Waushara County

Every recorded tornado

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

1. May 12, 2000Hail$26.0 million
   National Weather Service narrative

   During the mid and late morning of May 12, a high precipitation supercell thunderstorm developed in west-central Wisconsin and tracked east across the state for over two and a half hours. The storm produced a prolific path of large hail, a brief tornado, and a significant wet microburst across central and east central Wisconsin. The storm was one of the most damaging thunderstorms in Wisconsin history, producing well over $100 million in damage.The thunderstorm developed north of a warm front, which was located across the Wisconsin/Illinois border. The setup was favorable for what is known as "elevated" convection; that is, the source of the instability was aloft, and not…

2. Jun 11, 2001Thunderstorm Wind$5.0 million
   National Weather Service narrative

   During the late evening of June 11th a large thunderstorm complex, including a bow echo, moved across central and east central Wisconsin. Winds exceeded 70 mph across the area, resulting in thousands of downed trees and damage to homes and businesses. What made the storm particularly significant was the sustained strong winds causing more damage than typically experienced with a single severe wind gust. In Oshkosh, winds of 45 to 70+ mph were recorded for 45 minutes, veering from west to north during that span. The high winds and rough water knocked over dozens of sailboats on Lake Winnebago, sinking at least one. The storms knocked out power to at least 100,000 customers. The…

6. Nov 10, 1998High Wind, Waushara$200,000
   National Weather Service narrative

   An intense area of low pressure moved across the Midwest on November 10, producing very high winds, rain and snow across the region. The low, which tracked from central Iowa to western Lake Superior, resulted in record minimum pressures in Iowa and Minnesota and an unusually widespread high wind event across Wisconsin. The strong winds lasted for much of the day.The high winds caused one fatality and an injury in the area, both in Door county. A 67 year old Door county woman died a week after being blown down by a strong gust of wind. Her head hit the concrete ground, causing the fatal injury.Trees, street signs and power poles were damaged or destroyed by the strong winds across…
