Date: 1994 and 1995: Location: Tornado Alley: Also known as: Verification of the Origins of Rotation in Tornadoes Experiment 1: Outcome: Documented an entire tornado, which, in conjunction with deployment of the NEXRAD system, helped the National Weather Service to provide severe weather warnings with a thirteen-minute lead time, and reduce false alarms by ten percent.
Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis is a volatile process and the intricacies of many of the mechanisms of tornado formation are still poorly understood. [1] [2] [3] A tornado is a violently rotating column of air in contact with the surface and a cumuliform cloud base.
The F4 tornado was the largest tornado on record at the time with a peak width of 2.5 miles (4.0 km) as it struck Hallam, Nebraska. [214] This is the first time a High Risk did not appear until the 01Z outlook within an outlook cycle, which has occurred one additional time since (on April 30, 2010).
Severe tornado damage occurs with an EF3 tornado, which has wind speeds of 136 to 165 mph. Some walls of well-constructed houses can be torn off. Most trees in the path of the twister will be ...

[1] The program, sponsored by the United States National Weather Service , issues recognition to communities and sites across the country that demonstrate severe weather readiness.
Two tornadoes that tore through the urban core of Tallahassee on May 10 converged at the Capital City Country Club to continue their miles long march of destruction.
Reliably predicting tornado intensity and longevity remains a problem, as do details affecting characteristics of a tornado during its life cycle and tornadolysis. Other rich areas of research are tornadoes associated with mesovortices within linear thunderstorm structures and within tropical cyclones.
May 10, 2024, could possibly go down in history as Tallahassee's worst tornado outbreak ever. Three different tornadoes, two of them EF-2 tornadoes, hit the area Friday.
