Widespread showers associated with an area of low pressure grew into low-topped supercells across eastern Minnesota during the afternoon as the activity encountered greater instability. Strong low level shear helped produce six tornadoes from central and east central into northwest Wisconsin. There were three EF1 tornadoes and three EF0s. To many, the Silver Lake tornado appeared stronger than an EF1, but this was likely due to the high amounts of moisture in the air which allowed the condensation funnel to grow large. Damage along its path suggested a peak wind speed of 105 mph, a high end EF1.
