A line of severe storms moved through during the morning hours of February 28th. The main threats were damaging winds and flash flooding, however one tornado also occurred with this event.

The tornado touched down south of Millersport near the intersection of Millersport Road and Canal Road where tree damage was observed. The tornado then continued to the east and directly hit a farm on the north side of Canal Road. At this location, metal grain bins were tossed and rolled and trees were uprooted. A masonry wall was also flattened and numerous objects were impaled into the ground as well. A newly constructed barn had the roof removed and numerous pieces of sheet metal were strewn into adjoining fields. The tornado then continued on and hit two residences on Lake Road. A modular home had the roof completely removed and tossed and trees were uprooted. A barn was completely destroyed in the area as well. At another residence, one of the exterior walls was buckled from the wind blowing the door of the home open. Corn debris from a nearby field was driven into the ground. A stick was found driven into the siding on the front of the home.

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 General Thunderstorms Risk. The outlook in force was issued at 05:58 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The Cincinnati radar (KILN), 122 km away, was scanning. The volume nearest the touchdown began at 10:59 UTC.

25 more were confirmed in the United States that day.

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.
