Two rounds of severe storms raced across portions of central and northern Wisconsin on April 9th and April 10th.  The first round of storms affected northern Wisconsin between about 5 pm CDT and 8 pm CDT producing hail up to 1 inch in diameter. The second and more intense round of storms raced across central and north-central Wisconsin between about 1130 pm CDT April 9th and 3 am CDT April 10th producing hail up to 1.75 inches in diameter, straight line wind damage and at least one tornado. 

The hardest hit area was just west of Wausau where a brief tornado touched down about 6 miles WNW of town.  The tornado caused significant damage to two structures and minor damage to several others along its 1/2 mile path.  A preliminary NWS damage survey estimated maximum winds of 105 mph (EF1).

Microbursts (straight-line thunderstorm winds) produced significant wind damage near Minocqua in Oneida County and near Marshfield in northern Wood County. Winds were estimated over 75 mph in these storms.
