The CSSL/NTP assisted the US National Weather Service (NWS) with their upgrading of the official rating of the June 2025 Enderlin, ND tornado from EF3 to EF5.
Announced by the NWS today, it’s the first EF5-rated tornado in the US since 2013.

Today we have a special blog post on a new NTP tool for AI-assisted satellite review, with the method described by its developer - the NTP's Daniel Butt. The tool is being used experimentally and is already producing results. More on that shortly!

Last post for the big radar conference in #Toronto - from the 3 co-chairs. We did it! With much support from @ametsoc.org and volunteers. Thanks to co-chair Julian Brimelow, and to @shobenase.bsky.social for leading the charge. It’s been a great experience working with the both of you. #AMS41Radar

I don't usually post food photos, but this was a pretty good BLT: thick cut locally sourced bacon, toasted bread with mayo, salt and pepper, and a side of seasoned garlic cloves baked in the oven on the bacon tray.

The NHP has been busy preparing for field operations, both at home and abroad! For the #ICECHIP field campaign, the NHP and Western's UMS designed and built 4 platforms which collect and preserve hailstones, capture high-speed video of falling #hail, and measure hail fall speed with a small radar.

And there you have it. At least a dozen tornadic supercells in an STP bullseye of 9, smack dab in the center of an SPC High Risk. We can stop complaining now, or rejoice, or just appreciate the NWS.

Today: A bunch of my federal colleagues are being terminated from their jobs, and there was a misinformation attack on UCAR (which is currently hosting me on my sabbatical).
This sort of day is becoming frighteningly normal.

Permafrost thaw will cause billions of dollars of damage to Arctic infrastructure. Roads (like this roller coaster due to frost heave), buildings, runways, coastlines. Delay at our own peril.

Hey Canadian storm and weather friends - do you ever look at the FOCN product to see the forecast discussion for any significant weather day? If you do, look at this note. The MSC is considering discontinuing the issuing of this discussion. Thoughts? Email: [email protected]

Always disappointing to see #AI captures get such traction when the real thing which takes much more time/effort is seldom as rewarded.
