Storms packing winds as high as 55 mph blew through southeastern Wisconsin Wednesday evening, May 17. Those winds are believed to be the cause of at least two large trees that fell on homes in Wauwatosa. 

One crashed into the roof of a house around 7:30 p.m. Wednesday.

The Wauwatosa Fire Department responded to the home in the 600 block of North 76th Street and found there were not any injuries from the incident.

The tree fell from a neighbor's house and hit the southeast corner of the home's roof.

"The homeowner was in the basement and heard a loud crash," Wauwatosa Fire Deputy Chief Brent Lee said. "They came upstairs and found the tree."

Lee said no one in the area heard thunder at the time of the incident and that led to the conclusion that it was the wind that had brought it down.

The extent of the damage is currently unknown. The resident of the house, Lona Crego said the tree hit a bedroom and that branches had stuck through the roof into the house.

Wauwatosa crews were also spotted Thursday, May 18 cleaning up a tree resting against a house in the 1100 block of North Glenview Avenue.

WTMJ4 meteorologist Jesse Ritka said she had received reports of winds as high as 55 mph in Waukesha and 54 mph in Milwaukee.

Ritka said there were two rounds of severe storm cells that came through southeast Wisconsin early in the evening Wednesday and a squall line that came through around 11 p.m.

"The biggest trees will come down with winds at 40 mph if they are old and have shallow root systems," Ritka said. "If the ground is soggy they are even more likely to come up."

Ritka said squall lines started off as isolated storms but as they push forward they form together. She said the one that came through our area around 11 p.m. touched off tornado warnings in Walworth County and formed into a "bow echo," a damaging formation for a storm.

The storm caused power outages throughout the area but a spokesman for We Energies said he had not heard of any in Wauwatosa.
