A large area of thunderstorms spread over the area ahead of a warm front on Saturday evening. The severe weather occurred along and south of the Interstate 94 corridor. A storm passing just south of downtown Battle Creek produced a tornado just after 11 PM EST. Parts of Calhoun and Kalamazoo counties also received heavy rain that produced flash flooding.

The tornado touched down near the intersection of Capitol Avenue and East Stafford Avenue just east of Goguac Lake and moved east just missing Riverside Elementary School and then moving along Chapel Hill Drive where it reached its peak intensity. The tornado then weakened as it moved across Interstate 194 before finally dissipating as it crossed 6 1/2 mile road. Three houses and Chapel Hill Methodist Church suffered partial loss of their roofs which along with approximately 100 snapped and uprooted trees resulted in a rating of EF1 along Chapel Hill Drive. The remainder of the track was rated EF0 where clusters of trees were uprooted or snapped with only minor damage occurring to houses in the path.

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 01:06 UTC.

42 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.
