		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: EVENT NARRATIVE: A devastating tornado moved across portions of northern Wood County during the late evening hours of June 5th. The tornado reached a peak intensity of EF4 and was responsible for the deaths of seven people. Five of the victims died immediately with the other two passing away from their injuries at later dates. The initial touchdown occurred east of Perrysburg along Oregon Road just to the north of the Ohio Turnpike. The tornado then moved east northeast toward Toledo Metcalf Field as an EF0 to EF1. The tornado intensified to an EF2 as it crossed East Broadway Street. Over two dozen homes in a neighborhood bordered by East Broadway to the west and State Route 795 to the north and east were heavily damaged or destroyed. The worst of the damage was along Shawnee and Neill Avenues in this neighborhood. The tornado then crossed State Route 795 and followed the highway toward Metcalf Field. The tornado intensified to EF3 at that time. Several homes along Moline-Martin Road were destroyed between State Route 795 and Metcalf Field. An occupant of one of the homes, an 87 year old man, was injured by the tornado and later died. As the tornado approached Metcalf Field it crossed a railroad yard and overturned a couple dozen railroad cars. The tornado then moved across the southern end of the airport grounds and destroyed the Lake Township Administrative and Police Department building located just northwest of the intersection of Cummings Road and State Route 795. A 20 year old female was killed by the tornado just outside of the police department. She had left her vehicle along with her boyfriend and child to seek refuge in the police station. She was caught outside and was reportedly killed by flying debris. At the police station, the tornado destroyed at least six police vehicles and one emergency response vehicle. The emergency response vehicle was found over 1000 feet away from its original position. One police vehicle was found wrapped around a large tree. After doing extensive damage to an agricultural business, the tornado struck the Lake Local School District complex along State Route 795 and Lemoyne Road. Lake High School took a direct hit from the tornado and was damaged enough to be considered destroyed. The nearby middle and elementary schools sustained considerable roof damage. The high school gymnasium was scheduled to hold a commencement ceremony for the graduating senior class on June 6th. Large sections of the gymnasium collapsed. A field house, cafeteria and auditorium adjacent to the high school were destroyed. At least eight school buses were overturned and destroyed by the tornado. The tornado continued to move parallel to and just north of State Route 795 at EF3 intensity. A 56 year old female was killed by flying debris while driving her car on State Route 795 near the school complex. The woman's daughters were following in another car which was also destroyed. The daughters both sustained minor injuries. The tornado continued east northeast and crossed Interstate 280 just north of the State Route 795 interchange before moving across open fields for about a mile. The tornado may have briefly weakened to EF2 intensity, but then strengthened back to EF3 intensity as it crossed Bradner Road to the west of Millbury. The tornado destroyed several homes in a neighborhood bordered by Bradner Road to the west and Cherry Street to the south. A 47 year old man was killed in house on Case Road in this neighborhood. The man's daughter was the valedictorian of the graduating senior class at Lake High School which was destroyed by the tornado. The tornado then intensified to EF4 as it approached Main Street on the north side of Millbury. Over a dozen homes were destroyed or heavily damaged along Main Street. A 36 year old woman and her four year old son were killed in one of the destroyed homes on Main Street. The woman's 37 year old husband died on June 12th from injuries sustained from the tornado. Several more homes were destroyed or heavily damaged on Hille Drive and Woodville Road before the tornado crossed North Fostoria Road and moved into Ottawa County as a weak EF3 or strong EF2 tornado. This tornado was on the ground for around six and a half miles in Wood County and destroyed or heavily damaged over 60 homes. Dozens of additional homes sustained minor damage with another couple hundred homes affected by the storm. Dozens of vehicles were also destroyed. Hundreds of trees were toppled or snapped by the tornado along the damage path which was up to 400 yards in