Thunderstorms began over the west late this afternoon and have been spreading east and southeastward tonight. A funnel cloud was spotted by a trained National Weather Service spotter near Bark River this evening. In addition, the complex of storms that prompted a Tornado Warning for parts of south-central Upper Michigan earlier was responsible for flash flooding. At Foster City in Dickinson County, Cunard Road was washed out due to torrential rains. Farther west, a spotter near Ironwood reported a half-inch of rain in just 15 minutes.
A Severe Thunderstorm Watch is in effect for the west half of Upper Michigan until 1 a.m. central, 2 a.m. eastern time. The thunderstorms are developing ahead of low pressure that is expected to bring more rain on Friday into the weekend. In addition, temperatures will be much below average for late July both Saturday and Sunday.
