Time to bring in the plants. The area could see its first frost Monday morning as temperatures dip into the 30s for the first time since April in Baltimore and surrounding counties.
The National Weather Service has issued a frost advisory for multiple counties around the state — including Anne Arundel, Carroll, Baltimore and parts of Howard and Harford counties, as well as in Baltimore City.
A frost advisory means that widespread frost is expected, and could kill sensitive outdoor plants that are left uncovered.
A first freeze in places like Westminster and Frederick would be right on time, according to the University of Maryland Extension. It usually comes by late October there.
At BWI, the first freeze arrives by Oct. 28, on average. In Baltimore City, it often doesn’t come until mid-November.
