Severe storms developed ahead of an advancing cold front on the afternoon and evening of the 10th. A few tornadoes occurred, and there were also reports of large hail and damaging winds.

An EF2 tornado caused damage along the White River and just a couple of blocks on land adjacent to the river. It was apparent that a portion of this tornado was a waterspout in the river. A log house and its adjacent garage were destroyed. The house had its roof and part of its back wall torn off, and the structure was shifted on its foundation. Several other houses were damaged, primarily on their roofs. One house had a covered porch torn off and another had a tree fall against it. A four-slip boat dock was overturned on the White River and two boats were sunk. Hundreds of trees were snapped off or uprooted.

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 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 19:36 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.
