Detroit, MI– Chilly air is sweeping across Southeast Michigan tonight, triggering a frost advisory that could damage unprotected plants in multiple counties through early Thursday.
According to the National Weather Service in Detroit, temperatures are expected to dip as low as 32°F between midnight and 9 a.m. Thursday. The advisory includes areas like Flint, Ann Arbor, Pontiac, Port Huron, and Adrian—though Wayne County, including Detroit, is not currently under the alert.
Gardeners and growers are urged to take immediate action. Sensitive vegetation should be covered or brought indoors to prevent cold damage. Drivers in rural areas may also encounter patchy frost, especially near fields or low-lying terrain.
City and county emergency management teams recommend checking local advisories before traveling overnight or early Thursday. While no road closures are expected, drivers should plan for reduced visibility in frost-prone spots just before sunrise.
The advisory could be extended or expanded if temperatures drop further overnight.
