Gaylord, MI – A widespread frost advisory is in effect across parts of northern and southeast Michigan overnight May 11–12, with temperatures expected to fall to around 32 degrees.
According to the National Weather Service offices in Gaylord and Detroit/Pontiac, the advisory begins at midnight and continues through early Tuesday morning, ending at 6 a.m. in northwest Lower Michigan and as late as 8 a.m. in southeast portions of the state.
Affected areas include Leelanau, Benzie, and Manistee counties in northwest Michigan, along with a broader stretch of southeast Michigan including Saginaw, Flint, Detroit, Ann Arbor, Pontiac, and Monroe. The coldest conditions are expected in inland locations where winds remain light and skies stay clear overnight.
The primary concern is frost formation that could damage or kill sensitive outdoor vegetation. Early-season gardens, flowers, and crops are especially vulnerable during this late-season cold snap.
Residents are urged to take precautions Monday night by covering tender plants or bringing them indoors if possible. Even a few hours of near-freezing temperatures can have a significant impact on unprotected vegetation.
Temperatures are expected to rebound after sunrise Tuesday, bringing an end to the frost threat by mid-morning.
This cold stretch serves as a reminder that despite recent mild weather, frost risks remain across Michigan well into May.
