 Brief Description: An F1 tornado touched down to the northeast of Arcadia in northeastern Hancock County. The initial touchdown occurred just south of State Route 12 and to the east of County Road 330. From this location the tornado moved northeast and strengthened to F2 intensity as it entered the southwest end of Fostoria. Two businesses were heavily damaged on the outskirts of Fostoria along State Route 12. One of the two, a fertilizer business, had two of it's four buildings completely leveled and the remaining two heavily damaged. A nearby gas storage facility had two large storage tanks damaged. Nearby, the tornado derailed two railroad cars near the West Tiffin Street crossing and toppled 19 high voltage transmission poles interrupting power for a large area. Extensive damage was done to neighborhoods on the southwest side of Tiffin with Jeannette Drive, Vickie Lane and West Tiffin Streets hardest hit. As the tornado neared downtown Fostoria it tore the roof off of a high school which allowed rain water to enter the building and damage all three floors. Total damage to the school was estimated to be well over $500,000. Just east of the school, the community hospital was hit and sustained over $1 million in damage. The tornado lifted just east of the hospital and touched down a second time on the northeast side of Fostoria (Seneca County). In Fostoria, eight homes were destroyed with nine more homes damaged enough to be declared uninhabitable. An additional 60 to 70 homes sustained minor damage with dozens of cars damaged in varying amounts. Hundreds of trees and power poles were downed along the damage path which was around 50 yards in width.

 Brief Description: EVENT NARRATIVE: 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. EPISODE NARRATIVE: 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.

 Brief Description: EVENT NARRATIVE: The tornado touched down in Auglaize County at 1059 EST and continued into Allen County at 1102 EST before lifting at 1103 EST. The path width was 110 yards in Auglaize County and 20 yards in Allen County. The tornado traveled for 2.53 miles in Auglaize County and then 1.39 miles in Allen County. The damage was consistent with winds around 110 miles per hour in Auglaize County and 75 miles per hour in Allen County. The tornado was rated an EF2 in Auglaize County and an EF0 in Allen County. The tornado initially touched down southwest of Cridersville where the tornado destroyed a barn. The tornado briefly lifted and then touched down in Cridersville. Damage in Cridersville included roofs blown off of houses, a house shifted off of the foundation, a house with major structural damage, and a half collapsed brick gymnasium. Objects were also impaled into the side of buildings. The tornado again briefly lifted and then touched down again in Allen County near McClain Road, north of Hume Road. At this location a quarter of a metal roof was pulled off of a metal barn. Damage estimates in Auglaize County are 230,000 dollars and in Allen County damage estimates are 8,000 dollars. EPISODE NARRATIVE: A historically deep low pressure system sent a very strong cold front into a marginally unstable, but very sheared environment. A line of storms formed west of the area overnight and moved into the region during the peak heating hours of the day. Severe wind gusts occurred along the entire line with multiple tornadoes occurring around the region as well.

 Brief Description: This tornado originated in Van Wert county and moved across Paulding county into Putnam county about 4 miles west southwest of Continental. NWS ground and aerial survey found F3 damage as the tornado entered Putnam county, striking a mobile home and killing a husband and wife. The tornado moved northeast across the northwest corner of Putnam county, quickly weakening to an F0 as it exited the county 4.5 miles north of Continental. M72MH, F67MH 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: An F1 tornado touched down southwest of Tiffin near the Seneca County Airport. The tornado moved east northeast and strengthened to F3 intesity as it crossed U.S. Highway 224 and moved into Tiffin. The Honey Creek subdivision along County Road 19 near US 224 was hard hit. Six homes on Nantucket Drive in the subdivision were destroyed and many other homes damaged. As the tornado continued across the southern part of Tiffin it leveled a business along State Route 231 and destroyed several homes on Siesta Drive just east of State Route 231. A retirement community along St. Francis Avenue and just north of Siesta Drive was also hard hit by the tornado. Eight homes in the community were destroyed with five more damaged enough to be declared uninhabitable. Another 25 homes sustained lesser amounts of damage and several cars were found lying upside down. The tornado weakened to F2 intensity as it crossed State Route 100 and moved over Greenlawn Cemetary. From the cemetary, the tornado began to move in more of a northeasterly direction and briefly weakened to F1 intensity as it passed to the east of Heidelburg College. The tornado reintensified to F2 as it crossed State Route 18 and continued northeast across open country where it damaged many more homes and buildings. The tornado reached strong F3 intensity for several miles to the northwest and north of Republic. A 24 year old male was killed and two other people seriously injured when a home in Scipio Township on County Road 38 near County Road 43 was swept off of it's foundation. Two other homes nearby were also leveled. The tornado remained on the ground for another ten miles and gradually weakened to F2 intensity. It finally lifted south of State Route 18 near Fireside. Later, the same parent thunderstorm spawned another tornado a few miles away in Huron County. Overall, this tornado destroyed 32 homes and businesses, heavily damaged another eight and slightly damaged around 70 homes in Seneca County. Dozens of cars were also damaged and destroyed with downed trees and power poles numbering in the hundreds. The damage path from this tornado was roughly 21 miles in length and over 200 yards in width at times. M24PH

 Brief Description: This tornado originated in Van Wert county and crossed into Paulding county 3 miles southwest of Roselms and exited Paulding county about 2.5 miles southeast of Oakwood. NWS ground and aerial survey found F3 damage along the entire path in Paulding county, with only one structure remaining standing in the town of Roselms, in which the town residents had taken cover in the basement. 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.

 Brief Description: EVENT NARRATIVE: The tornado touched down along Highway 109 just north of County Road A and moved northeast, impacting several homes, trees and power lines. Several homes were severely damaged or destroyed (DI:FR12 DOD: 8). However, improper anchoring of some of the homes resulted in a failure on all walls, resulting in their destruction. Several trees were uprooted or damaged, including through the Maumee State Forest. The tornado ended near the Fulton/Lucas county line. The maximum width of the tornado was around 700 yards with maximum wind speeds estimated around 130 mph. Damage is estimated at $500,000. EPISODE NARRATIVE: A warm front worked north towards lower Michigan during the evening hours of the 5th. Storms were initially slow to organize, but quickly intensified and became supercellular. One of these storms tracked into Fulton county and quickly spawned a tornado north of Liberty Center. The tornado remained on the ground for roughly 7 miles producing damage along its track before dissipating near the Fulton/Lucas county line.
