagree and keep us on the warm and dry side through day 17.

Yeah, that could be a possibility since we're made up mostly of water. Probably due to some negative feedback loop.

[TacomaWaWx]

0.06” of rain for April up this way.

0.00” for the month here...no measurable rainfall since 3/30.

[TacomaWaWx]

Up to 54 here at 11:30am. Should easily be the warmest day so far this year.

That can't be great for native plants.

[Jesse]

PDX running +8 compared to yesterday at this time. Upper 70s are not out of the question there.

12Z EPS...

At least it's good yard work weather. 

 

Just need a good affordable weed burner.

[TacomaWaWx]

62 degrees here at 3:30pm. Fantastic day yet again.

68 here.

Some hints at the ridge breaking down toward day 10 on the EPS.

[TigerWoodsLibido]

We use our grill occasionally all winter.

I remember having to use the grill for many days during the Dec 2008 event with 2 ft of snow and an inch of ice in the middle, leaving the power out for days (I lived in Yamhill County at the time). Best winter weather event of my life.

Like how you moved this post to the new page.

 

FWIW... still looks ridgy in the 10-15 day period...

 

[Jesse]

18z also hints that this ridge may indeed break down at some point.

Early summer vacation for your kids this year!

[Frontal Snowsquall]

Beautiful day! Hope everyone had a chance to get outside and enjoy the sunshine. Hit 77 out here in TTD.

How about that rain tho.

Smells like summer outside, air is really dry. It was dark with a temperature of 61 and a dewpoint of 38 at 8pm.

[Jesse]

Why did we stop having weather.

[VancouverIslandSouth]

Had a high of 63F here, warmest day since last September.

[BLI snowman]

Gonna be a pretty crazy setup to our east this weekend. Major storm.

Definitely an impressive late season shot of cold and snow for the northern Rockies. I’m just salty that we are entering yet another long out of season dry spell in an era that’s been peppered with them.

Big severe weather potential as well.

 

This rain shutoff is coming earlier than the last few years. Probably bodes well for a more active late spring this year.

[TT-SEA]

00Z EPS looks about the same as previous runs... but it does show a break down in the ridge and more zonal flow developing at the end of the run on days 14 and 15.

I’ve thought the same thing a few times. I guess we’ll see. Part of me also would not be surprised if things stayed mostly dry for the warm season from this point forward.
