It will definitely feel like fall in southwestern Ontario on Friday night and Saturday morning.
Environment Canada has issued a frost advisory for Windsor-Essex and Chatham-Kent, with patchy frost possible overnight.
Low temperatures may flirt with the freezing mark, especially in rural or low-lying areas.
"Some plants that remain outside may be damaged by frost," read the advisory from Environment Canada. "Cover up plants, especially those in frost-prone areas. Take preventative measures to protect frost-sensitive plants and trees."
Similar conditions are also in the forecast for Saturday night.
