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!

The eruption in the Caribbean looks like a VEI 3 (St. Helens was a VEI 5) I wouldn’t expect any affects on global weather patterns as fascinating as it may be.

Hard to say, since we can’t actually calculate VEI while the volcano is still erupting. FWIW, this is a substantially larger eruption than the one in 1979 (which was also a VEI3 and erupted for several weeks).

St. Helens also wouldn’t have major climate impacts given its latitude unless it was a VEI6 or higher. Tropical volcanoes have more profound effects on the radiation budget.

36 at my house but 32 down the road at work currently. Was hoping for a freeze at my location but oh well.

And it's still erupting in semi-regular intervals of every 2-3 hours. Pretty impressive so far.

00Z ECMWF showed a system on day 10... and the 00Z EPS hinted at the same thing.    Some rain would be quite nice by next week.     In the meantime it appears its going to be basically sunny for the next 8 or 9 days which is pretty crazy for the middle of April.

The first half of January was very warm. Unprecedented in spots.

I'm sure you felt cold though.

By next Monday I a going to be golden brown and looking like a Greek God.  Say it isn't so!  What a beautiful stretch of weather that is inbound.

If only the government would allow me to gather with family and friends and BBQ.

Anyone have Biden's cell number so I can ask permission?

Got down to 34...31 degrees about 2 miles south of here. 34 isn’t a super impressive low here this late. We got down to 34 consecutive nights here in mid April last year...and even had a low of 35 on 4/29 in April 2019. Some pretty impressive temps this morning in other locations though.

One of the things about these eruptions is that they are very short lived, maybe 30 minutes or so.  Hard to really get a lot of SO2 and ash in the stratosphere and affect global weather with such sort lived eruptions.  Mt. St. Helens big eruption lasted about 9 hours, and Pinatubo's also lasted 9 hours.

Dropped to 28 this morning which is the latest I've recorded a min this low.  SEA set a new record with a low of 34 and OLM tied their record of 27.  Nice!

We got a head start... we are already tan and now it will be easy to stay that way.   😄

Checking to see if we can get the boat de-winterized this week.   Might want to take it out next weekend.   No swimming yet... but it would be really nice to be back out on the water in warm sun.

Too bad temperatures will now be well above average the next 7-10 days.

PDX dropped to exactly average for the first 10 days of April. May go down a little more today then nowhere but up for the foreseeable future.

The initial one may have lasted longer...not sure on that.  I kind of look at this current eruption as being something that might be a balance in some cases, but not one that's going to have a huge impact on global temperature average.

Big NW to SE gradient this month.  I'm running below -2 for the month so far.  FWIW the warm weather probably won't last THAT long.  The usual suspects for cold nights probably won't have positive daily departures until well into the week either.

Not a huge gradient really.

And I’m sure this map will look a lot different in a week!

Bellingham joined the party this time with a very impressive 28 breaking the record of 31 from 1967.  Numerous records this morning.

You are only seeing the bad lately.  No way to downplay the trough that just came through and some of the other recent ones.

I think the problem is you are only seeing the “good”. This morning was very impressive. It’s too bad we couldn’t keep the cold beat going and throw some rain in the mix too.

Got down to 25 after a 56/32 spread yesterday. 

Really looking forward to the stretch of nice weather starting today!

Tonight is a no brainer for another impressive min, but Monday night is more interesting.  Pretty impressive north wind pressure gradient which we are normally sheltered from here.  Wind sheltered areas could do very well Monday night with very dry air in place.  Very continental looking for quite a stretch.

It also needs to be pointed out the pattern during week two is very delicate, and big surprises could develop with short notice.

This spring has been his jam. You’re trying desperately to fit a square peg in a round hole because it happens to have you in a foul mood due to backyarditis. Gets old. Today looks gorgeous!

The surface pressure gradients look fantastic for huge diurnal temperature spreads later this week.  The nights will stay cold in some places which will really mute any warm anomalies from the max temps in the daily averages.  For the most part the gradients are going to be mostly northly with only a limited easterly component.  North winds could inhibit max temps near temps near Puget Sound also.  Not really a torch for a lot of places when averaging the highs and lows.  Obviously places like SEA and PDX will probably have pretty mild mins as we get deeper into this though.

At any rate...big minus departures today, below normal for almost everywhere tomorrow, and then mixed for Tuesday.
