Wider weather episode

An area of low pressure working across the Upper Midwest on the 10th was able to pull abnormally high moisture into the region leading to sufficient instability for the development of storms. An upper jet was also over the area contributing to higher than normal amounts of shear as well resulting in some of the storms becoming severe across the region. Isolated reports of large hail and damaging winds were received along the North Shore of Lake Superior along with a rare October tornado that developed over the Boundary Waters Canoe Area Wilderness and tracked northward into Canada.