width. The tornado debarked some of the larger trees along the damage path. At least one high tension utility pole was toppled by the tornado and widespread power outages occurred in Millbury and Walbridge. Damage to the Lake Township infrastructure was estimated at five million dollars with tens of millions of losses to the Lake Local School District. The exact number of injuries caused by this tornado is unknown, but at least 17 people had to be hospitalized in nearby Toledo. Debris from this tornado has been found dozens of miles away, including on some of the islands in western Lake Erie. EPISODE NARRATIVE: A stationary frontal system stretched across the lower Great Lakes on the morning of Saturday, June 5th. This resulted in a very warm and humid airmass over northern Ohio. Outflow boundaries from earlier storms interacted with the stationary front to initiate thunderstorm development during the afternoon hours across inland northern Ohio. One of the stronger thunderstorms produced tornadoes in Richland and Holmes Counties. There were also a few reports of straight line thunderstorm wind damage. A rapidly deepening area of low pressure moved quickly east across southern lower Michigan during the evening hours. This low eventually moved across Lake Erie during the early morning hours of the 6th. Showers and thunderstorms developed across northern Indiana during the evening hours. These storms intensified and moved east along the stationary front and into Northwest Ohio. A devastating EF4 tornado developed over Wood County a little before midnight. This tornado moved into Ottawa County before dissipating. Seven people were killed and dozens of homes destroyed by the tornado. A weaker tornado also moved across portions of Lucas County. A third round of storms developed during the early morning hours of the 6th ahead of a cold front trailing the low. These storms moved across northern Ohio and produced pockets of damage. An EF1 tornado occurred in Ashtabula County around daybreak. A total of five tornadoes occurred in northern Ohio on June 5th and 6th. These tornadoes killed seven people, injured dozens and destroyed or damaged over a 100 homes. A school and a public administration building were also leveled. Damage estimates easily topped $100 million.

		Brief Description: A multiple vortex tornado tracked across the southern part of the county. The tornado damaged or destroyed 56 mobile homes and 27 single family homes. Several barns and sheds were destroyed and numerous trees were downed. No serious injuries or deaths occurred with this tornado. A low pressure system with an unusually strong mid and upper level jet streak was moving across the Great Lakes with an associated cold front moving across the upper Ohio valley. Thunderstorms developed across Indiana and moved into West-Central Ohio around mid-afternoon with a distinct bow echo causing wind damage from near to Lima to southeast of Columbus. On the southern edge of the first line of storms, a supercell developed over Central Indiana. This storm evolved into a bow echo and swept across the Dayton metro area causing extensive wind damage and a brief tornado in Greene county. Another supercell developed near Cincinnati and moved southeastward along the Ohio River. This storm produced the F3 tornado in Clermont county.

		Brief Description: A tornado touched down west of Circleville, pulling a small shed off of its foundation and destroying a section of a construction building. after this, the tornado lifted and then touched down in a more developed area in town. It destroyed a building housing two businesses and ripped the roof off of a section of a strip mall, ejecting furniture from inside the structure. A large sign weighing several hundred pounds was ripped from its foundation and blown twenty feet away. A tractor trailer with a load of 18 to 19 tons was blown over and dragged ten feet away from where it landed. The tornado then proceeded to a housing development where several homes were destroyed, several roofs ripped off, and garages either destroyed or moved from their foundations. Trees were twisted and broken off at their bases and carports were also torn from nearby houses. A cold front pushed east from Illinois and Indiana during the afternoon hours and combined with a vigorous upper level disturbance that dropped into the Ohio Valley from the lower Great Lakes region. These factors prompted a squall line to develop ahead of the cold front that moved southeast through the Wilmington Ohio (ILN) county warning area before entering northeast Kentucky and southeast Ohio.

