Hello, Friend. Hope your weekend is off to a good start.
August brought some incredible storms, including the stunning tornadoes near Mound City, South Dakota, on the 28th. The storm’s structure was amazing, making me rethink the need to get too close. Honestly, keeping a distance seems smarter now, though I didn’t always feel that way.
OVer a decade ago, I loved the thrill of getting up close—sometimes too close. One chase nearly ended in disaster, filled with mistakes I only fully understood years late.
INSIDE A FUJIWHARA TORNADO
On April 13, 2012, an aggressive storm chase maneuver I made nearly went wrong. We drove north through a high-precipitation supercell near Cooperton, OK, and encountered a low-visibility tornado.
It has taken me 11 years to post this.

Happy August, Friend! Hope it's been a good one so far.
It's fitting that just as the severe weather slowed down, Twisters was released. Naturally, I saw it opening weekend—and it was great!

TWISTERS: 10 THINGS THE MOVIE GOT RIGHT
The movie is the sequel to the 1996 cult classic Twister. Since its release on July 19th, it has already grossed over $170 million at the box office. Because of its popularity, I thought it would be fun to review the movie from a chaser's perspective.
WARNING: SPOILERS AHEAD!
Here are 10 things I believe the movie nailed:
July 2024
Hello, Friend! Hope you're enjoying the weekend.
After an amazing severe weather season, we're finally enjoying some quiet in the Plains. So there's no better time to look back at one of the most intense tornadoes of the year!
GREENFIELD TORNADO MAX WINDS
Recently, the Center for Severe Weather Research confirmed that the EF4 Greenfield, Iowa tornado had some of the most intense winds ever observed. Based on Doppler on Wheels (DOWs) data, they estimate that the tornado contained winds of 309-318 mph!
As the 2024 #BEST field season ends, a glimpse into the data collection during the Greenfield, IA tornado. Peak wind speeds as high as 309-318 mph were calculated in a narrow region 100-160 feet ARL. These are among the highest wind speeds ever determined using DOW data. https://t.co/CM09J3VSOB pic.twitter.com/fuxfdyoi9d

June 2024
Happy June! I hope your May was as good as mine.
I just returned from a highly successful storm chase vacation. Amazingly, we tracked 9 tornadoes in just three days. And most of those came from the amazing Windthorst, Texas tornadic storm on May 25th. It had one of the best combinations of tornado and supercell structure that I've ever witnessed:
And, as amazing as that storm was, there were even more stunning storms before we arrived. And arguably, the most violent of these was the wedge tornado that hit Greenfield, Iowa on May 21st.
GREENFIELD, IOWA EF4
This storm truly was one for the ages. In progress for nearly an hour, this intense tornado hit the small town of Greenfield near the end of its path. The Doppler on Wheels, which were collecting data during the tornado, measured winds of at least 250 mph in the funnel:
Very prelim analysis of DOW data show
>250 mph peak winds, possibly high as...
This has been an absolutely crazy week or so, hasn't it? And it looks like we're just getting started!

THE YEAR OF THE TORNADO
Over the last several months, meteorologists had been suggesting that 2024 would be a big tornado year. A lot was made of the impact of high sea-surface temperatures in the Western Gulf of Mexico and the transition from El Nino to La Nina.
But as March rolled into April, below normal tornado activity continued. Several big events occurred, but photogenic tornadoes were few and far between.
One exception was a local outbreak of tornadoes that struck Iowa on April 16th. Paul Spomer caught this amazing, sinuous tornado just north of the surface...
Introduction
Welcome to my new blog. Periodically, I will be posting about weather events I find interesting. I'll also be adding chaser-relevant bits I learn from science articles. Hope you enjoy!
Basic Meteorology for Storm Chasers
I recorded a new version of the beginner's meteorology presentation I gave at NSCS. In it, I cover:
You can find it on Youtube here.
And if you find it useful, please like and subscribe! I'll be posting more content like this soon.
Storm Mergers
Also, I've been reading quite a bit of research on storm mergers and their relationship to tornadogenesis. It turns out that mergers matter -- a lot.
Did you know that 50% of tornadoes form within a few minutes of a merger? This is not an accident. It turns that mergers are important because they increase stretching.
(Y'all remember the ice skater analogy, right? Spin...
