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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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.

  2. 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).

Costliest events since 1996

  1. Apr 14, 2002Flood, Ashland$189,000
    National Weather Service narrative

    Dense snowpack, temperatures in the 80s, and heavy rain contributed to widespread flooding in central and southern Ashland County. Both the Bad and Chippewa Rivers flooded, closing roads in Mellin and Glidden. In Glidden, 20 homes and businesses were damaged by floodwaters of the north fork of the Chippewa River. A 100-yard stretch of Highway 13 was closed due to high water. Highway 169 between Mellin and U.S. Highway 2 was closed. Other small streams and creeks overflowed their banks and caused minor lowland flooding.

  2. Jun 6, 1999Thunderstorm Wind$150,000
    National Weather Service narrative

    Severe thunderstorm winds caused extensive damage at the Ashland county fairgrounds. A cow barn was destroyed and the grandstand was severely damaged. Some debris was blown 300 feet. Many trees were blown down. Half of a double-wide modular home was overturned elsewhere in Marengo. The wind speed was estimated based on the amount of damage.

  3. Jul 1, 2011Lightning$80,000
    National Weather Service narrative

    A home sustained an estimated $80,000 worth of damage after lightning struck it, causing a fire. Lightning struck a gas meter located on the side of the house, igniting natural gas.

  4. Jul 1, 2011Thunderstorm Wind$50,000
    National Weather Service narrative

    The winds blew down numerous trees. Several homes were damaged from falling trees. There was also some structural damage at the Ashland County fairgrounds.

  5. May 22, 2011Thunderstorm Wind$10,000
    National Weather Service narrative

    There was minor siding damage to a home, a metal barn collapsed, and some trees were blown down along Balsam Lane to the east-southeast of Butternut. The metal barn probably collapsed at a lower wind speed than would normally be expected, given a lack of damage to nearby pine trees. Estimated wind gusts in this area were around 80 mph.

  6. Oct 26, 2010Strong Wind, Ashland$5,000
    National Weather Service narrative

    The strong wind gusts caused scattered power outages county-wide. According to the sheriffs department, the most heavily affected areas in the county were in the towns of Chippewa and Jacobs. Lots of trees were blown down, along with trees blown onto power lines. Some damage was also reported on Madeline Island.

  7. Aug 13, 2010Thunderstorm Wind$3,000
    National Weather Service narrative

    Severe thunderstorms blew through northwest and north-central Wisconsin...producing damaging winds and some hail.

  8. Jul 14, 2010Thunderstorm Wind$2,000
    National Weather Service narrative

    Power lines were reported down along U.S. Highway 13.

  9. May 9, 2011High Wind, Ashland$2,000
    National Weather Service narrative

    Strong winds uprooted trees, blew down some tree limbs and tree branches, and brought down a few power lines. This sporadic damage was confirmed from spotter and public reports, as well as local newspaper articles. The strong winds uprooted large pine trees at the Mellen Union Cemetery, and the root structures overturned some grave stones. Amateur radio reported a satellite dish and a few shingles blown off a house around Mellen. Wind gusts at individual stations were measured at 43 mph in High Bridge, and 46 mph in Glidden. However, damage suggests that isolated areas probably received wind gusts up to 60 knots (69 mph).

  10. Apr 10, 2011Hail$1,500
    National Weather Service narrative

    Oblong and spiky hail stones up to 3 inches in diameter fell near the town of Odanah.

  1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
