What an absolutely unreal year 2024 has been.

At 9:28 PM CST (03:28z) on December 10, 2021, Mayfield, Kentucky was taking a direct hit from a near high-end EF4 tornado. The downtown district was completely destroyed, as well as the Mayfield Consumer Products candle factory. Twenty-two lives were lost in and around the city.

4 years ago tonight I witnessed a violent tornado cross I-55 outside Hayti, MO. Stopped to administer aid to impacted truckers and on a gut instinct grabbed an HPD Officer and searched a field 100 yds east to find a flatted semi and badly injured driver, Ali, clinging to life. We

December 10-11, 2021: The worst December outbreak in US history impacted the Midwest and Mid-South. 24 of the 71 confirmed twisters were significant (EF2+). Several dominant multi-state supercells were responsible for intense tornado families. 92 people were killed. #wxhistory

December 9-10, 2023: An outbreak of 17 tornadoes struck the Southeast US. Five tornadoes in Tennessee & Kentucky were significant. Clarksville, TN, was struck by an intense EF3, and in the Nashville metro, an EF2 tore through Hendersonville. Seven people were killed. #wxhistory

On this day two years ago, a deadly and significant tornado outbreak struck the Nashville, TN metro. While most models did poorly handling the event, this 22z ACARS sounding shows just how crucial 0-1km focused SRH and 3CAPE can be in sig. cold season outbreaks. #wxtwitter

These were also modified to the observed storm motions for context.

Two VWPs of the infamous April 27, 2011 Tuscaloosa-Birmingham, Alabama EF4 tornado. It's incredible to see the environment these storms were dealing with. ~700 m2/s2 0-3km SRH, ~500 m2/s2 0-1km SRH, and a largely streamwise environment is how you get EF4+ tornadoes. #wxtwitter

Southern Mississippi got quite unlucky in April 2020, with one EF3 and three EF4s impacting the area. Here is a satellite image displaying all four paths.

Me, two years ago: - smart and capable - doing cool science - a source of lawful good Me, today: here's every sounding for every tornado that has ever happened since 2003

Four HREF 500mb setups of the largest tornado outbreak sequences from this year. Three of these days produced at least one violent (EF4+) tornado. #wxtwitter 1. March 14th (MDT) 2. March 15th (HIGH) 3. April 2nd (HIGH) 4. May 16th (MDT)

2011 FAV: SUPER OUTBREAK! APRIL 27th. What a crazy and unfortunate day for the good people of the southeast. We caught several tornadoes this day. We were sitting in position for the Philadelphia, MS EF5 when a guy in front of us ran off the road into a tree. We HAD to stop and

fun fact this is a RAP sounding that exists. 1 hour after 2018's (likely violent) Capitol, MT EF3

Satellite imagery from the April 12, 2020 Chattanooga, TN EF3 tornado. It’s difficult to discern RFD and outer tornado damage, but the zone of apparent convergent damage spans at least 1.6 miles in width. Officially, the tornado’s width is listed as 1,500 yards (0.85 miles).

The 1.21.2 update is now live! We are aware of an issue with the lobby that did not appear during testing. Everything else should be working as normal though. Enjoy!

Tornadoes in Mexico's northeastern Coahuila Province, which borders SW TX, aren't uncommon. However, this midnight tornado on March 22nd, 2000, was possibly the most violent tornado of the year. Scouring desert/sandy terrain SW of Ciudad Acuna, it tracked N for 25+ miles.
