A tornado destroyed much of a rural Bloomington farm. More than four inches of rain fell in some parts of Grant County, with additional reports of winds to 70 mph and hail up to 2 inches in diameter.
Tornado sirens briefly sounded in Platteville for what appeared to be a funnel cloud.
The first severe thunderstorm warning was issued around 6:35 p.m. for a severe thunderstorm near Prairie du Chien, moving southeast. A second severe thunderstorm warning was issued just before 7 p.m. for a severe thunderstorm near Patch Grove, also moving southeast.
The third severe thunderstorm warning was issued a half-hour later for a line of storms from Marquette, Iowa, to Muscoda, moving south. That warning was extended around 8:45 p.m. as the line of storms extended from Platteville to Balltown, Iowa.
The tornado warning for west central Grant County was issued around 7:35 p.m. The National Weather Service confirmed the tornado as an EF2 tornado late last week.
The tornado touched down at the Conrad and Wendy Myers farm on Maine Road and was witnessed hanging above their farm for 2½ minutes. The tornado ripped the roof off the house and destroyed a barn and shed.
Platteville firefighters were dispatched for storm spotting at 7:45 p.m. One-half hour later, the fire department activated the tornado siren at the request of a Platteville police officer.
No damage was reported.
