And, the storm remained very close to the surface warm front. The tornadic supercell tracked at an average speed of 59mph moving farther away from the cyclone center with time. The south-to-north temperature gradient was very pronounced due to cooling produced by early morning storms and precipitation.
The new analyses show a long-lived supercell that developed very near the center of the cyclone produced the tornado, possibly where a warm front and a distinct dryline intersected. The storms of 18 March were associated with a rapidly moving cyclone that was not unusually intense. The researchers concluded there was no singular feature in the meteorological setting that would explain the extreme character of the Tri-State tornado. The authors include retired NSSL Director Bob Maddox, retired NSSL/CIMMS researchers Chuck Doswell, Don Burgess and Charlie Crisp, retired Storm Prediction Center (SPC) meteorologist Bob Johns and current SPC meteorologist John Hart, and Steve Piltz from the National Weather Service Forecast Office in Tulsa, Okla. The results, published in the Electronic Journal of Severe Storms Meteorology, revealed previous analyses of the surface weather conditions were inaccurate and led to misconceptions about where the tornado formed in reference to the existing weather system. Weather Bureau data on the Tri-State Tornado. Unfortunately, there is only one formal paper regarding the tornado and its meteorological setting.Ī team of eight severe storms meteorologists re-analyzed the event using all relevant U.S.
The MaTri-State Tornado was unusually severe, killing 695 people while it was on the ground for a record 219 miles crossing parts of Missouri, Illinois and Indiana.
