Sep 3, 2011 Storm Damage Pictures in Iowa County

During the pre-dawn hours of September 3rd, a squall line, roughly orientated on a north-south line, moved east across parts of south-central and southeast Wisconsin. 

The squall line moved into the counties of Iowa and Lafayette around 230 am CDT, and finally exited over the Lake Michigan waters between 530 and 600 am CDT.

Estimated wind gusts of 60 to 80 mph resulted in uprooted large trees, snapped power-lines, and structural damage to farm buildings and at least one home.  Additionally, an above-ground, backyard pool was blown over.

Locally, brief, heavy rains resulted in some ponding of water on low-lying roads, and there were reports of water over the curb. 

The affected counties include: Iowa, Dane, Jefferson, Dodge, Waukesha, Milwaukee, and Ozaukee.  The counties of Lafayette, Green, Rock, Walworth, Racine, and Kenosha experienced the sub-severe effects of the squall line.  Damage was not reported from these counties.

In Iowa County, a cattle building about 4 miles south-southwest of Dodgeville was damaged.  In the area southeast of Dodgeville to northeast of Hollendale, another cattle building was destroyed, a barn was damaged, and some corn fields were flattened.   Below are pictures of some of the damage in Iowa County.

So - as the amount of sunlight during the day diminishes in this fall season....leading up to yet another winter season....the question asked is....will we have more thunderstorm-related severe weather in south-central and/or southeast Wisconsin?

The answer - possibly.

Looking back in weather history....on Oct 26th and Nov 22nd of 2010....3 tornadoes affected the counties of Racine and Kenosha.  On January 7, 2008, 2 tornadoes affected Kenosha County.  On October 18, 2007, we issued severe thunderstorm warnings for 4 severe weather events.  On November 5, 2005, we issued a severe thunderstorm warning for 3 severe weather events.  You get the picture.