		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. 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: EVENT NARRATIVE: A strong tornado moved into western Ottawa County from Wood County during the late evening hours of June 5th. The tornado entered the county at 11:30 pm EDT as a weak EF3 or strong EF2 tornado. A couple homes on Trowbridge Road just east of the county line were heavily damaged. The tornado then continued east northeast to just north of the intersection of Billman and Trowbridge Roads where a few more homes were significantly damaged. After crossing Billman Road, the tornado took a turn to the right and intensified back to EF3. The tornado crossed Reiman Road just south of Trowbridge Road and finally lifted just before reaching Bolander Road. Around a dozen homes near the intersection of Trowbridge Road and Reiman Road were damaged. In Ottawa County, a total of 11 homes were destroyed with another 14 homes sustaining major damage from the tornado. Around 20 additional homes sustained lesser damages. This tornado was on the ground in Ottawa County for just over two and a quarter miles and had a maximum width of around 200 yards. Two injuries were reported. EPISODE NARRATIVE: A stationary frontal system stretched across the lower Great Lakes on the morning of Saturday, June 5th. This resulted in a very warm and humid airmass over northern Ohio. Outflow boundaries from earlier storms interacted with the stationary front to initiate thunderstorm development during the afternoon hours across inland northern Ohio. One of the stronger thunderstorms produced tornadoes in Richland and Holmes Counties. There were also a few reports of straight line thunderstorm wind damage. A rapidly deepening area of low pressure moved quickly east across southern lower Michigan during the evening hours. This low eventually moved across Lake Erie during the early morning hours of the 6th. Showers and thunderstorms developed across northern Indiana during the evening hours. These storms intensified and moved east along the stationary front and into Northwest Ohio. A devastating EF4 tornado developed over Wood County a little before midnight. This tornado moved into Ottawa County before dissipating. Seven people were killed and dozens of homes destroyed by the tornado. A weaker tornado also moved across portions of Lucas County. A third round of storms developed during the early morning hours of the 6th ahead of a cold front trailing the low. These storms moved across northern Ohio and produced pockets of damage. An EF1 tornado occurred in Ashtabula County around daybreak. A total of five tornadoes occurred in northern Ohio on June 5th and 6th. These tornadoes killed seven people, injured dozens and destroyed or damaged over a 100 homes. A school and a public administration building were also leveled. Damage estimates easily topped $100 million.

		Brief Description: EVENT NARRATIVE: A new rotating supercell formed south of thunderstorm complex that caused the tornado and strong downburst in western Athens County. A new tornado formed. Significant structural damage to farm buildings and a few homes occurred along Eden Ridge Road. This road is also County Route 50. The tornado path then went across State Route 124 between community of Reedsville and Eden along the Ohio River. A majority of the mobile homes affected were in this vicinity. In addition, a well built single family home and its detached commercial grade garage were completely destroyed. The foundations of both structures were wiped clean. The EF3 damage included this area along State Route 124. Maximum wind gusts of 150 mph were estimated. The county reported 22 structures destroyed or having major damage, including mostly mobile and single family homes. However, one car repair shop was also included. Another 20 homes were affected or had minor damage. Around a dozen outbuildings were damaged or destroyed. One male received rib and leg fractures when his truck was flipped over while he was in it. A woman was injured when she was pinned in rubble from her mobile home. In the dark, her barking dog helped first responders find her faster. A total of 6 people were injured, 2 seriously. This tornado crossed the Ohio River and killed a man immediately on the other side of the river in southern Wood County of West Virginia. EPISODE NARRATIVE: A cold front, in tandem with strong mid and upper level forcing, produced a severe weather outbreak in southeast Ohio into extreme western West Virginia during the late afternoon and evening of Thursday the 16th. The setup featured a 45 knot mid level flow and a 95 knot upper level jet. Matter of fact, a larger area of showers, associated with a warm front, had moved across southeast Ohio and West Virginia during the morning and midday hours. This kept the surface based instability at a minimum. However, new cells formed further west during the mid afternoon over western Ohio. It was this new cluster of convection that would intensify due to the strong mid and upper level dynamics. Several of the new cells formed and intensified on the southern or southwestern flank of the overall larger area of showers and thunderstorms. This area of convection stretched further to the northeast into eastern Ohio and western Pennsylvania. This allowed an unimpeded low level moisture inflow into the new development. Surface dew points ahead of the cold front reached into the mid 60s. Most of the severe thunderstorms exhibited strong rotation, resulting in the spawning of 5 tornadoes. Four of these 5 tornadoes were in Ohio. One of the 4 Ohio tornadoes crossed from Fairfield County into western Perry County. Another 1 of the 4 crossed from Perry into northwestern Morgan County. One tornado patch was solely in western Athens County. The damage continued another 10 miles in Athens County from a strong rear flank downdraft. Finally, the last of the 4 tornadoes in Ohio crossed the Ohio River from northeastern Meigs County into southern Wood County in West Virginia. From storm surveys, this was the strongest tornado. The last tornado path in this outbreak was solely in western West Virginia. Luckily, there were no fatalities in southeastern Ohio. However, there was one death on the West Virginia side of the Ohio River.

