Active August 2021

Overview

A very busy six day period occurred to start the month of August across much of Wisconsin. Multiple days of strong to severe storms resulted in hail, damaging winds that knocked down trees and powerlines, as well as a few tornadoes. The biggest severe weather day and most widespread damage occurred on August 10th, 2021. Near record instability present across southern Wisconsin resulted in a line of thunderstorms that moved from west to east and produced persistent wind gusts of 40 to 60 mph for upwards of 20 minutes. A stronger core of winds was noted from east of Janesville to southern Waukesha, to New Berlin, and then into West Allis. In particular a gust of 77 mph was recorded in Eagle in Waukesha County. Hundreds of thousands of customers across southern Wisconsin were without power and it took multiple days to restore power to all of the impacted customers. We-Energies stated this was likely the largest outage in the companies history and the largest restoration effort they have ever embarked on.

In addition to the strong to severe storms this stretch of active weather brought some much needed rainfall to ease the ongoing drought conditions. Much of southern Wisconsin entering the month of August was between 9 to 10 inches below normal for rainfall for the year. While some locations were able to receive upwards of 8 to 9 inches of rainfall this was not widespread. On average much of Wisconsin received between 2 to 3 inches of rainfall. While that did help portions of southern Wisconsin along the Wisconsin and Illinois border remain in severe drought.

Overview

Storms started by early afternoon across southeastern Wisconsin from Madison northeast into Sheboygan. Strong wind gusts of 63 mph were reported in Sheboygan with some tree damage. Storms continued to slowly move south to southeast with very few additional reports of damage. It wasn't until later into the evening did additional hail and damaging wind reports occur. A few spotters reported some brief funnel clouds west of Whitewater in Rock County but no damage or tornadoes were reported from these reports. Main thing that came with this round of storms was some beneficial rainfall.

NWS Milwaukee discussing the busy days ahead with multiple chances for severe weather through the weekend.

Overview

Multiple rounds of thunderstorms were observed on Saturday August 7th. The morning round was a decaying Mesoscale-Convective-System (MCS) that had developed over Minnesota earlier and was moving southeast into southern Wisconsin. A few stronger wind gust were observed with these storms. Then a warm front lifted north across southern Wisconsin into central Wisconsin. With much of the area now solidly in the warm sector additional storms began to develop over western and southwestern Wisconsin Saturday afternoon. A few supercells developed to the west and ended up producing an EF-1 tornado in Iowa County. The storms eventually morphed into a complex of storms that continued east and a few additional reports of damage were observed. By the overnight period storms began to back build along the Lake Michigan shoreline and heavy rainfall and minor to moderate flooding was observed in Milwaukee, Washington, and Ozaukee counties.

NWS Milwaukee multiple rounds of storms with main severe threat in southern and southeast Wisconsin.

Overview

A strong to severe line of thunderstorms developed across far southwestern Wisconsin Tuesday afternoon. As this line moved east it initially had a gust front get out ahead of the main line of storms which resulted in only brief severe gusts. But by the time got east of Madison additional thunderstorms were moving north out of Illinois and this resulted in widespread severe wind gusts occuring over much of southern and southeastern Wisconsin. We-Energies reported over 200,000 customers without power, which was the highest number ever for the company. The environment that day featured near record instability or CAPE based on the soundings from Davenport, IA and Green Bay, WI. This combined with hot surface temps in the 90s set the stage for the strong to severe wind potential to be realized.
