That makes sense. Good use of MESH and why MESH is still a good parameter to have.

and the background environment (I know there is some stuff out there already), it could make for a very useful GR2 user defined placefile.

latent. By the time you see a signal in MESH, the hail is probably already happening. A PAR network with 60-90 second full volume scans would probably be needed to make MESH useful in real-time warnings ops. One potential avenue, is if we can find a robust relationship between radar signatures

Others have noted that MESH can often struggle in high shear environments, which might align with your note on Spring and Fall season where you likely have stronger mid and upper level flow.

MESH is a great review and research tool. Right now, with the current 88D network, its data flow is too

similar ZDR/KDP, but one produced softballs, and one only produced golf balls. Then, see if the background environments could tell the story better despite similar radar signatures.

A sounding archive similar to the tornado one may compliment this well. Particularly, understanding the CAPE below and above the freezing layer, estimate of SR flow. Then, relate that to dBz and other dual-pol observations. This can then provide context to why two storms had 70 dBz up yo 45kft and

I make a good effort to comment my code. But it is amazing that if I get side tracked for a few weeks, my return to that code I can't figure out at all what my line of thinking was.

They needed to ice the kicker, but didn't have any timeouts left. So they did this...

@stormscale.io @kentuckyweather.bsky.social Curved on the new build is great. Having the middle of the monitor unimpeded makes up for the lower amount of screen real estate. Thanks for the input again!

I did it back in February. All my HWT experiences have been good. The PAR is the one that my decisions and thought process were substantially improved.

What is the webinar experience like with respect to screen sharing? Do you share a window instead of full screen?

Any drawbacks?

I am leaning curved monitor. I like that it's less head movement, and when I roll back, I can see everything better (probably because there is no gap).

Welp, in the market again for a computer monitor setup.

Not much of a gamer. Mainly do some coding and lots of GR2 viewing.

I have been using 2, 24" monitors. Do I stick with dual monitors, or, do I go to a larger curved monitor (but overall slightly less screen real-estate).

I've had terrible luck with smoke detectors that wirelessly communicate with each other. Any time we had lightning nearby they went off, and if we ran the microwave too long they also went off (no smoke from microwave).

This is awesome to see Kelton. Thank you for your efforts on this. I see this becoming very valuable! Wish I knew more about coding to contribute.

We can already see segments developing RIJ features, and strengthening cold pools with cell mergers help to increase vertical pressure perturbation gradients. Even if not a derecho, this can still be a high impact wind MCS, bow echo, maybe LEWP?

Don't let the storm's odometer countdown to Derecho criteria get in the way recognizing the substantial wind threat this environment will support. There is a lot of moisture available, and, it's distributed in such a way to favor precip loading and strong evaporational cooling.

With just one radar, full volume scans every 60-90 seconds wasn't too bad. Having to work with multiple PARs, could potentially be a different story. But, I'd rather have that data available and find a way to adjust how we use people in warning ops. We don't have to keep 88D like processes in ops.

The thought in my head:

"Outflow boundary from morning convection has surged southward, have removed marginal risk along and north of Interstate (number) in the 1630z update".

Hopefully in the coming years that expands. I have explored some of the plug-in hybrids out there. If those prices come down that would be very feasible for me in the future.

Did you have to primarily stick to Interstate routes to ensure enough charging stations available? My main concern is for my trips westward where I don't stay on I-80 or I-70 for long.

That was the biggest pain in the [neck] mesoscale storm environment I have ever had to try and navigate. Somehow outflow boundaries formed new outflow boundaries. The big lesson: We have a long way to go in CAMs handling cold pools.

I know we have supercells in the Northern Plains, but very interesting occurrence in Nebraska. Weak showers producing 70+mph winds. Big time evaporative cooling. Boundary layer lapse rates 9.2 C/km.

Okay.

I don't know for fact, but from my experience writing PNS products for surveys, the language certainly sounds like a QRT has been activated. I am confident SMEs in and outside the agency are still actively reviewing this.

Nice write-up! I still have a few others on my to read list.

Do you know if a quick response team (QRT) was activated? I have worked three events that required one. Two of them stayed at EF-3, one did go EF-4. I think we waited 4 or 5 days before we released any EF-4 information so the QRT could throuoghly investigate.

RIJ working efficiently to 1.) Increase strength of bookend vortex and 2.) Align the leading edge favorable for more robust meso vortex generation. A lot of available vorticity north of Interstate 94.

Quite the day in North Dakota. Two discrete supercells eastward, with ranging bowing MCS across the middle.

All tornado warnings regardless of tags and language activate WEA.

Flash Flood Warnings have to be considerable or catastrophic tagged. And Severe Thunderstorms have to be destructive tagged.
