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

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
Severe thunderstorms affected much of northern, central and east-central Wisconsin during the afternoon and evening of July 16 with tornadoes, downburst winds and large hail. Millions of dollars in damage resulted from the biggest severe weather outbreak to affect the region in years.The storms began to develop early in the afternoon across north-central Wisconsin. Hail the size of baseballs fell in Minocqua (Oneida co.), damaging nearly 200 vehicles. As those storms moved southeast and weakened, a new supercell thunderstorm developed over Lincoln county. This new storm produced wind damage in Tomahawk and softball size hail northeast of Merrill. About 20 minutes later, a tornado…
- Jul 30, 2002Thunderstorm Wind$100,000
National Weather Service narrative
Thunderstorms moved through Wisconsin in very warm and unstable air ahead of a cold front. Severe thunderstorm winds and tornadoes downed trees and power lines and damaged buildings across a large swath of central, north central and east central Wisconsin. Thousands of trees and power lines were downed by high winds from the storms. An 11 year old Boy Scout was killed and another was seriously injured when trees landed on their tent at Camp Napowan (Waushara co.).High winds pushed a house off its foundation and blew a boat and trailer into a neighbor's yard near Merrill (Lincoln co.). Some downed trees damaged or destroyed buildings or vehicles when they fell. A church steeple was…

- Jun 14, 2017Tornado$75,000
National Weather Service narrative
An EF1 tornado formed and moved north-northeast on the west side of the city of Pulaski. The tornado ripped off a garage door and one side of the garage collapsed inward (DI 2, DOD 4). Another nearby garage door (on a different property) collapsed and one side was heavily damaged (DI 2, DOD 4). In addition, a barn's roof was collapsed (DI 1, DOD 5). Several dozen trees were uprooted in wet soil or heavily damaged (DI 27 and 28, DOD 2 and 3) in the path of the tornado.
- Jul 20, 2010Thunderstorm Wind$50,000
National Weather Service narrative
Thunderstorm winds downed or snapped numerous trees and downed power lines throughout Wittenburg. The Wittenberg-Birnamwood High School had about 75 feet of its rubber membrane roof and underlying foam insulation peeled from the west side of the gymnasium. Several large pine trees along the south side of the school were uprooted. A camper trailer was blown from its support pad and rolled about 40 feet before resting on its roof. Two of the three pools at the water treatment plant had portions of their plastic thermal covers blown off. Downed trees blocked State Highway 45 causing authorities to close the road for several hours. More than 140 homes were damaged, but damage to most…
- Aug 28, 2003Thunderstorm Wind$50,000

- Jul 14, 2010Thunderstorm Wind$35,000
National Weather Service narrative
Thunderstorm winds downed trees at numerous locations across western Shawano County. The most concentrated damage was about 3 miles northwest of Bowler where estimated wind gusts of 85 to 95 mph from a microburst caused significant damage. A stand of pine trees 200 yards wide by 400 yards long was almost completely flattened with several trees snapped about 10 to 15 feet above the ground. A home and work shed were damaged by fallen trees and a truck was crushed. About a mile to the east a barn and outbuilding were flattened by the wind.
