Another strong tornado on 6-11-2026, this time near Dwight, IL

Not bad for having not even made the decision to chase until 6:30 pm! This tornado was north of DeMotte, IN around 8:00 pm on 11 June (0000 UTC on 12 June).

The second significant tornado we documented yesterday impacted Streator, IL. We were going through town when it roped out so I did the best I could to capture it. On the last shot I was busy taking pictures of the utility pole damage and didn't notice the new tornado lurking in the background.

Tornado striking a farm east of Dwight, #ILwx last night. And this was like...the 4th craziest tornado of the event.

This is probably tied for top chase of all time with 4/26/2024. And supremely local in areas I grew up in. Really hoping impacts were minimal.

Almost 10 minutes with 100mph gusts and about 30 minutes of severe gusts (more than 58mph).

Great day chasing the Palmer Divide today! Followed a supercell for several hours to the east. It tried hard to produce a tornado a few times, but couldn’t quite get it done. Fun chase nonetheless! #cowx

This is the tornadic portion of the storm that was near Ramah, Colorado earlier today #cowx

First time storm chasing in South Dakota way back in June 2005 I got to experience the Northern Plains meaning business with its linear storm systems this time of year. Just an enormous amount of energy released as it steamrolls a large area

I see that gerrymander 👀 #WxSky

Walked out of a graduation ceremony and that south Denver cell was overhead. Had a several minute walk back to my car - no umbrella or jacket so I just ran for it. Lots of CGs crashing and pretty sure I heard a few pings of hail hitting nearby cars😬

I accidentally drove through the damage path on my first out-of-state chase a week later. Can't overstate how much the Hallam tornado haunted my early years chasing.

A more recent EF3 tornado was also an oddball: The 2015 Berthoud tornado began approximately 3 miles south of Berthoud, then tracked to the west-northwest! www.stormdig.com/index.php?op... #WxSky

I'm always concerned about my antenna wires breaking the Faraday cage and routing a lightning strike into the cabin. OTUS guy is routing that possibility straight to his skull #WxSky

2016 y'all

now the real test is whether those automated alerts are actually timely and have correct info, since that’s often the failure point. But for pre-event messaging this is outstanding!

Tons of heavy, wet snow in the trees in south Denver pushing branches to the ground. Just had to shake the snow out of my small trees to save them #WxSky

The Supreme Court has affirmed the President's authority to dismiss any and all members of congressional designated boards - even if the enabling legislation prohibits it. The only exception is members of the Federal Reserve Board of Governors. 6 members of the Supreme Court are to blame for this.

Happy Earth Day! 🌎 To celebrate, consider streaming PBS NOVA's new "Rain Bombs" episode! You might recognize some familiar atmospheric scientists ;) I feel very fortunate to have played a small part in this episode. One of my most memorable career experiences so far!

My jaw dropped when Mike H first posted footage of this Dupree cyclic multi-vortex merry-go-round tornado-fest in 2010. South Dakota + stationary supercell = perfection. youtu.be/LitatyGimpU?... #WxSky

Inside the Wyoming, IA tornado today!

How it feels doing literally any task right now.

Dose of reality

"To the cloud" - done well - provides a rare opportunity to onboard modern infrastructure and practices that can greatly improve velocity and resilience. Hoping this will help operational infrastructure capacity especially during big weather events.

Excellent video document of a forgotten Nebraska beast, one of my favorite segments on Instability Released and (if you’re especially cultured) Extreme Instability IV. m.youtube.com/watch?v=ss82...

Here's the outlier you've all been waiting for. It's currently 75F in Denver, CO at 11 PM MDT. On March 21st.

Last night was much needed aurora therapy for me. I will never tire of seeing these magical lights

Cuba, perhaps best known for its lack of hurricanes...

June 15, 2023: As many were just going about their day, this #tornado formed and immediately began to carve an EF3 damage path through Perryton, TX. After impacting residential and downtown areas, the tornado collapsed a radio tower and exploded a fuel storage tank as I rushed to escape #WxSky

Just in: UCAR has filed a lawsuit against NSF, the Commerce Dept, NOAA, and OMB to prevent the dismantling of NCAR, alleging "violations of the Constitution and the Administrative Procedure Act."

The Morrill Fire in Nebraska has killed 1 and consumed 549,000 acres with 0% containment. This is more than 10% of the entire area burned by U.S. wildfires in 2025, and makes it one of the 20 largest fires in U.S. history. Sunday forecast is grim: High Wind Warning, 25-35 mph winds, gusting to 50.

Do NOT call the NWS during warning operations with your radar interpretation and second guessing! They have many in-house eyes on the radars and are experts in interpretation and data artifacts. You are disrupting a workflow on which lives depend. This is important 👇

Example of lightning definitely not always striking the tallest thing

AGU submitted a response to the NSF regarding the proposed restructuring of NCAR. For more than 60 years, NCAR has been a cornerstone of weather prediction, Earth system science and scientific training. We urge NSF to pursue transparent consultation and evidence-based reform. buff.ly/eDGI0Cw

Large trees down on CSU’s campus from today’s high winds #cowx

From a 0% marginal day to a confirmed #supercell #tornado — sometimes the high plains over-deliver🌪️ May 25, 2017 I caught this spinner in Yuma County, CO, on timelapse — Turretcam footage shows clear ground circulation (arrow) forming right on the inflow boundary. Full chase log link in 🧵 #WxSky

Everyone remembers Wray, but for a few the magic started in Eckley. May 7, 2016 I blasted east, betting on a #supercell cluster erupting near the state border. Just as I arrived this scene unfolded — a ghostly #tornado touching down north of Eckley, #Colorado 🌪️ Full chase log link in 🧵 #WxSky

Please clean the ice and snow off your vehicles before driving!

The US NSF has put out a "dear colleagues" letter that is essentially a yard sale list for @ncar-ucar.bsky.social It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab? If you have thoughts, send them to [email protected]

It's gonna be May 🌪️ in 71 days. Tornadoes will again be roaming the Plains. Flashback: May 17, 2019 I was chasing this monster #supercell near McCook #Nebraska. After a white-knuckle detour through a torrential rain core, I broke out just in time to intercept this EF-1 #tornado near Farnam. #WxSky

This thread shows a deliberate defunding of U.S. science, engineering, social science, innovation, and education excellence. It’s a U.S. national security, competitiveness, and economic disaster.

A personal update from veteran French storm chaser and world-class filmmaker Chris Asselin⤵️

Snow squall rolling into Laramie earlier this morning

This is fine

Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.

AMS is deeply concerned by the repeal of EPA’s 2009 Endangerment Finding, which concluded greenhouse gas emissions harm health and well-being. The science remains clear: human-caused climate change is already causing harmful impacts. Read the full statement: https://bit.ly/4tBwz9w
