 Brief Description: The tornado touched down again, hitting a farm at 1300 N and 100 W. A man suffered a broken leg here. Two hog sheds and a large grain bin were destroyed. A 200-yard swath of trees were uprooted to the northeast along the railroad tracks. Another man suffered back and chest injuries as the tornado continued to the intersection of 1300 N and Meridian Road and demolished the barn in which he stood. A 5th wheel camper was rolled 50 yards from its original position destroying it. The tornado continued to the next farm just south of 1400 N and 100 E. The barn was destroyed and the house suffered moderate damage, primarily from flying tree debris. The tornado snapped a utility pole, which fell on an 18-year-old boy, breaking his leg. Many trees and power lines were downed along the way. From here, the tornado continued until the Wabash/Kosciusko county line. Synoptic and mesoscale conditions for June 14th... A significant mid-level shortwave trough was located over Iowa on the morning of June 14th with an outflow dominated squall line across western Illinois. Rapid destabilization ensued later in the morning across eastern Illinois and northern Indiana with CAPES to 3500 j/kg by early afternoon. VAD wind profiles showed 850 millibar winds in excess of 50 knots in advance of the upper trough by afternoon and as storms developed along the left over outflow boundary across Illinois... they quickly became severe and organized into a large bow echo and moved quickly eastward into northern Indiana causing extensive wind damage. By late afternoon... a short segmented squall line developed just ahead of this bow echo squall line and extended from a St. Joseph to Fulton county line. Along the southern end of this line... an embedded tornadic supercell developed and interacted with a left over storm-scale outflow boundary to produce the Wabash/Kosciusko and DeKalb county tornadoes. The lack of significant low level shear likely prevented a much larger and more widespread tornado event especially across Whitley and Allen counties where several funnel clouds were captured on film but failed to touch down.

 Brief Description: The last farm was hit when the tornado was located just west of 1300 S and 400 E in Kosciusko County. Two barns, a garage, and several outbuildings were completely destroyed with some of the foundations swept clean. The house and two cars were severely damaged from large pieces of flying debris. A 17 foot boat was thrown about 20 yards and severely damaged. Most of the trees on this farm were destroyed. Debris from this farm was carried up to one half mile away as the tornado crossed 400 E and then lifted back into the clouds. Synoptic and mesoscale conditions for June 14th... A significant mid-level shortwave trough was located over Iowa on the morning of June 14th with an outflow dominated squall line across western Illinois.

 Brief Description: A NWS survey confirmed that a tornado that had caused damage across extreme eastern Cass county in Indiana crossed into Miami county and continued to cause damage as it moved just north of the Grissom Air Force base. The tornado dropped into a river valley and flipped over some conveyor machines in a quarry located in the valley. Damage to these was consistent with an F1 tornado. The tornado intensified as it moved into a area of houses in this valley. The first house that was struck suffered extensive damage with its garage and porch destroyed. Damage from the first home impacted a second home, also causing extensive damage to the west side of the house. This damage was consistent with an F2 tornado. As the tornado lifted out of the valley, it quickly dissipated. The tornado was on the ground for 3 miles in Miami county with a total track of 4 miles during its lifetime. No injuries were reported as one house was unoccupied and the residents of the other house, had sought shelter in their basement.

 Brief Description: EVENT NARRATIVE: The tornado that entered this county exited the Grissom Air Reserve base on the Cass/Miami county line and continued east-southeast, crossing a small area of trees where signs of slight debarking was noted (DI: TH DOD: 5). The tornado continued on along to the 3000 block of County Road 900 South where the most substantial damage occurred to a one and one half story home. Only a few kitchen walls remains of the structure (DI: FR12, DOD 8) with one resident in the kitchen and one in the basement. Two other residences suffered extensive damage but remained intact. The tornado crossed US 31 and continued for a few more miles, causing some additional tree and structure damage including several buildings at a hog farm being destroyed. The tornado eventually dissipated east of Strawpike Road, north of East 1000 South in a field. A local newspaper article reported that a check that was originally located at the destroyed home, was found nearly 50 miles away in Wells county in perfect condition. Total damage along the track of the tornado is estimated at $750,000. EPISODE NARRATIVE: A supercell developed ahead of a cold front in Illinois and tracked east-southeast through Benton county into White county. This storm produced three tornadoes across Indiana, an EF0 in eastern White county (which moved into Carroll county), an EF1 which started in eastern Carroll county and moved into Cass county, and a third, a stronger EF3 which formed near the Grissom Air Force base in Cass county and moved rapidly east into Miami county. Despite the tornadoes occurring during the overnight hours, no fatalities occurred.

