  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Greene County: 37.
  2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

  1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

The tornado continued to move east across western and central Greene County before lifting along U.S. 68, about 5 miles north of Xenia.||There were two locations along the track of this tornado in the Beavercreek area where damage was indicative of EF3 intensity. The first was in the vicinity of I-675 and Grange Hall Road. Several homes along Rushton Drive had entire roofs lifted, as well as the collapse of several exterior walls with only interior walls left standing. Additional homes along Gardenview and Wendover Drives experienced…

    A violent tornado that moved at 65 mph hit the town of Xenia for the second time in 26 years damaging some of the same areas that were hit in 1974. Along the path of the tornado, around 250 homes were either damaged or destroyed, over 40 businesses were damaged or destroyed including the local Wal Mart, Kroger, and Tire Discounters, and 6 churches were damaged. A strip mall was nearly destroyed, cars were thrown from the Highway 35 bypass into ditches, 4 semi-trailers were thrown up to 400 yards, and most of the buildings were damaged or destroyed at the Greene county fairgrounds. In Sugarcreek Township, which is to the southwest of Xenia, an additional 14 houses and 3 barns were…

    The tornado initially touched down at the Greene Crossing Shopping Center on Indian Ripple Road. At least 5 cars were lifted and rolled, with 2 injuries occurring in 2 of the vehicles that were rolled. As many as 22 cars in the parking lot at Greene Crossing Shopping Center were damaged with most of the damage being blown out windows.||Additional roof, window and awning damage occurred to a restaurant building as well as to the strip mall within the shopping center. The most significant damage was shattered windows and a partial collapse of a brick roof facade at Fitworks, along with a rooftop HVAC unit being pushed off of the roof. The damage was consistent with 100 to 105 mph…

  5. Apr 3, 2018Tornado$500,000
    National Weather Service narrative

    The tornado first touched down in the 1000 block of Ludlow Road in Beavercreek Township. One barn on the property had roof damage, while the other barn had wall damage. In addition, a silo collapsed. Numerous hardwood and softwood trees were damaged and there was roof and chimney damage to the home. This damage was consistent with low end EF1/high end EF0 damage, with wind estimated at 85 to 90 mph.||Several properties further east along Ludlow Road sustained damage. The most significant being in the 800 block, where a home sustained more than 30 percent of its roof torn off, multiple broken windows, and structural damage to both the exterior and interior walls of the home. Damage…

    The tornado initially touched down in a field just west of Stringtown Road, where minor tree damage occurred. Damage in this area was consistent with wind speeds around 75 miles per hour. The tornado continued across Highway 35 and Federal Road, where a farmstead was struck. A barn at this location sustained heavy damage, with much of the roof being removed as well as some wall failure. Wind speeds at this location were estimated to be around 85 miles per hour. |The tornado then crossed Highway 72 and damaged a property heavily. At this location, several fences and outbuildings were completely destroyed. The residential home had windows blown out and significant roof damage. Roof…

    The tornado initially touched down at 0437EST in far northeast Montgomery County, near the intersection of Mitchell Drive and Spinning Road. The tornado moved quickly east-northeast and entered Greene County, just past Airway Road as it moved into the far southern portions of Wright-Patterson Air Force Base at 0438EST. ||A restoration hangar at Wright-Patterson Air Force Base received minor structural damage with sheet metal ripped off. Some planes that were in the process of being restored also suffered damage due to flying debris. This damage was notable enough to warrant EF1 strength winds of around 100 mph. Additional damage occurred along Loop Road, where guard rails were…

  8. Jan 6, 1996Winter Storm, Greene$500,000
    National Weather Service narrative

    The Blizzard of '96 developed near the Gulf Coast and moved up the East Coast. This massive system produced the greatest total and 24 hour snowfall at Greater Cincinnati\Northern Kentucky airport. This one storm brought 14.3 inches of snowfall to the airport which normally receives 23 inches for an entire season. The heaviest snow fell near the Ohio river in the extreme south. The worst blizzard conditions occurred over West Central areas as dry and powdery snow was blown around by high winds causing whiteouts. Some areas had more than 30 continuous hours of snowfall, and many people in Southern Ohio felt this was the worst winter storm since the Blizzard of '78. In Fayette…

    The beginning of this tornado is believed to have occurred along South Charleston Road where homes on both sides of the road had multiple large hardwood trees snapped. One residence also had a shed completely destroyed and metal from the shed was blown into the field.||On the next road east across the field, on Rogers Road, the most significant damage from the tornado was observed. The second story of one home had much of its roof removed and had multiple interior walls collapsed. Tree damage was also significant at this property as well as at nearby residences on Rogers Road.||Further east, at a property along Watkins Road, a roof was ripped off of a barn, with a shed completely…
