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

When the rain finally stopped, total rainfall amounts of 10 to 12 inches was reported from the extreme eastern parts of Niles into Edwardsburg. Numerous roads remained closed with some culverts and bridges suffering damage. No injuries were reported. No exact figures are available for the damage to the area from the flooding.

An area of scattered damage originated at the Dowagiac airport, with a hangar suffering moderate damage. The wind damage continued to expand with the roof being shifted off a business in the 54000 block of M-51. The remainder of the damage was confined to numerous three to four foot diameter trees being uprooted or snapped, as well as some large branches down. A few of these did fall on a few structure but damage was very limited. Damage for the area is estimated at $400,000.

National Weather Service narrative
More than six dozen large trees were uprooted with hundreds of other trees either split or missing large limbs after a severe thunderstorm with estimated 70 mph winds blew through the Edwardsburg area around 7:50 AM EDT Wednesday, July 2, 1997. Downed trees and utility poles limited travel by blocking at least 6 area roads and road crews worked through the day to clear debris. Almost all of the village's 1,200 residents were without power for most of the day. The hardest hit area of Pleasant Lake reported 16 large trees uprooted. On the south side of the lake along Washington Street, one home was destroyed. Trees were downed onto several houses. The Ontwa Township/Edwardsburg…

National Weather Service narrative
Microburst damage continued into Cass County from Berrien County, near County Line Road and Frost Street. Tree damaged continued along the track, with somewhat more concentrated damage towards the end of the path as it tracked across some residential areas. Three homes suffered minor damage from either the winds or trees falling onto them. A barn and garage were destroyed at the end of the microburst near Wilbur Hill Road and Peavine Street. The supercell that caused the microburst produced yet another tornado just to the east of this microburst damage.

National Weather Service narrative
After leaving behind a swath of microburst winds, the storm intensified with a tornado touching down about a half mile southwest of Southwestern Michigan College, near Dowagiac. The circulation initially impacted the Pokagon subdivision with numerous homes suffering varying degrees of damage (DI: FR12 DOD: 4). The circulation continued east-southeast through mainly open and wooded areas, severely damaging numerous trees. The most extensive tree damage occurred near Michigan 62, west of Twin Lake Road where a 600 yard wide area of trees suffered extensive damage. The circulation was likely embedded within a much larger area of rear flank downdraft winds. The circulation then turned…
