The National Weather Service has issued a frost advisory from 2 a.m. to 8 a.m. today for the Indiana counties of Allen, DeKalb, Elkhart, Kosciusko, LaGrange, Marshall, Noble, St. Joseph, Steuben and Whitley. A frost advisory means that frost is possible during these hours.
Light winds and clear to mostly clear skies will allow temperatures to drop into the mid-30s overnight. Areas of frost are expected over far southern lower Michigan with patchy frost over the northern portions of northern Indiana and northwest Ohio. The advisory has been issued for areas mainly north of a line from Plymouth to Fort Wayne to Napoleon, Ohio.
Frost may damage unprotected sensitive plants and may kill them if left uncovered.
