Share story

An isolated severe thunderstorm tracked across southern Minnesota Friday. The cell started near Cottonwood and blew through Redwood Falls, Gaylord, Arlington, Jordan, and Belle Plaine as it clipped the south metro. Some spotty tree damage occurred along the path.

There may be a few isolated evening thundershowers Friday night, but severe weather is not likely.
