35 years ago today, the 11 May 1991 Cimarron County, OK tornado, about 1-1.5 miles to our west. Back in the day when we had *zero* data in the car. This image was used for a postcard that still sells today. And you can watch my video here: www.youtube.com/watch?v=iCq6...

Now that I have two chases under my belt for 2026, it's been too long since my last #tornadotuesday post. This is a few miles NW of Rogers NM on 5 June 2025, from a separate supercell and about 45 minutes before the Morton TX dust wedge.

For #TornadoTuesdsy, a rough 16x time lapse cut of my Morton, Texas, 2025-06-05 Insta360° roof camera footage, showing the genesis of the tornado and other cool 3D low-level flow structure via dust tracers in the rear-flank downdraft.

For #TornadoTuesday, here's one of my photos of the 5 June 2025 dusty wedge tornado near Morton, Texas. This was one of 4 tornadoes I observed on this storm, plus 2 more tornadoes observed on an earlier storm near Rogers, New Mexico. All on my birthday this year!

Radar images or photos? I do have more photos. As for radar slides, I found this oldie, which includes the Falcon storm:

Here's an old-timey radar image comparing the sizes of three tornadic supercells, with the Falcon storm in the middle.
