  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Preble County: 0.
  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.

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

  2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

    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 most significant structural damage at this location was the complete removal of the west-facing portion of the roof over the smaller section of the house. There was also significant damage to siding on the east-facing side of the same house,…

    National Weather Service narrative

    The first sign of tornadic damage appeared near the intersection of Hawley Mills Road and New Paris Twins Road, where uprooted trees and a significant loss of roof panels from a barn occurred. The tornado continued to uproot trees off of New Paris Twins Road and caused some walls of an older barn building to collapse before traveling further northeastward through some open fields.||The next points of damage were observed near the intersection of New Paris Twins Road and Rawley Road.

A section of wood and metal roofing material measuring approximately 55 feet by 15 feet was lifted from the northeast side of a barn and strewn for approximately 100 feet to the northeast, and a lesser distance to the northwest. A utility pole was also snapped at this location. Eyewitness accounts from the residents indicated the damage resulted from a visible circulation that passed through the property. The residents also pointed out a section of metal roofing material from this location that was carried…
