The short-lived EF0 twister packed winds of up to 75 mph and traveled about one-third of a mile just north of Black Rock, said meteorologist William Churchill of the National Weather Service in Memphis. Churchill called the 100-yard-wide tornado a "spin-up" that was created by the outflow of a severe thunderstorm.
The tornado, the state's 13th confirmed twister this year, formed at 2:37 a.m. Tuesday as a strong cold front crossed the state.
The Weather Service also confirmed two tornadoes touched down in Madison and Newton counties Monday night. An EF2 tornado with winds of up to 135 mph destroyed the Parthenon post office.
The Lawrence County tornado uprooted trees and tore metal roofing off chicken houses north of town, said Black Rock Mayor Bonnie Ragsdale, who watched the storm blow through her town.
"It went right behind my house," she said. "I have a metal RV shed that I didn't think would make it. I still don't know how it survived all that wind."
