1,435 first-hand accounts of flood events in Wisconsin, ranked by impact. Each is a NOAA-written narrative of the moment.
A convective thunderstorm complex that orginated over southern Minnesota moved east/southeast across southern Wisconsin and generated a line of strong to severe storms.
Read the full account →Two rounds of severe weather affected south-central and southeast Wisconsin on July 10th. An initial cluster of storms north of the Milwaukee area in Ozaukee County pulsed to severe limits and generated large hail up to 3/4 inch in diameter during the early afternoon hours.
Read the full account →The first widespread severe weather outbreak to affect south-central and southeast Wisconsin occurred on April 25th. It consisted of mostly large hail up to 1.25 inches in diameter, a couple damaging, straight-line wind reports, two tornadoes in Columbia County, and scattered…

Read the full account →Three rounds of thunderstorms produced wind damage and flash flooding during the afternoon, evening, and overnight hours of August 9th. The thunderstorms developed as a cold front trailing from low pressure over northeast Wisconsin moved into a hot, humid and unstable air mass…
Read the full account →A line of severe thunderstorms moved out of Minnesota and into western and central Wisconsin during the morning hours of August 13th. Strong winds created tree and minor structural damage, while widespread heavy rain of 3 to 4 inches caused some flash flooding, road closures,…
Read the full account →A continuous feed of moisture, in a low to mid-level warm air advection regime, impinged along an outflow boundary draped across southern Wisconsin.
Read the full account →A cold front tracked west to east across western and central Wisconsin during the afternoon and evening hours of July 14th. Severe thunderstorms developed along the cold front and produced severe wind gusts, funnel clouds, large hail and one tornado.

Read the full account →Repeated rounds of thunderstorms with heavy rain caused flash flooding in Sauk and Columbia counties. The thunderstorms developed ahead of a warm front, as a low-level jet pushed warm, moist air over the boundary.
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 →A strong and slow moving area of low pressure moved from the Central Plains on the 12th to over Minnesota on the morning of the 14th and became occluded. A cold front pushed across northwest Wisconsin on the 13th with heavy rainfall being received in some locations.
Read the full account →A stationary frontal boundary across central Minnesota, and an increasing very moist airmass with PWATs near 1.75 early Friday morning, July 15th, was the setup for a flash flood event over Chippewa County Wisconsin.
Read the full account →Flooding took place along the Pecatonica River in and near Martintown (Green county) due to the combination of .50 to 1.00 inch of rain, rapidly melting snow, and a nearly frozen ground. Ice action and minor ice jamming complicated and enhanced some of the flooding.
Read the full account →A series of showers and thunderstorms dumped heavy rains and small hail (1/4 to 1/2 inch in diameter) on already saturated soils over southcentral, southeast, and eastcentral Wisconsin, resulting in scattered reports of urban and small stream flooding.
Read the full account →One 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.
Read the full account →Heavy rains, in some cases, setting new daily records across south-central and southeast Wisconsin, resulted in most rivers reaching or exceeding flood stage. Thunderstorms and cloud-to-ground lightning were reported across the southeastern counties.