		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.

		Brief Description: EVENT NARRATIVE: A tornado touched down in Wayne County two miles southwest of downtown Wooster around 5:26 pm. This tornado strengthened to EF2 intensity and continued on the ground for over 11 miles before finally lifting two miles west of Dalton. Extensive damage occurred along the damage path with dozens of homes and buildings damaged. After the initial touchdown, the tornado quickly intensified to an EF2 as it continued on the ground to the east northeast. The tornado crossed Prairie Lane and Timken Road and then moved across St. Mary's Cemetery. Damage at the cemetery was extensive with 80 of 81 large trees knocked down and over two hundred gravestones broken or toppled. From the cemetery, the tornado crossed Madison Avenue and moved across the Ohio Agricultural Research and Development Center (OARDC). Significant damage occurred on the OADRC campus with several buildings severely damaged. A laboratory in one the buildings was destroyed. Two historic homes on the property sustained significant roof damage and several greenhouses were destroyed. Two barns and a machine shop were also leveled. The 102 year old Secrest Arboretum on the campus lost over 800 trees and many research projects were damaged or destroyed. The tornado tossed and destroyed several vehicles and a lot of farm machinery was also damaged or destroyed. From the OARDC campus, the tornado continued east along Secrest Road damaging or destroying several homes and buildings. The tornado weakened to EF1 intensity as it crossed Sylvan Road and to an EF0 as it crossed Barnard Road. The tornado then remained either an EF0 or EF1 until it lifted near the intersection of Kidron Road and Old Lincoln Way just west of Dalton. A total of nine homes were either destroyed or sustained major damage. Another 90 homes sustained lesser amounts of damage. In addition, at least 50 barns, garages and other outbuildings were damaged of destroyed. Thousands of trees were also toppled along the damage path which was up to 150 yards in width. Twenty eight utility poles were knocked down in Wooster alone and high tension transmission lines were also torn down by the tornado. The downed transmission lines affected four substations and resulted in around a third of Wayne County loosing power right after the tornado. The OARDC campus was closed for over a week and two local school districts had to close on September 17th because of the power outages. Only one very minor injury was reported. EPISODE NARRATIVE: During the late morning hours on September 16th, a warm front lifted northward through Ohio allowing for a significant destabilization of the atmosphere. By early afternoon, a severe thunderstorm watch was issued for most of northern Ohio. Severe thunderstorms swept across Ohio ahead of a cold front beginning in the mid afternoon and lasting well into the evening. Two devastating tornadoes occurred in northern Ohio. An EF2 tornado touched down in Wayne County near Wooster. This tornado left an eleven and a half mile long damage path and damaged over a hundred homes and buildings. A second tornado touched down in southern Holmes County. This tornado was rated an EF1 and was on the ground for about three miles.

