Scattered showers could develop as early as Friday afternoon, and an isolated thunderstorm is possible in the evening, NBC Chicago meteorologist Andy Avalos said.

Sunday remains mild and rainy. Highs could vary from the upper 60s north of Chicago to mid-70s south. It stays mostly cloudy, though, with showers and a few thunderstorms possible in the morning and storms more likely in the afternoon and evening.
