For everywhere wondering/speculating about where I have been, I am very flattered We have been on a road trip to Grand Teton and Yellowstone this week. Took a nice week off before starting a new

Getting married tomorrow so that’s why I’ve not been around a ton of late. Looks like we are about 68F out there and are ready for some much-needed rainfall overnight.

Well I haven't been around in a while. Been a little, erm, preoccupied. Hope everyone's enjoying the sunshine and warmth lately! I'll be in Arizona for the weekend, and hopeful I don't melt!

Looks like some rain showers are developing over the central sound. Probably will get our first measurable rainfall since 3/28 soon.

The relationship between our warming climate and Sierra snowfall is pretty obvious in this chart. With the way the 2020's have started I wouldn't be surprised if we end up in the 275" range for the newest 10 year period.

No doubt the widening of the Northern Pacific Hadley Cell (whatever the cause) has led to a profound warming and drying in the SW US. Hopefully it stalls or reverses soon, otherwise we could be looking at a “mega-drought” regime, similar to what happened back in 1100-1300AD.

North American boreholes reveal a distinct layer of soot deposited from fires in that timeframe, unlike anything observed in the surrounding 4000-4500 years. It manifests as far east as the Mississippi in the US, and in Canada as far east as Quebec.

12z GEFS pulled back too, as did the EPS. But next week’s warm-up is also trending into something more abbreviated on both GEFS and EPS.

Today’s 12z GEFS actually never brings 850mb temperatures above average west of the cascades through D13.

That would be surprising to me, but it’s also been the theme this spring for cool patterns to stick around longer than modeled at-range, so who knows.

You’re going to resurrect some EPS maps at this rate.

Up to 48...DP is 32. Suns trying to come out here in Tacoma so maybe we won’t get any rain today afterall. If the euro verifies the first 1/2 of April will be pretty dry with less than 1/2” of rain.

Might be kind of like last year where we entered a wetter overall pattern from late April through mid June this year. We will see...Phil was talking about us entering a drier overall period soon if so could be a dry spring in a La Niña year which I wasn’t expecting.

Starting to look like a repeat of the first half of last April. Maybe a little warmer and drier.

Yeah. For all of Jim's manic posting about how incredible and old school this spring has been, the best analog so far has been 2020. Though last spring was a bit colder and wetter than this one has been to this point.

I liked warm season 2020 except for that horrible July. I think 38/40 days were 90+ degrees in that stretch. 🤮

High of 56 this fine Easter Sunday. Partly to mostly cloudy skies most of the day, with plenty of sunbreaks. NW winds have really picked up in the last few hours, gusts 25-30mph. DP is down to an impressive 23 with clearing skies.

Current temp is 53.

Was out practicing driving (parking, so I got out of and into the car a lot) and the NW winds certainly kicked up over the last hour. 

Kinda feels like a marine push, even though this is a cold front and not a real warm season marine push, which I think are caused by pressure gradients. When the evening northwesterlies start up, open all the north and south facing windows and let the breeze flow through the house. Always feels awesome.

All winds are caused by pressure gradients.

He probably meant synoptic scale gradients vs mesoscale gradients caused by differential heating.

0z GFS and ensemble are going colder again.  Can't wait to see how this all plays out.  At any rate another heavy frost for many places tonight.

I really liked how gusty the north winds got here today.  Normally this area is pretty blocked from that direction.

I've never touched it, but I will admit I've been kind of wound up the last couple of days.  Just something I really like about this pattern.  All of the cold fronts dropping in from the NW, and clear nights with cold 850s and low dps.  Good stuff.
