The looming frost could potentially kill “sensitive” outdoor vegetation, the NWS said. Residents are advised to bring their plants indoors.
For Chicago and the south suburbs, the rest of the weekend will dip to lows in the upper 30s to 40s, the NWS said. Temperatures are expected to heat up again next week in Chicago, however, with highs in the 70s slated for Monday to Wednesday.
