Hi guys, I hope everyone is doing well. Wanted to share with you all my first published paper, out this month in AMS Journal of Climate. I looked at 30 years of lightning data for the western US and a

Not really relevant-- but looks like I'm going to have to stick around on this part of the board for a while....I officially committed to University of Oregon as a BA major and psych minor

It was a very pretty afternoon in the eastern Columbia Gorge. First drive out there in a few months.

That’s some shitbox ATF thinking right there. Drop and give me 50.

Well that’s pretty much all he said. ;)

 

Which is fine by me. I’m down with some ridges as long as we get some cooler and wetter periods in between.

Always been a fan of Tiger. His personal issues in the late 2000s still make me laugh and yet I genuinely feel bad for the guy for going through it. Him winning the Masters last year was one of my favorite sports moments ever.

Fan of him too, best golfer of all time. You could say his libido has helped him on the field but got him in trouble off of it .

Wow, high temps actually underachieved by a couple degrees today. Good note to start the month on!

00z NAM looking a little more favorable for something to pop late morning, shows some pretty strong convection along the front. Good dynamics with the unusually strong low, would be great if we had a little more warm air and surface based instability to work with ahead of it.

Quarantine brain and a few sleep poor nights due to work has made today feel more like April 31st than May 1st.

Good day tomorrow to lay in bed and enjoy the soaking!

Hope I can break my not seeing a lightning bolt streak that stretches all the way back to...December.

 

Yup.

It's pouring here....none of the models even advertised showers at this time. Maybe I'm just trying to put meaning where there isn't any but I feel that the atmosphere is certainly energized in advance of the front tomorrow...could see some fun gusty winds and strong downpours.

We call that “crapvection” out here. Overturns and stabilizes the atmosphere before the best forcing arrives.

 

Though I guess that comparison only applies in a highly CAPE dependent situation.

That image reminds me of the March 2011 squall line. That one did stretch all the way down to Eureka, CA and it all formed over the waters in the late AM. It held together for hours and triggered marine warnings.

FWIW... the 12Z GEFS is much less aggressive than the operational run with breaking down the ridge through day 10 at least.

Zilch here with mostly sunny skies. Radar and satellite show all the action staying to the northwest. NWS point forecast says 100% POPs with categorical "rain" until 11 a.m. (less than an hour from now), but it's dry as a bone.

12Z GEFS holds the warm west and cold east pattern right through day 16.   

 

Here is the 10-day mean from day 6-16:

And here is the end of the run... the pattern changes very little.
