Multiple rounds of showers and thunderstorms moved across parts of Ohio at the start of the month of April. An intense squall line raced through portions of southeast Ohio on the late morning of April 2nd, which spawned four tornadoes and caused numerous other locations to observe straight-line wind damage. Additional severe thunderstorms occurred late in the afternoon and into the evening of April 2nd, producing additional tornadoes and wind damage centered within southern and eastern Ohio. ||The multiple rounds of rain produced numerous instances of flash flooding around Ohio. Widespread rainfall amounts of 2 to 4 inches had fallen across southern and eastern Ohio, with localized amounts near 6 inches observed. Runoff from this rainfall, coupled with heavy rain occurring in West Virginia and Pennsylvania, caused moderate to major flooding along the Ohio River. Moderate flooding was observed first along the lower Muskingum River, with both McConnellsville and Beverly having surpassed their respective moderate flood stage. Drainage into the Ohio River eventually sent the river into flood on April 4th from north to south, with subsequent crests occurring into April 5th. Locations along the upper reaches experienced moderate flooding. In addition, Marietta exceeded major flood stage. Overall impacts were significant with numerous roads and structures observing flooding along the West Virginia side of the river.

A tornado formed along Erwin Hollow Road where several hardwood trees were snapped and uprooted. The tornado then moved northeast over a thick forest of mixed pine and hardwood trees between Erwin Hollow Road and Roberts Road where drone footage showed an extensive area of leveled hardwood trees and EF2 intensity was obtained. The drone footage and ground surveys then showed that the tornado weakened and the path became intermittent as it crossed Roberts Road, where a house was damaged when a tree fell on it. The last damage was noted along Oakland Road where several large pine trees were uprooted or snapped.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:01 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.
