1,435 first-hand accounts of flood events in Wisconsin, ranked by impact. Each is a NOAA-written narrative of the moment.
A warm front across Wisconsin lifted north during the afternoon and evening. Moist and very unstable air south of the front led to the development of severe thunderstorms.

Read the full account →A line of intense thunderstorms swept in from Minnesota and caused widespread straight-line wind damage to many areas of central and western Wisconsin. This was one of the worst storms to hit the region in over 25 years.
Read the full account →An isolated cluster of severe thunderstorms developed north of the Madison area (Dane Co.) and proceeded to move southeast at about 15 mph. The storms produced wet microbursts that levelled trees and stop signs on the southside of Madison.

Read the full account →Clusters of severe thunderstorms moved southeast through south-central and southeast Wisconsin, resulting in damaging straight line winds that toppled large trees, very large damaging hail, and heavy rains that led to flash flooding.
Read the full account →A stationary front set up across central Wisconsin on the evening of September 22nd. As an unusually moist air mass flowed over this boundary, heavy rain developed and fell repeatedly across the area during the evening and overnight hours.
Read the full account →Flooding continued to affect areas along rain-swollen rivers and streams, which had been deluged by excessive rainfall amounts of 3 to 6 inches.
Read the full account →Another complex of thunderstorms developed the night of the 8th into the 9th across the Northern Plains and pushed eastward across the Northland during the morning hours.
Read the full account →A surge of warm and moist air on a low level jet stream resulted in numerous thunderstorms over southern Wisconsin. Very heavy rain resulted in flash flooding, some street flooding; in addition to some hail with the storms.
Read the full account →Excessive thunderstorm rains produced flash flooding and relatively rapid rises on the larger tributaries in west and southwest Wisconsin. There was at least two feet of water over some roadways across southern Clark County and northern Jackson County, along with flash flooding…

Read the full account →Rapid snowmelt of a deep and wet snowpack, along with some rain, resulted in rising water levels in many of the larger rivers in south-central and southeast Wisconsin during the period of March 11th through March 19th.
Read the full account →Deep layer shear with a short wave trough interacted with instability ahead of a surface trough trailing from a surface low in central Wisconsin. The instability and shear produced supercell thunderstorms in southern Wisconsin along and ahead of the surface trough.
