Today's thermal profile is pretty much dry adiabatic all the way up to 700mb, thanks to some descending easterlies above 5000'. We worked extra hard to reach the 60s today, despite the chilly air aloft. Side note...Unless they knicked it just after 5pm, it looks like KSEA avoided the 60F mark by a hair.

No matter what though the dry air is making it feel much cooler. And as an ode to how deeply mixed today was, despite dewpoints in the mid 20s, there were still some tufts of cumulus about this afternoon; way up high of course at the very top of the boundary layer where the particularly precocious lifted parcels nudged just barely high enough to saturate, probably around 7000'+.

I got a nice little weekend off coming up for me. Warm and breezy Friday, a bipolar Saturday with a warm morning crashing to onshore flow and drizzle by dinnertime, and a fairly cool Sunday. Might even nab one of those sub 50F highs which are rapidly becoming harder and harder to get.

The cool and wet May is looking like the real deal, Andrew. 

Big Nino to Nina flips tend to equate to stunningly beautiful Mays. 1988, 1998, 2010.

I like my Model Y. I’ve had it for 4 months. I’ve never used the Tesla charging stations so can’t comment on those. They are starting to install chargers on residential streets in Seattle attached to the power poles, those are going to be on every block eventually. 
 

Would never buy that monstrosity that is a Cybertruck. It’s too bad that Tesla is headed to the toilet after so much promise. The smaller Rivian that looks like a Subaru is going to fly off the shelves when it is released.  Hopefully BYD starts selling cars in North America soon as well.

I mean, unlike you, I don't hate America, so I hope BYD doesn't sell cars in the United States without a proper review from the WTO.

I've got a Model S, it drives great, plenty fast, and a 10% to 80% charge takes about 15 minutes at a Supercharger. Charging at home means that I rarely have to think about range, but when I have to during a road trip, I hit about 400 miles.

While I don't agree with your stance that Mao was actually a great guy or that America would be a much better nation had the Wobblies lynched Bill Boeing (again, your views, not mine), I do agree with you that the Cybertruck looks like garbage. Well, that one giant a** wiper blade, cheap interior, and carrot shaving edges. Looking forward to the company getting a new CEO one day soon.

I like the Model Y but that’s one of the reasons I’m leaning towards the Model S. It can go 405 miles on 🔋 .

Our state is jumping right into things. The Washington Department of Ecology declared a drought emergency for nearly the entire state.  They say we had a very dry winter, which we did.  They say we have low snow pack and it's diminishing fast.  “There is simply not enough water contained in mountain snow and reservoirs to prevent serious impacts for water users in the months ahead.”

According to WA Ecology, statewide snowpack stands at 68% as of Tuesday, with some areas — including the Olympic Mountains, Lower Yakima and the north Sound — registering “significantly lower.”

“Streamflows in many basins are already below 75% of normal,” Ecology wrote. “Forecasts for April through September have Chelan River streamflows at 52% of normal, while the Stehekin, Methow and Okanagan rivers are forecasted to have 59% of normal streamflows.”

Most of Washington is not in a drought. But it’s okay for them to be proactive if they think more drought conditions will come throughout the warm season.

Seems like it is mainly a North Cascades snowpack issue.

Can you imagine if we are blessed with a wet May. The ENSO forecast is coming more into focus now. Really starting to look like we land on a moderate Nina.

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.

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.

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

06Z GFS was not so emphatic about a major pattern change... looks more variable like we have been seeing lately.   

EPS also looks variable and seems to be shifting the focus more to the south with the troughing next week.   I am sure there will be some rain events over the next couple of weeks though.

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.

June 2022 was extremely wet through the first three weeks of.the month though.

For the first 20 days of June 2022 there was only one day here without rain and only 2 days at SEA with 0.00 for the day.   But for the first 10 days of the month it was a warm, humid rain.     

Then it only rained on 5 days from June 20 - October 20.

Nice spot! Gate looks breachable, however. 

I very respectful to these sorts of gates!  After all attack dogs may reside on the other side 😱

Too funny Front Ranger 🤣

34* currently and we had a low of 33* this morning in Federal Way
