Small, but potent thunderstorms caused tornadoes and a waterspout during the evening of August 26, 2019.

At around noon on Monday, August 26 there was a large swath of moderate to heavy rain marching eastward across Minnesota ahead of a cold front. As the rain moved off to the east, some sunshine appeared and a broken line of thunderstorms rapidly developed behind the main area of rain. Some of the cells were strong enough to produce tornadoes and a waterspout.

The waterspout was seen by many over Farm Island Lake in Aitkin County. This caused dock, boat and tree damage. Two tornadoes were surveyed in Mille Lacs County: an EF-0 tornado north of Milaca and an EF-1 south of town. The tornadoes caused damage to sheds, shingles, a chicken coop and at least one hapless trampoline.

This event, like the one on July 28, 2019 shared some similarities with the tornadoes of August 19, 2009.

The Chanhassen National Weather Service did a survey of the August 26, 2019 tornadoes in Mille Lacs County.

Below are storm reports collected from the National Weather Service.
