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...

Coming from one of the original MRMS developers: Impressive!! A multi-platform MRMS browser that works well with mobile devices. Check it out!
I'd like to introduce you all to a personal project I've been working on recently. It's called Heimdall, and it's an MRMS + ProbSevere situational awareness monitor for CONUS scale severe weather. It's got roaming, alerts, archive mode, and is fully client side.

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.
