Two homes in Purdy were damaged on Wednesday by straight line winds.
According to David Compton, emergency management director for Barry County, the storm that moved through the Monett area on Wednesday night generated a microburst of intense wind that tore through the center part of Purdy around 11:20 p.m.
A home at Third and Washington received minor roof damage and a trailer around Ninth Street and Washington was blown off its block foundation. According to Compton, it could not be determined how well the trailer had been anchored to its foundation.
Compton said the National Weather Service confirmed on subsequent investigation that the damage was caused by straight line winds and not a tornado.
"Winds generated by a microburst can easily exceed 60 to 80 miles per hour," Compton said. "They can do significant damage. There's no way to forecast them."
The storm that blew through southwest Missouri on May 8 was similar to Wednesday's storm, only multiplied. Compton identified last week's storm as a derecho, a storm made up of clusters of microbursts that travel together for at least 250 miles.
Friday's storm produced 18 tornados in southwest Missouri. One was the size of an F2, in the Willard area. Most were F1 or F0 status, Compton said.
"A derecho looks like a land-based hurricane on the radar. One can easily drop tornadoes on its leading edge," Compton said.
