An area of low pressure over southern Manitoba the morning of the 15th moved to near southern Hudson Bay by the morning of the 16th. A cold front associated with this low moved across the Northland during the afternoon and evening hours of the 15th. A warm front had moved through on the previous day brought a warm and unstable airmass in its wake. The cold front then worked with this airmass to create severe storms from northeast Minnesota into northwest Wisconsin and western Lake Superior. Damaging winds accounted for most of the reports with these storms, although there was some marginally severe hail as well. Most of the damage was to trees, but some property damage to pontoon boats and a home also occurred.
