Moonlight illuminates Typhoon Halong while the infrared band reveals the inner structure of the storm, captured yesterday by NOAA-20.

While I’m at the UCAR Member’s meeting, I’m reminding everyone of the internships, workshops, and other student opportunities that they have available! www.ucar.edu/exhibit/stud...

“It is wrong to call this a compact, because there’s nothing mutual about it... It is a one-sided coercive proposition that has a bow of commonality stuck onto it that it doesn’t deserve. We need to call this what it is, which is an attempt to extort universities."

The CSSL/NTP assisted the US National Weather Service (NWS) with their upgrading of the official rating of the June 2025 Enderlin, ND tornado from EF3 to EF5.

Announced by the NWS today, it’s the first EF5-rated tornado in the US since 2013.

Excited to announce that my method for estimating wind speeds based on lofted debris in tornadoes was used as contextual evidence for upgrading the Enderlin, ND tornado to an EF5!

Read the entire statement about the EF5 upgrade (linked below). EF5s are, by definition, rare and extraordinary events requiring extraordinary evidence and extra scrutiny.

Science doesn’t always operate on social media-friendly time scales. It’s better to have the rating be accurate than fast.

It should be noted that there certainly have been tornadoes in the past ~12 years (since the previous "most recent" EF5) that had 3 s, 10 m winds well in excess of 200 mph. However, there just haven't been damage indicators to capture those (largely because few DIs can 'hold out' to >200 mph).

I've created a Bluesky Starter Pack called 'Canadian Severe Storms Community'. Makes it easy to find and follow severe storm forecasters, researchers, chasers and enthusiasts in Canada!

The struggle is real. Bro / incel culture does not help things.

Keep your cool for the young women in the room that are looking to you as a role model.

A government shutdown stalls science, threaten jobs and weaken U.S. leadership. Call Congress today and tell them to to prevent RIFs, and work together to support science and end a government shutdown.

One trick I use to quiet down a room:

Me: If you can hear me, clap once!
Nearby students: 👏
Me: If you can hear me, clap twice!
More students: 👏 👏
Me: If you can hear me, clap three times!
All: 👏 👏 👏
Repeat as many times as needed.

Students are quickly conditioned to quiet down.

“The cover had a woman, young woman with green background of the forest, following chimpanzees. And I thought, wow. She kind of looks like me. That's when I decided I wanted to do that kind of work.” - Dr. Lynne Isbell

Representation matters.

Melanie Metz is one of the most famous storm chasers in the world. We traveled around North Dakota with her to learn why she loves to capture extreme weather.

South Dakota Public Broadcasting says there's an ironic result to President Trump's successful attack on public media: It will have to rely more on NPR programs.

These two couldn't get any cuter 🥰

Saffir and Simpson are 100% bonded and will be adopted together as soon as I find them the right home ☺️

CORN-ADO CHASING! It was another hot, sunny day with record heat in the Midwest, ripe for dust devils. During the harvest season when cornbelt dust devils fill with corn stalks, I call them corn-adoes! Got my drone into a few of them today.

I remember “The Enemy Within”. S1E5. A transporter accident splits Kirk into Good Kirk and Evil Kirk. Evil Kirk gets drunk and tries to rape a female yeoman. Good Kirk flounders around and can’t make any substantive decisions.

In short, it’s an apt metaphor for our current federal government.

The Univ. of Nebraska’s Dept. of Earth and Atmospheric Sciences has established a webpage soliciting the community’s help in saving their program. Their hearing in front of campus admin is next Friday, Oct 10th. Please consider sharing why they’re essential!

Under any other administration……….

At least we now have in writing that NWS operations will continue in the event of a shutdown. I mean, I was 99% sure that was the case - but in this day and age, I did want to see it confirmed.

Look at all those bird rings. #inwx
