| Brief Description: EVENT NARRATIVE: Several sheds and outbuildings were destroyed, as were a couple of barns. Hundreds of trees were snapped. The tornado was accompanied by strong rear flank downdraft winds that also knocked down numerous trees. EPISODE NARRATIVE: The morning of Wednesday July 14th had a complex of severe thunderstorms moving across eastern North Dakota, into portions of west-central and central Minnesota. This complex moved eastward during the morning, and intensified across portions of east-central Minnesota and west-central Wisconsin. Several waves of severe thunderstorms developed across west-central Wisconsin and began to reform westward into Minnesota by the early afternoon. These severe storms that reformed in east-central Minnesota, quickly moved into west-central Wisconsin by the mid afternoon and caused tornadoes and damaging straight-line winds. In addition to the winds and hail, several inches of rainfall caused flooding in Polk, Barron, St Croix and Rusk Counties. | |||||||||||
