Every forecast across Metro Detroit, highway-clear.
Official National Weather Service forecasts for Metro Detroit — seven counties from downtown and the Grosse Pointes out past I-275 to Ann Arbor, Pontiac and Howell, north to Port Huron and south to the Monroe lakeshore.
Every Michigan region shares one system — the same maps, the same live radar, the same climate record.
