1Most severe tornado damage; see Enhanced Fujita scale 2Time from first tornado to last tornado
The Tornado outbreak sequence of March 18–24, 2012 was a long lasting tornado outbreak that occurred due to a slow moving, but powerful trough and cutoff low. The outbreak began in the Great Plains, where, over a two-day period, several tornadoes touched down, some of which were significant. The North Platte area was damaged by an EF3 that was produced by a supercell that spawned many tornadoes throughout its lifespan. The tornadic activity then shifted the Southern United States over subsequent days, particularly in Louisiana and Mississippi.[2] These states were struck by a series of tornadoes for 3 days, most of which were relatively weak on the Enhanced Fujita Scale. However, a few reached EF2 intensity and caused considerable damage. Tornado activity continued across the Ohio Valley on the 23rd, with one confirmed fatality in southern Illinois.
As a powerful trough ejected into the Central Plains on March 18, the Storm Prediction Center issued a Slight risk for Severe Weather stretching from southern Nebraska to western Texas. That evening, many supercells evolved across the Texas Panhandle and Oklahoma, producing large hail and damaging wind gusts. As the supercells moved towards the northeast, four tornadoes were produced across western Oklahoma, all rated an EF0 on the Enhanced Fujita Scale. Early that night, a tornado-producing supercell moved across southwestern Nebraska, where four tornadoes were confirmed. The first was an EF3, the second was an EF1, the third was an EF3, and the fourth was an EF2. Severe damage was noted just to the west of the city of North Platte, Nebraska. The following day, the Storm Prediction Center issued a Moderate risk of Severe Weather, encompassing much of central and eastern Texas, into southeastern Oklahoma and extreme western Arkansas. Although this event was not as severe as initially anticipated, EF2 tornadoes caused severe damage in Texas as they impacted areas in and around Devine, Gardendale, and Lytle.[citation needed]
A slight risk was issued for parts of the Ohio Valley, but notable tornado activity was not expected. However, several tornadoes touched down across Indiana, Illinois, Ohio, and Kentucky. Supercell thunderstorms developed and produced large hail as well. One high-end EF1 tornado caused considerable damage to homes in the Louisville metro area.[3] An EF2 tornado caused one fatality in southern Illinois when a mobile home was thrown and completely destroyed.[4] On the 24th, an isolated EF0 touched down in Florida as the outbreak moved eastward and came to an end.
