Here's the additional Damage Point text from the Enderlin EF-5 survey: -33 train cars derailed -19 fully loaded grain hopper cars -1 fully loaded grain car and 4 tankers pulled away -empty tanker thrown 145m -train cars thrown 2x farther than EF-5 threshold -train cars were 4x heavier than models

Thanks to @drkimwood.bsky.social for making this graphic of #Helene. What I find interesting is that it wasn't in Southern Appalachia for that long. But the predecessor rainfall event that came before Helene was the 1-2 punch that brought devastation to the area.

There are actually very few people with the title "Climate Scientist"... But there are many of us who identify as part of that community. Gotta say having my community classified as "Evil" by the head of state of my county is a first for me... A chilling first. www.nytimes.com/2025/09/23/u...

Heartbreaking. Is this really what people voted for? www.nytimes.com/2025/09/17/u...

in light of the kimmel news, just a reminder that a few days ago a prominent fox news host literally called for killing homeless people. right afterward, someone shot up a couple homeless encampments. that fox news host still has his job.

The Onion has made maybe the funniest thing we've ever done and I can't talk about it yet and it is killing me.

It would be fun to have Departments of War and Peas.

Checking in with the #Python Community. Setting up a new mac, is miniconda still whats recommended? Do you do miniconda and then install mamba?

Take a bow gentlemen. You hit the ball out of the park.

Attendees at @ametsoc.org #AMS41Radar can blame me.. I left my umbrella back in Chicago

Well @kurdzowx.bsky.social perhaps take solace that Minneapolis is beating Toronto @shobenase.bsky.social ;)

Cool work from Roger Wakimoto at @ams41radar.bsky.social looking at photography and linking it to dual pol radar data #AMS41Radar @ametsoc.org

honored.

WRRL contributions to #AMS41Radar follow in chronological-ish order! 1. @morgancrows.bsky.social P121 in Tuesday’s poster session (2:30-4:00 PM ET) entitled “Impacts of Triple-Moment Microphysics on Tornado Production in an Ensemble Simulation Framework” #AMS41Radar ams.confex.com/ams/41Radar/...

And we’re off at @ams41radar.bsky.social ! @shobenase.bsky.social kicking us off

The big radar meeting in Toronto has already started with the short course on Open Radar Science beginning today. It's going to be quite the week! Stay tuned for day-to-day details (and maybe some live-skeeting). #AMS41Radar

The Open Radar Science short course at @ametsoc.org 's @ametsoc-radar.bsky.social @ams41radar.bsky.social is underway! Maestro @mgroverwx.bsky.social conducting!

Happiness is working code. @ams41radar.bsky.social

Hello Toronto! Hello @ams41radar.bsky.social !

As people start arriving to #AMSRadar41, we want to welcome you to Toronto 🇨🇦! …and introduce you to CASKR (King City), who will be your host weather radar for the week 😄!

On our way to @ametsoc-radar.bsky.social @ams41radar.bsky.social ! I can't believe it was 8 years ago I chaired this with Scott Ellis! Thanks to @shobenase.bsky.social and team for chairing! And all the @ametsoc.org staff.

I'm calling it. It's Bike To Everywhere Week

Pushed SHARPlib 1.0.1 to conda-forge/PyPI. This bugfix addresses lack of well defined missing value behavior in find_first_[pressure,height], proper setting of missing values in lift_parcel, and fixes some issues with find_lfc_el with incomplete profile data. github.com/keltonhalber...

Checking in on oceanic warmth in the Atlantic: the tropical wave with a 70% chance of development over the next 7 days is projected to traverse warm water that was somewhat modified by Erin's passage a few days ago (dashed line on inset map). Image shows Argo float observations in the upper 120 m.

Here’s a first-of-its-kind vertical cross-section analysis of the eyewall of Category 5 Hurricane Erin, captured by AgileRadar’s ROARS radar system installed on NOAA’s Hurricane Hunters P-3 aircraft.

Reminder: Your atmosphere is a fluid.

More awesomeness coming soon to a browser near you from #SPCLabs. Also, we (SPC) are going to support this for our NWS IMETs!

Around half of Canada's wildfires are caused by lightning and other natural causes (including birds dropping fish on powerlines). These burn about 80% of the acreage. Around 15% of the U.S.'s wildfires are caused by lightning. They burn about 60% of the acreage. Some fires need to burn.

DEATH TO RAINBOW

Every reputable expert I know considers mRNA vaccine technology to be one of the most revolutionary advances in medicine in our lifetimes. Its inventors won the Nobel Prize in 2023. Shutting it down now is pointless self-harm to humanity.

Finally, some good news…

This looks like an insanely great (long-term, multi-phase)) upgrade to Grant Park chicagoyimby.com/2025/07/park...

Everyone posting complaining about changes to Stage 21 of Le Tour can shut up. The four climbs to the Basilica, messing up the normal procession is inspired. #letour

To attack a technology that is saving out planet because it ruins his view from his golf course, while par for the course (see what I did there) still continues to shock me none the less.

Let's check in and see how July temperatures have changed (trended) over the last 75 years. Not great. Part of the story out west is a concurrent decrease in precipitation creating a feedback cycle. 🔥

100% In some of my down time in Rotterdam recently I really enjoyed taking trains to Delft and to the coast near the Hauge.

I had meetings planned at the ARM User Facility site in Oklahoma Thursday. Heard the facility wanted some fresh photos so I packed my "good camera". Got up at 4:30am on Friday and very glad I did. A clearing overnight stratus deck lead to oil painting style skies. These are the times I love my job

Another day of potential flash flooding in central Illinois, especially in the red area that saw the heaviest rain yesterday

After being in the Netherlands for a week I desperately want a cargo bike..

When you use AI what do you learn. AI has a place but we must keep knowledge discovery front and center of all we do.

(1 of 2) Brilliant analogy "Cloud seeding is like a match. Trying to light a rock with it (no water vapor) is useless. And lighting a match on a blazing inferno (very moist atmosphere, like on July 4th morning over Texas Hill Country) also won't have any noticeable effect" - Prof. Tom Gill

Some big lightning over Chicago tonight! Wow!⚡️⚡️ #ILwx #Chicago #WXsky

-cough- Py-ART -cough-

Is it real? Is it not? I hate the timeline when I can’t tell if it is an onion headline or not onion headline, and when the head of the onion is talking about it being a good headline
