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

- Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

- 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
Heavy rainfall caused record flooding on the Embarras River at Lawrenceville. The river reached a level of 42.3 feet at 2325 CST on 6/9. This resulted in the breach of at least 4 levees on the Embarras and Wabash Rivers which produced widespread flooding in eastern Lawrence County. In the town of Lawrenceville, 158 homes had water in the first floor living area, while 48 others reported water in the basement. In addition, 8 businesses had in excess of 5 feet of water. Lawrence County was declared a disaster area due to the flooding.

Numerous grain bins, machine sheds and pole barns were severely damaged as well. In addition, one home experienced moderate damage. One man sustained minor injuries from flying debris.
- May 8, 1996Flash Flood$250,000

One woman had to be rescued when the car she was trying to move out of harms way was pushed down stream from her home. The car hit a bridge abutment and she had to be pulled out of the passengers' side window. No injuries were reported, but property damage was extensive. There was $250,000 in road and bridge damage, though no estimate of private property damage was available yet.
