A cold front trailing an area of low pressure over the central Great Lakes moved into western Ohio during the late evening hours of May 30th. Showers and thunderstorms developed in advance of this front and moved across northern Ohio during the early morning hours of May 31st. A few of these thunderstorms became severe with one producing a tornado.

A tornado touched down in northeastern Hancock County about two miles southwest of Arcadia near the intersection of Township Roads 214 and 254. The tornado continued northeast for about six miles before moving into Seneca County on the south end of Fostoria. The total tornado path length was over eight miles. The track was parallel to State Route 12 and about a mile to the south of the road. The tornado was initially an EF1 but strengthened to EF2 intensity after crossing County Road 330. The tornado returned to EF1 intensity just before reaching County Road 23 on the southwest edge of Fostoria. The damage path had a maximum width of around 100 yards. Around a dozen properties sustained damage from this tornado. At least two homes were destroyed with several others heavily damaged. Many outbuildings were also damaged. Hundreds of trees were toppled along the damage path. At least six people were treated at a Fostoria hospital for cuts and bruises.

An EF1 tornado continued into western Seneca County from Hancock County. The tornado entered the county on the south side of Fostoria and continued northeast for around two and half miles before dissipating near County Road 60. One home on the south side of Fostoria was damaged enough to be classified as destroyed. Many other homes in the city sustained roof or siding damage. At least 30 homes were reported to have limbs or trees on them in Fostoria alone. Several sheds and other outbuildings were also leveled. Hundreds of trees were toppled as well. This tornado had a damage path more than eight miles in length and up to a 100 yards in width.

42 minutes of warning. NWS CLE issued a tornado warning for this county at 04:47 UTC, 42 minutes before the tornado touched down, in force until 05:30 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:53 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.

18 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.