 Brief Description: A NWS survey confirmed a tornado touched down a few hundred feet west of county road 950 E between 500 and 600 S, just southwest of Onward. Extensive damage occurred to a barn as well as numerous trees in the area. The door of the barn was open which likely aided in the destruction of the barn. Damage in the area was consistent with a tornado of F2 intensity. The tornado continued on into Miami county where additional damage was found.

 Brief Description: EVENT NARRATIVE: After a brief break, the supercell produced one more circulation which touched down just west of the Cass/Miami county line along South County Road 1000 East. Several yards in the area had trees uprooted and limbs down (DI: TH, DOD: 4). A few residences were impacted by the trees, causing mainly roof or window damage . The circulation then went into a dense grove of trees with the circulation briefly weakening before coming back out near the Grissom Air Reserve Base. A 200 foot section of security fence on the southwest corner of the base was blown down into the adjacent roadway and portions of the nearby field before crossing into Miami county. An Automated Weather Observation System recorded a 114 mph wind gust as the circulation passed through. EPISODE NARRATIVE: A supercell developed ahead of a cold front in Illinois and tracked east-southeast through Benton county into White county. This storm produced three tornadoes across Indiana, an EF0 in eastern White county (which moved into Carroll county), an EF1 which started in eastern Carroll county and moved into Cass county, and a third, a stronger EF3 which formed near the Grissom Air Force base in Cass county and moved rapidly east into Miami county.

 Brief Description: This strong tornado originated from a supercell which initially produced several funnel clouds beginning northeast of Crawfordsville, passing over Frankfort to Kokomo's south side. This supercell finally produced its tornado just south of Kokomo near Oakford and Center. The tornado damaged a school near Center and caused its most extensive damage in Greentown where over two dozen buildings were destroyed and nearly 200 buildings were damaged. The tornado continued tracking ENE along the N & W train tracks and into WC Grant County west of Swayzee.

 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.

 Brief Description: EVENT NARRATIVE: The tornado touched down near the intersection of 12B and Gumwood Roads, just west of Bourbon. Initial damage comprised of damage to shingles on a few roofs as well as some tree damage. As the tornado moved northeast and intensified it blew down a 3/8 mile long stretch of power poles. A total of 16 homes suffered damage from the tornado, 3 were destroyed, 1 suffered major damage and 12 suffered minor damage. Some barns, storage sheds, silos and garages suffered damage of varying degrees as well. The tornado reached the higher end of EF2 as it entered into Kosciusko County. A Bourbon Fire Department grass truck crashed into a ditch during the storm, with the driver being taken to the hospital for unknown injuries. It is not known as to why the crash occurred. 3 other non-specific minor injuries were reported. Damage is estimated at around $600,000. EPISODE NARRATIVE: A combination of strong dynamics, wind shear, and rapid low level moisture return all combined to produce severe weather across much of Northern Indiana. One of several supercell thunderstorms produced a long tracked tornado which reached the high end of EF3.

 Brief Description: EVENT NARRATIVE: The tornado continued northeast out of Kosciusko County into the southeast side of Nappanee where the most extensive damage occurred. The width of the tornado decreased to one quarter mile and intensified just south of US-6 and County Road 7 as wind speeds increased to around 165 mph, in the upper range of the EF3 rating. The tornado went through an area populated by homes, restaurants, convenience stores and 3 RV plants, all of which sustained varying degrees of damage. Local officials reported that 459 buildings were damaged. Of these, 352 were homes with 52 of those being destroyed or uninhabitable. 81 businesses were damaged and 26 destroyed. A few minor injuries were also reported, mainly from people trapped in some of the houses and a few businesses. The tornado continued into the Blackstone subdivision where numerous homes were damaged or destroyed. The tornado continued to west of New Paris near the intersection of County Roads 46 and 17 where it lifted. Numerous vehicles of all varieties sustained severe damage. Damage is estimated around $11 million. EPISODE NARRATIVE: A combination of strong dynamics, wind shear, and rapid low level moisture return all combined to produce severe weather across much of Northern Indiana. One of several supercell thunderstorms produced a long tracked tornado which reached the high end of EF3.

