CHICAGO (CBS) — The low for Wednesday night is 47 under partly cloudy skies.
Rain arrives with our next cold front by Thursday afternoon.
This front will bring a reinforcing shot of cool air into our area. The high for Thursday is just 58.
There will be enough instability over the lake Thursday evening and night for waterspouts to form. They will be nearly impossible to see, since it will be dark.
Showers may accompany the front along with isolated thunderstorms.
Once the front is through, we will have highs in the 50s right through the entire weekend. The high for Friday is only 54.
Widespread frost is possible Saturday morning if skies clear.
