 Brief Description: The tornado was likely produced as the result of a line of thunderstorms overtaking an isolated supercell thunderstorm ahead of the line. The circulation which produced the tornado intensified shortly after the merger of the line and isolated supercell. The tornado developed near the intersection of Burris Road and Walnut Grove Church Road about 1 mile south of Ohio City. The tornado tracked to the east-northeast for roughly 2 miles before dissipating near Greenville Rd about 2 miles east of Ohio City. Damage along the first half of the tornado track was consistent with F2 intensity, with winds estimated at 140-150 mph and an initial path width of about 300 yards. In this area, 3 barns were completely destroyed, with another 5 sustaining damage. A garage was destroyed, and several houses received damage including roof, siding, and windows. Several grain bins were also damaged, along with other miscellaneous vehicle and property damage, including several tractors, a combine and other farm implements. Damage along the second half of the tornado track was consistent with F1 intensity, with the path width narrowing to about 25 yards. Several buildings sustained roof, siding, and window damage, with several instances of trailer and vehicle damage.

 Brief Description: This tornado touched down in the southwest corner of Van Wert County about 4 miles northeast of Willshire and moved northeast across the western portion of the city of Van Wert, and then crossed U.S. 30 and continued northeast before exiting the county about 7 miles east of Scott. NWS ground and aerial surveys showed the tornado quickly intensified to F4 about 5 miles southwest of the city of Van Wert near Zook road, where a 75 year old male was killed in his home. The tornado continued moving northeast as an F4 into the city of Van Wert, were it hit the Twin Cinemas and the Vision Industrial Park. At this point the tornado was about one half mile wide. 60 persons watching a movie in the cinemas, mostly children, took shelter before the tornado hit, with only minor injuries. Vehicles from the parking lot were thrown into the seats where the children had been sitting. An 18 year old male driving past the cinemas was thrown from his vehicle and killed. The tornado then destroyed five industries in the Vision Industrial Park, before moving north of U.S. 30, producing F4 damage to additional businesses and homes. The tornado weakened to F3 as it moved northeast and crossed into Paulding county. 164 homes were damaged in Van Wert county, and 43 were totally destroyed. 27 businesses sustained damage, with 5 totally destroyed in Vision Park. Three county engineer buildings were destroyed, with one house used by a township. Total damage in Van Wert county was near 30 million dollars. M18VE, M75PH On Sunday, November 10th, 2002 a cold front trailed from a deep surface low over northern Lake Michigan into central Missouri. Ahead of the cold front the KILN (Wilmington, OH) 1200 UTC sounding showed an unstable airmass with CAPE (Convectively Available Potential Energy) of 1148 J/kg and a Storm Relative Helicity (SRH) of 408 m/s2. Another sounding at 1800 UTC showed CAPE had increased on a modified sounding to 1313 J/kg, with SRH increasing to 587 m/s2. A broken squall line developed from Indianapolis to Fort Wayne Indiana and Defiance Ohio with the cold front. A small low topped supercell developed ahead of the line over Blackford county Indiana and was moving northeast at 50 MPH. This parent supercell produced 3 seperate tornadoes in Indiana (see StormData, Indiana, Northeast for more information) before crossing into Ohio. There the supercell intensified and a tornado touched down in Van Wert County Ohio, reaching F4 in strength as it reached the city of Van Wert. The tornado then moved northeast with a total path length of 53 miles, producing F3 damage in Paulding and Putnam counties, and F0 damage in Defiance and Henry counties.

 Brief Description: The same supercell that produced the weak tornado in Hamilton county also produced this tornado. This strong tornado initially began as three funnels which merged to one tornadoabout when it touched down on the southwest side of Anderson near exit 22 of Interstate 69. The tornado proceeded east-southeast for 5 miles, damaging 35 homes, five with major damage, and also one business. Over 50 trees were blown down, numerous power lines were blown down, and two grain silos were tipped over before the tornado lifted near Emporia. Due to advance warning and good visibility that day, everyone in the path of the tornado were awareof its approach, and was able to seek shelter and escape injury.

 Brief Description: Tornado touched down as as F1 at the Northcrest shopping mall on the northwest side of Fort Wayne. Damaged to mall and surrounding businesses. Cars flipped over in parking lot with one person injured. Tornado then briefly lifted and touched down one half mile to the northeast as an F2. Extensive damage to the Papermill subdivision with F2 damage to two homes, an office complex, a retirement home, and a steeple torn off a church. One injury at the retirement home and one in the subdivision. Tornado proceeded northeast with F0-F1 damage to the Concordia Seminary and adjacent structures before the tornado lifted on the northeast side of the Seminary grounds. Synoptic and mesoscale conditions and event summary for Saturday May 26th, 2001 A low topped supercell thunderstorm developed in Cass county Indiana, and moved northeast through the Fort Wayne metropolitan area and into northwest Ohio. This thunderstorm produced several tornadoes and numerous funnel clouds. The wind field was favorable for rotating storms on with strong veering in the KIWX Wind Profile. This was on the south side of a unseasonably cold closed upper low in the mid and upper levels. Surface temperatures in the lower 50s, and scattered showers were against strong thunderstorm development. However sunshine over central Indiana allowed enough heating for a thunderstorm to develop and quickly began rotating.
