PNS statements and DAT suggest tornado count for 12/28-29 to be ~80 tornadoes, with 6 EF2+ tornadoes. Another event to be a lesson that downcasting a QLCS tornado risk is a good way to end up looking silly and conveys a wrong message.

Terrible news for the field of atmospheric sciences, I hope this isn't long term but any freeze on science is completely unacceptable. If not mistaken I think this will possibly include some mobile radar projects or could in the future.

Only in the United States can you have the lowest of expectations and anticipate the worst yet still be impressed by just how bad things actually do get. Shameful and dark days on the horizon, we must still stand up even when our darkest hours loom.

I have completed a 3km WRF simulation of the 18Z NAM from 12Z March 4th, 2025 to 06Z March 5th, 2025, here are the results. The relative region of this sim is from East Texas into Alabama, and from TN/MS border south to the coast line.

I did another WRF sim of March 4th, 2025, using the 21Z RAP, and at a grid of 2km. Here are the results of the sim, which goes from 12Z-2220Z and starts in east TX and ends into the MS river area.

Today in history 🗓 18 March 1925: The great "Tri-State Tornado," the deadliest tornado in U.S. history, traveled 219 miles from east central Missouri to southern Indiana during the afternoon, claiming over 695 lives.

Four intense supercells from my WRF sim of the March 14th, 2025 tornado outbreak. This is a 1000m sim based on the 3/14 17Z HRRR, and its clear just how potent the environment really was based on the results.

Ever wondered what an inflow sounding looks like with an intense supercell in a WRF sim? Well here is an inflow sample of the Grandin, MO supercell in my 3/14/2025 WRF sim.

One of the very interesting things I've learned today is that my 3/14/25 sim had an intense tornadic supercell pass along almost the same path and time as the Des Arc EF3 tornado. Also a 03Z modified profile from Lodi, MO in the sim versus RAP f0 sounding from Cape Girardeau, MO.

Automated convective outlook using SPC threat levels for 02 May 06Z - 03 May 06Z (24h), using #thundeR machine learning models. Storm season in Europe is slowly spinning-up ⛈️ #wxtwitter

Aerial views today from Tanner, AL and Killingsworth Cove Rd. Alabama, where several intense tornadoes touched down yesterday evening. Several areas of mass treefall and cycloidal markings are present amongst the damaged areas
