Ranked by deaths, injuries, damage and size together.
- Tornadoes and Hail in Wisconsin, August 18, 2005The largest single-day tornado outbreak in Wisconsin recorded history for south-central and southeast Wisconsin occurred on August 18, 2005. Sixteen tornadoes were documented on this day in south-central and southeast Wisconsin, a new single-day record.
- Tornadoes and Hail in Wisconsin, June 23, 2004Two rounds of severe weather affected parts of south-central and southeast Wisconsin on June 23rd, with the second round featuring 8 tornadoes, large hail (up to golf-ball size), and powerful straight-line downburst winds.
- Tornadoes and Hail in Wisconsin, January 7, 2008Very rare, mid-winter, severe storms affected parts of south-central and southeast Wisconsin on January 7th - in the form of two tornadoes and scattered, large, hailstones, and downburst winds.
- Tornadoes and Hail in Wisconsin, April 10, 2011Thunderstorms developed along and ahead of a cold front as it encountered moist and unstable air across Wisconsin. A record number of tornadoes for April struck Wisconsin on April 10.
- Tornadoes and Flash Flooding in Wisconsin, June 12 to 13, 2008A series of clusters of strong to severe storms ahead of a cold front moved east/northeast across south-central and sourtheast Wisconsin. Copious amounts of moisture were available that allowed repeated heavy rains.
- Tornadoes and Hail in Wisconsin, June 21, 2010Strong to severe thunderstorms developed across much of south central and southeast Wisconsin during the evening of June 21, 2010. A vigorous upper level disturbance helped to support deep vertical motions in the atmosphere, along with strong deep layer wind shear.
- Tornadoes and Flash Flooding in Wisconsin, June 7 to 8, 2008A slow-moving surface boundary, nearly parallel with the mid-level flow affected southern Wisconsin during the period of June 7th through June 9th.
- Tornadoes and Flash Flooding in Wisconsin, April 14, 2026Numerous severe thunderstorms developed across southern Wisconsin during the afternoon and evening hours as a wave of low pressure moved across a stationary front over the region.
- Tornadoes and Flash Flooding in Wisconsin, June 1, 2000One would be hard pressed to find another day like June 1, 2000 in terms of depth and range of severe, convective weather events across south-central and southeast Wisconsin.
- Tornado and Hail in Wisconsin, March 8, 2000After several days of record-breaking warmth, the stage was set for an out-of-season severe weather outbreak across southcentral and southeast Wisconsin.
- Tornadoes and Hail in Wisconsin, May 30, 1998Trees and power lines down.
- Tornadoes and Hail in Wisconsin, June 23, 2004A line of thunderstorms that moved out of Minnesota produced wind damage, hail and several tornadoes. The first tornado touched down about 1.5 miles north of Taylor (Jackson County) around 6:22 p.m.
- Tornadoes and Hail in Wisconsin, May 22, 2011During the afternoon of May 22nd, severe thunderstorms developed along a cold front as it moved through western Wisconsin. These severe thunderstorms produced three confirmed tornadoes, two of which were rated as EF2 with the other being an EF1.
- Tornadoes and Flooding in Wisconsin, April 10 to 14, 2011A cold front pushed east into Wisconsin during the late afternoon and evening hours of April 10th. Severe thunderstorms developed along the cold front and produced very large hail and three tornadoes over portions of western and central Wisconsin.
- Tornadoes and Hail in Wisconsin, July 14, 2010The morning of Wednesday July 14th had a complex of severe thunderstorms moving across eastern North Dakota, into portions of west-central and central Minnesota.
- Tornado and Flash Flooding in Wisconsin, April 15 to 16, 2026An organized area of low pressure tracked along a stationary over the region and brought lines and clusters of strong thunderstorms and heavy rainfall to southern WI. Flash flooding occurred in spots from Rock County to the Milwaukee area.
- Hail and Damaging Winds in Wisconsin, August 21, 2013A broken line of severe storms developed in an unstable air mass ahead of an advancing cold front. The storms produced large hail and damaging wind gusts, at times in excess of 70 mph.
- Tornadoes and Hail in Wisconsin, June 15, 2022Two rounds of storms moved across western Wisconsin during the late morning and afternoon of June 15th. The morning storms produced some hail and wind damage. Quarter sized hail fell in Stoddard (Vernon County) and trees were blown down southeast of La Crosse (La Crosse County).
- Tornado and Hail in Wisconsin, June 25, 1998Severe thunderstorms packing winds between 60 and 70 mph and producing hail between 1 and 2 inches in diameter caused significant damage to property and crops.
- Tornadoes and Hail in Wisconsin, July 6, 2003Two rounds of scattered severe convection affected south-central and southeast Wisconsin on Sunday, July 6, 2003. The first round occurred during the morning hours and the second during the late afternoon hours.
- Tornadoes and Hail in Wisconsin, May 22, 2011Severe thunderstorms produced high winds, large hail, and a tornado across central and northeast Wisconsin on May 22, 2011. Unstable air combined with a surface boundary and an upper air disturbance to produce thunderstorms.
- Tornado and Flooding in Wisconsin, August 21 to 22, 2002The severer weather and flooding that affected much of south-central and southeast Wisconsin on August 21, 2002, into the pre-dawn hours of the 22nd, was probably the most widespread and significant outbreak for the 2002 warm-season.
- Tornadoes and Damaging Winds in Wisconsin, July 22, 2010A stalled frontal boundary combined with a moist and unstable atmosphere and strong wind shear to produce numerous tornadoes and funnel clouds over South Central and Southeast Wisconsin.
- Tornadoes and Hail in Wisconsin, June 6, 1999A significant change in the upper level pattern to a more southwesterly flow allowed tropical-like moisture to return to southern Wisconsin in conjunction with an upper level shortwave trough.
- Tornado and Flood in Wisconsin, July 18, 1997Lightning struck a car on I-43, disabling vehicle completely.
