This week's tornado vs the 1925 Tri-State


Hey Reader,

I wrote a lengthy post about this week's "Quad-State Tornado" that struck parts of Arkansas, Tennessee, Missouri, and Kentucky. It's about an 8-minute read and worth your time if this sort of thing interests you like it does me: https://justinharter.com/1925s-tri-state-tornado-vs-2021s-quad-state-tornado/

When I started writing my book about the 1925 Tri-State Tornado, the meteorology was fascinating to me. But more fascinating was our response to it and how people encountered and endoured the storm and its aftermath. For one thing, it was unusualy warm that morning—about 50-60º in most places—and after the tornado passed over it was cold enough it started snowing. Something people had to suffer through by lighting fires inside overturned train cars.

This week's Quad-State tornado killed 90 people, whereast the Tri-State killed 695. Part of that is from better warnings and building standards, but 90 people is still significant.

Our response today is much different, and even how we rate tornados is contentious. For one thing, we rate tornados by how much damage they do to modern building standards. Something many rural places may not have a lot of.

I wrote about it here and made a few comparisons between these storms and notes on how climate change may be shifting tornado alley further east.

The official record is always going to be somewhat unclear. The 1925 event was hard to measure, there was no radar, and the NWS conservatively calls it at 219 miles. The Quad-State tornado, if it didn't leave the ground about 80 miles in as radar indicates it may have, could be 8 miles longer at 227 miles. Wind speeds, funnel speed, and other measures will take longer to establish.

Either way, the 1925 event was dramatic and terrifying and deadly. And the 2021 event was equally terrifying—at night no less—and tragic. Both will enter the record books for different things and alter how we think about and measure tornados.

Hey — It's raining and windy today with a threat of storms in much of the southern US. Every time I see a forecast calling for tornadoes or unusually warm weather, I think about my Tri-State Tornado. The kinds of stories I keep discovering from that event are nothing like the storms that pass through today. The scale and scope of the disaster is just different when you're armed with the technical know-how and expertise to manage the event. But in 1925, things just hit different. Here's an...

Hey 👋 It’s been a while since I’ve shared a big email. There was a news story the other day about a slow-down in scientific breakthroughs since the mid 1940s. There are probably reasons for why that is, or why that seems that way (not being able to randomly conduct experiments on prisoners and the mentally ill probably factors in somewhere). Back in 1882 U.S. Army Sergeant John P. Finley was tasked with a mighty big ask: “Figure out what causes tornadoes and how to forecast them.” Armed with...

Today around 1pm EST, 97 years ago, the most extreme tornado ever touched down in Missouri and wouldn't stop until it reached just north of Evansville, Indiana. I've been working on a book about the event and compiled some new notes to mark the occasion today : https://justinharter.com/the-great-american-tornado-struck-97-years-ago-today/ The whole thing is just fascinating to me and the stories I keep finding are nothing short of astonishing. I learned the other day a farmer in Southern...
