The National Weather Service is conducting the annual Tornado Preparedness Drill between 9:30 a.m. and 10:30 a.m. Tuesday, March 7. The tornado was estimated to have winds between 85 and 95 miles per hour, also an EF1.

The preliminary findings indicated that the tornado was rated an EF-2, which indicates winds reached between 111 and 135 miles per hour.

A storm survey team from the National Weather Service confirmed that two tornadoes made brief touchdown near Knoxville on Monday night. The tornado damage path also exhibited multiple vortex characteristics at this point, yielding three distinct convergent areas within the parent vortex. The main threats are damaging winds, large hail and isolated tornadoes.

Then storms should impact the St. Louis metro area between 11 p.m. and 1 a.m.

An EF-1 tornado with peak wind speeds of 95 miles per hour traveled 7.5 miles through Williamson County, setting down at 10:41 p.m. 2.2 miles southeast of Carterville and lifting at 10:54 p.m. approximately 3.5 miles north of Marion. The tornado caused significant damage to Wells Manufacturing, with a partial collapse of walls and the roof. Several other homes sustained minor roof and tree damage, and one greenhouse was destroyed, according to the National Weather Service.
