18 damage points were recorded along this path by NWS IWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 94 mph.

• South half of roof torn off, wuth trusses in place. No other indications of structure damage. Also, trees and other buildings showed no impacts. Winds reduced to lowest level.
• Pictures from soclal media show from (west side) of barn being pushed in withsigns of minor damage out the east side. Roof intact with no damage. PIcture is from EMA.
• Roof removed from mobile home but laid right next to it on the NW side. One side of the trailer buckled in on the SE facing side and bulging on NW side Surrounding trees appear untouched. Wind speed lowered to lowest level.
• Garage and Well house damaged. Location estimated.

Low pressure moved northeast into Lower Michigan with a trailing cold front across northern Indiana. Strong bulk shear in excess of 85 knots, combined with CAPE on the order of 500 J/KG and 0-1 km helicity values over 150 m2/s2 set the stage for a few lines of showers to develop. The low topped nature of the activity prevented lightning from developing despite strong updrafts at times. Pockets of wind damage occurred as a result of microbursts, with damage consistent with tornadoes being found in 2 locations within the swaths of damage.

Indications of rotation were found on the northwest flank of a swath of microburst winds. The tornado appears to have touched down near a residence on East County Road 400 North, east of North County Road 150 East. A garage and well house suffered some damage. A barn on the northeast corner of the property suffered damage to the sides and roof, with debris being carried up to a half mile to the northeast. As the tornado crossed the road, power poles were snapped. It quickly moved over open fields until encountering a small property where 2 pine trees were snapped about half way up and the entire roof of a log cabin/cottage was picked up and thrown into a wood area to the northeast of the property. A picnic table and swing were thrown to the northwest into trees and another building. The tornado was likely in the process of lifting at this time with all debris left in the woods. No injuries were reported.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
