Wider weather episode

A line of thunderstorms developed ahead of an approaching cold front during the afternoon across western Wisconsin and tracked through northeast Wisconsin through the evening hours on Wednesday (6/15). The storms formed into a Quasi-Linear Convective System (QLCS) with multiple reports of damaging winds of 70 to 80 mph as well as 10 tornadoes embedded within the main line of thunderstorms. The 10 tornadoes ties a record for the most tornadoes in an event for northeast Wisconsin. Additional storms late in the evening produced a few reports of large hail near the lakeshore as they moved offshore.

The swath of damaging winds caused multiple power outages, with over 125,000 customers without power across northeast Wisconsin. Power was not restored for several days across many areas as the cleanup from the storms took an extended period of time.