		Brief Description: EVENT NARRATIVE: A tornado touchdown was along Kimberly Road, about 4 miles from Nelsonville. The tornado reached maximum intensity along Matheny Road to State Route 691. Matheny Road is also called York Township Road 269. Damage was concentrated along Matheny Road and State Route 691. The low level circulation was evident in the damage along Matheny Road. Debris was strewn one way on the south side of the road, then in the opposite direction on the north side. One resident said, you could see stuff flying through the air. Then the noise got real loud and we ran into the house and into a closet. The house was just shaking. Several mobile homes were completely destroyed. Yet, some of these mobile homes were poorly anchored or not anchored at all. Many large softwood trees were uprooted or snapped at their trunks. Reports were received of several cows being lifted by the tornado. A hay bale weighing 1800 pounds was lofted into the air and set back down. The maximum wind gusts were estimated at 120 to 130 mph. A total of 7 people were injured. About 13 homes were destroyed, with dozens of other homes damaged. Since 1950, this is only the second confirmed tornado in Athens County. The previous tornado was a F1 during May of 1980. However, prior to 1950, 3 tornadoes have been reported in Athens County, back in July of 1896, April of 1922, and June of 1937. The June 1937 tornado killed 3. The storm in 1896 was reported in Glouster. However, historical accounts also describe a tornado in the late 1800s that destroyed a large grove of sycamore trees in the city of Athens. EPISODE NARRATIVE: A cold front, in tandem with strong mid and upper level forcing, produced a severe weather outbreak in southeast Ohio into extreme western West Virginia during the late afternoon and evening of Thursday the 16th. The setup featured a 45 knot mid level flow and a 95 knot upper level jet. Matter of fact, a larger area of showers, associated with a warm front, had moved across southeast Ohio and West Virginia during the morning and midday hours. This kept the surface based instability at a minimum. However, new cells formed further west during the mid afternoon over western Ohio. It was this new cluster of convection that would intensify due to the strong mid and upper level dynamics. Several of the new cells formed and intensified on the southern or southwestern flank of the overall larger area of showers and thunderstorms. This area of convection stretched further to the northeast into eastern Ohio and western Pennsylvania. This allowed an unimpeded low level moisture inflow into the new development. Surface dew points ahead of the cold front reached into the mid 60s. Most of the severe thunderstorms exhibited strong rotation, resulting in the spawning of 5 tornadoes. Four of these 5 tornadoes were in Ohio. One of the 4 Ohio tornadoes crossed from Fairfield County into western Perry County. Another 1 of the 4 crossed from Perry into northwestern Morgan County. One tornado patch was solely in western Athens County. The damage continued another 10 miles in Athens County from a strong rear flank downdraft. Finally, the last of the 4 tornadoes in Ohio crossed the Ohio River from northeastern Meigs County into southern Wood County in West Virginia. From storm surveys, this was the strongest tornado. The last tornado path in this outbreak was solely in western West Virginia. Luckily, there were no fatalities in southeastern Ohio. However, there was one death on the West Virginia side of the Ohio River.

		Brief Description: EVENT NARRATIVE: This tornado originiated in Fairfield County, but got stronger in western Perry County. The damage path widened as it crossed several north to south oriented roads. A convergent damage pattern was evident. Large trees were snapped along Avalon Road. A greater swath of tree and structural damage was along Otterbein Road. The damage path widened to as much as 800 yards, though the southern portion of the path was dominant. The tornado unleashed it worst winds as it continued east to encounter Palomino Road and County Township Road 138. At this stage, there was aproximately a 1 mile long and 100 yard wide path of EF2 strength winds, estimated at 110 to 120 mph. A manufactured home on Palomino Road was missing 95 percent of it roof covering and 40 to 50 percent of the roof supports and interior ceilings were missing. The woman inside was injured when a hallway door struck her in the back. There were at least 2 eyewitnesses to the actual tornado. Almost a mile east on County Township Road 138 a cluster of houses was heavily damaged. The worst damage was a newer 2 story single family home, but seemed to be of the manufactured home quality. Its roof and garage were completely blown off and thrown away. The tornado began to weaken as it headed across County Road 25. The tornado further weakened during its final 1.5 miles, ending near the intersection of County Roads 122, 123, and 134. About 8 homes were destroyed in this 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.
