The National Weather Service issued a tornado watch Thursday night for six southeast Michigan counties, putting parts of the region under overnight alert until 2 a.m. Friday as severe weather moved through Metro Detroit on June 11.
Brandon Carr, who covered the overnight weather alert, said the watch stretched across Bay, Genesee, Livingston, Midland, Saginaw and Shiawassee counties and included cities such as Bay City, Brighton, Durand, Flint, Fowlerville, Howell, Midland, Owosso and Saginaw. For residents trying to track Grand Rapids weather and conditions farther east, the message was simple: stay alert and be ready to act if the forecast turned more dangerous.
The watch mattered because it covered a broad stretch of southeast Michigan during the night, when storms can move quickly and warnings can come with little time to spare. A tornado watch means conditions are favorable for the development of tornadoes and severe thunderstorms in and close to the watch area. It does not mean a tornado has been spotted.
That distinction matters. The watch signaled the ingredients were there, but it stopped short of saying a tornado had touched down or even been observed. Forecasters told residents in the watch area to monitor weather updates and be prepared to move to shelter if warnings were issued.
What remained unresolved by late Thursday was whether the weather would strengthen further before the watch expired at 2 a.m. Friday. For the people in those six counties, the overnight question was not whether the skies were unsettled, but whether the next alert would be a warning that demanded immediate shelter.
