CHESTERFIELD, Mo. — The National Weather Service completed the survey on Thursday of the Wildwood and Chesterfield damage from Wednesday’s storm.
The NWS confirmed an EF-1 tornado formed just east of Highway 109 in Wildwood at 2:50 p.m. on Wednesday. The tornado reportedly dissipated in the Chesterfield Valley south of the Missouri River at 3:00 p.m.
The NWS issued the tornado warning around 3:00 p.m. that extended until 4:00 p.m. for some parts of St. Charles County, St. Louis County, and St. Louis City.
A tornado watch was not issued before the tornado warning on Wednesday, which means the warning was uncertain compared to recent storms.
A Missouri State Highway Patrol spokesperson told FOX 2 minor damage was reported around six homes west of St. Louis County, but no injuries have been reported.
The EF-1 tornado led to structural damage, several downed trees and power lines, leaving several thousand Ameren customers without power for a short period of time.
