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

- 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.

- 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.

- 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).
- 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
A major winter storm dumped 6 to 10 inches of sleet and snow north and west of Evansville, including Pike County. In addition to the sleet and snow, up to one-half inch of ice coated objects. This resulted in very difficult driving conditions. Numerous vehicles slid off roadways. Schools were out for several days. Isolated power outages affected a small number of people north and west of Evansville. From Evansville south and east, a major ice storm occurred. About one inch of ice accumulated. This resulted in widespread tree damage and numerous power outages. In the city of Evansville itself, several inches of sleet and snow were combined with nearly an inch of ice. The weight of…
- Sep 14, 2008High Wind, Spencer$4.0 million
National Weather Service narrative
Frequent wind gusts from 50 to 70 mph caused numerous problems in southwest Indiana. The low pressure center that was the remnant of Hurricane Ike raced northeast at 40 to 50 mph across Missouri and Illinois. The center passed between Carbondale, IL and St. Louis, MO on its way toward the northeastern states. The rapid speed of the low pressure system contributed to this high wind event. A peak wind gust of 64 mph was measured by the automated observing system at the Evansville airport. The highest sustained wind at the airport was 47 mph. An unofficial wind gust of 66 mph was measured at Newburgh.||Extensive tree damage occurred. Trees were uprooted and very large limbs were…

- Jan 5, 2025Winter Storm, Spencer$125,000
National Weather Service narrative
A major winter storm impacted southwest Indiana on the 5th with a mix of snow, sleet, and freezing rain. Heavy snow with rates around 1 inch per hour impacted locations along and north of Interstate 64 beginning in the morning hours before eventually ending as sleet and freezing rain later that day. A lull occurred that evening with areas of freezing drizzle before wrap around moisture caused one final burst of snow into the morning hours on the 6th. Peak accumulations ranged from 4 to 8 inches of snow and sleet along with glazes of ice. Further south along an axis that extended along the Ohio River, a period of snow on the onset transitioned to sleet and freezing rain, ending as…
