The remnants of what was Tropical Storm Bill moved east, through northern Kentucky during the morning hours, reaching near Portsmouth during the mid afternoon hours.||Showers were more persistent from northern Vinton County and the Hocking River Valley on north. Lines of thunderstorms formed ahead of the low pressure center during the early afternoon and moved north. One brief tornado was confirmed in Washington County on the mesoscale comma head of one short convective line.||Rain totals of 1.5 to 2.5 were common over grounds that had become wet during the past week. Minor flash flooding occurred.

A brief EF0 tornado occurred off of Tullis Road, southwest of Bartlett. The estimated strongest wind gust was around 85 mph.||Several trees were uprooted and numerous large branches were snapped. One house and an outbuilding were damaged, mainly to the roof and siding. Also, a small aluminum boat was thrown from the edge of the pond, 140 yards and wrapped around a tree.

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

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 16:34 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.

10 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.
