EF1 tornado in Polk County, Minnesota

This tornado, which was partially wrapped in downburst winds and heavy rain, snapped various trees at a farmstead. After crossing highway 2 roughly two miles east-southeast of the highway 59 intersection, it blew in a large west facing overhead door on a shop and blew out the back wall. Peak winds were estimated at 100 mph.

The early morning hours of Friday, June 29th, remained warm and muggy. Just after midnight, temperatures were still in the 70s with dew points around 70. A line of thunderstorms moved into the Devils Lake area around 2 am CDT. This line of storms had several bowing segments, which are indicative of strong winds. The most obvious bowing segment between highway 2 and Interstate 94, where the most amount of damage occurred. The main bowing segment exited into north central Minnesota around 6 am CDT. Well behind the bowing thunderstorm complex, a mesoscale convective vortex (MCV) formed, and produced another round of widespread damaging winds.
