A low pressure system over the upper Midwest moved across the Great Lakes on June 18. Ahead of the low pressure system, a warm front moved over the area early on June 18 bringing temperatures into the mid-80s that afternoon. A cold front trailed the low pressure system and moved across the Great Lakes through the afternoon. Ahead of the cold front, several severe thunderstorms developed, including one storm that produced and EF-1 tornado in northern Stark County. Additional thundestorms dropped very heavy rainfall across the area, especially in the Akron Metro area, as rainfall flooded the Central Interchange and many roadways south of the city.||National Weather Service Survey Team decided an EF-1 tornado touched down in Uniontown near the Uniontown Fire Department and traveled east southeast along an intermittent path for approximately 9 miles through Lake Township. Most of the damage observed was to trees that were uprooted or snapped part of the way up of the ground. A newly constructed dairy barn in Marlboro township near State Route 44 and St. Peters Church Road had significant roof damage. Minor roof and siding damage was observed along the tornado path. A swath of straight line wind damage occurred south of the tornado track from the north side of Canton to Louisville. Numerous trees and power poles were brought down, with at least one tree falling on a home. Several people were trapped in an SUV due to the downed power poles.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 20:29 UTC and running to 00:53 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Marginal Risk. The outlook in force was issued at 20:01 UTC.

5 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.
