Severe thunderstorms developed over the region during the late afternoon hours of July 5th. There were numerous reports of large hail and damaging winds. The most intense winds occurred along a path stretching from just south of Saginaw to just north of Pontiac. These intense thunderstorm winds, gusting as high as 70 MPH, brought down many large trees. Remarkably, only a few homes sustained minor damages. There were also reports of large hail, some the size of ping pong balls. Numerous trees were also blown down across Livingston County, especially around the Fowlerville area. By sunset, the atmosphere became less capable of supporting severe thunderstorms and the event was over. No injuries were reported. At least 50 thousand customers lost power.
