Decatur, IL – Gardeners across central Illinois should prepare for a sudden temperature dip overnight, as a frost advisory threatens sensitive plants across more than 20 counties from 2 a.m. to 8 a.m. Wednesday.
According to the National Weather Service in Lincoln, temperatures are expected to fall to near 33°F early Wednesday morning. The advisory spans portions of central, east central, southeast, and west central Illinois, including cities such as Decatur, Peoria, Champaign, Urbana, Mattoon, and Galesburg.
Frost formation is likely, which could damage or kill unprotected outdoor plants. Officials urge residents to cover tender vegetation or bring potted plants indoors before temperatures drop.
