Hardin County

Every recorded tornado

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

Smoke overhead

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.

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.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
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).

Several wooden power poles were damaged and snapped in half. On the northern side of the fairgrounds, a hardwood tree was snapped and a building sustained a major loss of its metal roofing panels. An additional building had its concrete block siding blown out, which caused a partial roof collapse. An open-ended barn structure was lifted, causing the support poles to be lifted and shifted.

7. Jan 2, 1996Winter Storm, Hardin$50,000
   National Weather Service narrative

   Low pressure strengthening in the Tennessee valley passed southeast of Ohio. The heaviest snow fell near and north of interstate 70, across West Central Ohio where there was up to 1 foot of snowfall and blizzard conditions. Wind gusts up to 40 mph were common in this area with snow drifts between 3 and 5 feet. Across parts of Southern Ohio there was a messy mix of precipitation. Roads oriented east to west were quite hazardous as strong north winds produced large snow drifts shortly after these roads were plowed. Temperatures during much of this event were in the upper teens and 20s.
