CHICAGO (WLS) --The National Weather Service has issued a Frost Advisory for the entire Chicago area from 1 a.m. to 8 a.m. Sunday.
ABC7 Meteorologist Larry Mowry said overnight lows are expected to dip to the low-to-mid 30s away from downtown Chicago and Lake Michigan. Patchy areas of frost are most likely in outlying areas away from the city.
"We probably won't see much frost in the heart of the city thanks to the heat island effect," Mowry said. "The farther north you go, that's where the coldest temperatures will be."
Plants that are sensitive to frost should be covered or brought indoors.
