17 damage points were recorded along this path by NWS IND, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

• Additional tree damage, mostly limbs.
• Board from roof driven into ground in convergent pattern.
• Older house minor roof damage.
• Splatter on home north of tree damage. Some branches appear unhealthy.

A surface low crossing Indiana from west to east brought a warm front northward through the region. The resulting increase in instability, coupled with adequate wind shear both through the 0-6 km layer as well as near the surface, generated scattered thunderstorms over southern and eastern portions of the region. A few storms produced isolated large hail/damaging winds in the afternoon, before two weak tornadoes were spawned later in the day over east-central Indiana.

NWS Survey confirmed an EF0 skipping tornado tracked 0.57 miles through the town of Summitville. The initial touchdown was west of the waste water treatment plant in a grove of trees. At the plant, a poorly secured roof was partially lifted and pieces strewn downwind in a convergent pattern. A 2x4 was planted into the ground from the southeast which was opposite of the general damage direction. The tornado then skipped through town causing tree and roof damage before causing more significant damage along Mill Street. There, several large tree limbs damaged a car and home with insulation splattered across 3 of the 4 sides of the home. Small amounts of mud splatter was also noted through town. Damage then briefly lessened near the school before 2 large and unhealthy oak trees were snapped. The tornado lifted afterwards with no additional damage.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 18:29 UTC and running to 22:55 UTC.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 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.

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.
