The National Weather Service has confirmed that a thunderstorm early Monday morning, in fact, produced a small tornado. The storm produced destroyed trees and damaged a building or two. Most of the damage was caused by straight line winds. But on closer inspection the NWS determined that an EF-1 tornado with winds of 110mph was responsible for some of the damage.
This tornado was just 50 yards wide and was on the ground for a mere half mile. A very brief tornado that struck at 5:05am Monday. Although brief, it was still dangerous and fortunately no one was hurt or killed.
As for Monday night into early Tuesday morning, three tornadoes were reported to the National Weather Service. They occurred in Plymouth, Polk and Hardin County. Those tornado reports were part of 43 reported across the country on Monday. There is speculation that some damage in far northern Iowa might also be tied to a 4th tornado. That’s up to the National Weather Service to determine and when they have more information we’ll certainly pass it along to you.
