Today: Fog will begin to lift through the morning leaving behind mostly cloudy skies. Afternoon highs will be in the low 70s. A few showers are possible, but mostly near and east of the I-55 corridor.  

Tonight: Mostly cloudy skies will continue with lows in the lower 60s. 

Tuesday and Wednesday: Showers and storms ahead of an approaching cold front will begin in the afternoon to evening hours. This will continue into the overnight hours before the main line of storms moves through during Wednesday. 

Storms could be on the strong to severe side capable of producing all modes of severe weather. The front will begin to slow over the area allowing for continual rainfall that introduces the risk for heavy rains and flash flooding. Rainfall totals may be between 2 and 4 inches with locally higher amounts possible. Make sure you have multiple ways to receive alerts over the next few days. 

Beyond: Behind the front, cold air advection will take hold and winter-like temperatures will return as high temperatures struggle to reach into the 60s. Sunshine will also return, and overnight lows will fall into the 30s and 40s.