 Brief Description: EVENT NARRATIVE: This tornado touched down at 7:25 P.M. EDT, as reported by trained spotters, about 3 miles east of Arcadia . The tornado continued a path to the northeast, lifting around 7:30 P.M. EDT. An EF2 rating was assigned to this tornado given the significant destruction of a barn, and the tornado moving a dual wheel pickup truck/trailer rig nearly fifteen feet. Winds were estimated near 120 mph. Several other outbuildings, houses, barns, vehicles, trees, sheds, and garages suffered damage as well. EPISODE NARRATIVE: Severe thunderstorms moved through central Indiana on the afternoon of 11 April 2007. The storms produced tornadoes, large hail, and damaging winds. The National Weather Service Indianapolis damage assessment teams confirmed four tornadoes in central Indiana. These tornadoes occurred from mini supercells.

 Brief Description: 4 TRAILER HOMES DESTROYED, SEVERAL OTHERS SUFFERED MINOR TO MAJOR DAMAGE, ONE HOME AND BARN DESTROYED, SEVERAL OTHER HOMES SUFFERED MODERATE DAMAGE. TORNADO STARTED IN RIPLEY AND TRACKED EAST NORTHEAST TO MONTEREY BEFORE IT LIFTED. EXTENSIVE TREE DAMAGE OCCURRED ALONG THE TORNADOES PATH. Synoptic and mesoscale conditions for June 11, 1998... Morning sfc and upper air analysis revealed a potent upper short wave trough across North Dakota with an intensifying area of sfc low pressure across southwest Kansas. An unseasonably strong 140 knot jet streak was ejecting out of this trough across Kansas with the left front exit region progged into central Indiana after 18Z. Increasing moisture convergence and theta-e advection along the northward lifting warmfront was seen as 850 mb winds were forecast to increase to 55 knots. By 21Z, the sfc low had moved into eastern Iowa and deepened to 994 mb. The prestorm enviornment was characterized by moderate to extreme instability (LI values -7 to -9 and CAPE values in excess of 2000 J/kg) with temperatures in the lower 80s and dewpoints in the low/mid 70s. This combined with a dry punch at 700mb and deep layer shear along the warm front, where storm relative helicity values increased to 400 M2/S2, lay the foundation for an outbreak of damaging tornadoes across Indiana.

 Brief Description: The tornado touched down on CR 64, one half mile west of Indian Springs Camp Ground. Trees and power lines were knocked down and many were snapped and uprooted. Extensive roof damage occurred to houses in the area. A barn was damaged with much of its roof torn off and outbuildings were either damaged or destroyed. The tornado then lifted back into its parent cloud. Synoptic and mesoscale conditions for June 14th... A significant mid-level shortwave trough was located over Iowa on the morning of June 14th with an outflow dominated squall line across western Illinois. Rapid destabilization ensued later in the morning across eastern Illinois and northern Indiana with CAPES to 3500 j/kg by early afternoon. VAD wind profiles showed 850 millibar winds in excess of 50 knots in advance of the upper trough by afternoon and as storms developed along the left over outflow boundary across Illinois... they quickly became severe and organized into a large bow echo and moved quickly eastward into northern Indiana causing extensive wind damage. By late afternoon... a short segmented squall line developed just ahead of this bow echo squall line and extended from a St. Joseph to Fulton county line. Along the southern end of this line... an embedded tornadic supercell developed and interacted with a left over storm-scale outflow boundary to produce the Wabash/Kosciusko and DeKalb county tornadoes. The lack of significant low level shear likely prevented a much larger and more widespread tornado event especially across Whitley and Allen counties where several funnel clouds were captured on film but failed to touch down.
