WOW These cooking outflow boundaries with big instability, easterly surface winds beneath modest westerlies always produce the biggest, strongest wedge tornadoes in the Great Plains. WATCH OUT OKC #tornado threat 5-11 pm!

This video was my first ever Dakota mega wedge #tornado setup - the Manchester F4 on June 24, 2003. This was when I first realized the unstable warm frontal / outflow boundary zones during summer produce the largest, most violent tornadoes. They are often very slow moving, if not stationary, with the classic easterly under westerly wind profile and big instability. The El Reno mega wedge #tornado from 2013, as well as the Bennington, KS mega wedges from 2013 and 2016, the Pilger Twin EF4 tornadoes, Coleridge and Alpena days in 2014 were also similar setups. This year, the Spiritwood, ND and Gary, SD #tornado setups were also similar unstable warm front / outflow boundary zones with summer instability.

Check out the rapid motion on the backside of this violent wedge #tornado. I have chased many violent tornadoes over the last 30 years, and this tornado in southern Ms had the look of the strongest

A dangerous severe weather outbreak is threatening millions across the Midwest and Plains, bringing powerful thunderstorms, destructive winds, and the threat of tornadoes.

At least 17 tornadoes were reported from Oklahoma to Iowa on Thursday, including a large and destructive tornado that tore through parts of Enid, OK, injuring at least 10 people and damaging 49 homes. Today is day 2 of a multi-day severe weather event in the Great Plains and Midwest with the threat for tornadoes, damaging winds, and large hail this weekend into early next week. ABC News' Ginger Zee has more.

What's a "wedge" tornado? And how rare are "megawedge" tornadoes? There is no technical definition of a "wedge." Storm chasers consider wedge tornadoes to tornadoes that appear wider than they are tall. (For the tornado's height, they use the distance from the ground to the cloud base – AKA the "lifting condensation level". True tornado circulations extend up to 30,000 or 40,000 feet into the storm, so no tornadoes are *actually* wider than they are tall. We just can only see the part of the tornado that hangs down from the cloud base.) The tornado you see below occurred in Harlan, Iowa on April 26, 2024. It's the biggest I have ever seen. It was 1.1 miles wide, and had winds estimated by mobile Doppler radar up to 224 mph! Only 1 or 2 in 1,000 tornadoes grows larger than a mile wide – at least according to National Weather Service survey data. Realistically, that number might be significantly higher when counting inflow winds and ill-defined edges of the tornadic circulation, especially in rain-wrapped environments. (Where does the "tornado" end and the wind "around" the tornado begin?) MEGAWEDGE tornadoes are informally considered anything wider than 1.5 miles in diameter. The National Weather Service has only "officially" logged 30 megawedge tornadoes out of the 84,000+ in their database. The BIGGEST tornado on record occurred in El Reno, Oklahoma on May 31, 2013. It was 2.6 miles across! That said, researchers found evidence that the Mulhall, Okla. tornado on May 3, 1999 had a peak "core circulation" about 4.3 miles wide. In other words, that's the diameter of the 96 mph or greater winds. Let's hope 2025 doesn't feature any megawedges! If there are, we'll be streaming them in the MyRadar Weather app!

Check out this intercept of an EF3 #tornado at birth in the Dominator 3! Note the suction vortex that develops right in front of the vehicle as the dynamic pipe drills toward the ground. The Dominator allows us to get inside these tornadoes like no one else can safely, so we can record near-surface winds for #science

The most violent tornadoes can produce winds in excess of 300 mph. What's wild, is that theoretically, these winds can be even stronger. Here's the atmospheric process that makes this possible: 1/12

The Sulphur, Oklahoma tornado on May 9, 2016, was the ultimate wedge: A large, violent tornado with a well-defined funnel that was completely visible. I've seen a lot of big tornadoes, but none as visually striking as this one.

May 24, 2011 produced the strongest tornado I've ever witnessed near Chickasha Oklahoma. This was the last violent outbreak in Oklahoma. OKC is lucky a left split from Texas killed the storms just before the violent tornadoes entered metro #okwx

BIG PROBLEMS with #Dominator 3 after recent #tornado intercepts. We will be executing major repairs ahead of the uptick in severe weather starting Thursday Great Plains through Dixie Alley. See the nubbed out spike?!?

Final approach to the dust buster wedge #tornado with accidental probe launch in the rear inflow jet. The traffic and pedestrians delayed us about 60 seconds or we would have had a direct intercept. We spent a little too much time with the first 5-6 tornadoes with rapid cycles. Full wedge video:

Will Team Dominator get slapped by a tornado today? Tornadoes are possible for the northern plains this afternoon and evening.

Tomorrow night is one to watch in Alabama. Enhanced risk (level 3 of 5) now covers Birmingham, Tuscaloosa, Clanton, Sylacauga, Talladega and surrounding areas. Damaging winds and possible tornadoes with the line moving through after 5 PM - midnight before it weakens.

Team Dominator let it rip in #tornado intercept mode with two tornadoes chased from close range in Iowa! We could have easily intercepted the second tornado for science, but the traffic was too bad. It’s like Mario Kart out there in #Tornado Alley these days

Severe storms hammer southern Minnesota with multiple tornadoes, baseball-sized hail, and damaging winds hitting the region. The National Weather Service confirmed at least three tornadoes touched down Monday evening as extreme weather ripped through the region, with several areas placed under an emergency tornado watch before the systems moved through.
