A couple rounds of rain will move through central Illinois. The first will be through the early to mid evening hours, which should be relatively light and scattered. A second round should move in from Iowa after midnight, with on and off chances through the overnight hours.
Some linger showers and storms will be hanging around Saturday morning, especially to the north of I-74. We may catch a little bit of a break from the rain through the mid day to afternoon hours. We expect storms to fire back up by late afternoon across the area. There is a slight risk for severe weather for most of central Illinois. Primary threat will be damaging winds and larger hail. Storms that develop will likely have some heavy rain along with frequent lightning at times.
Cold front will move through the region during the morning hours. A line of storms should begin to develop near the I-55 corridor and continue to march east. Once this boundary moves out, we should be in the clear from rain through the rest of the day.
Another cold front will move through the area during the afternoon, sparking showers and storms across the area.
BIG COOL DOWN COMING:
The cold front moving through Monday will bring in a significant cool down for July standards to the area on Tuesday. Highs will struggle to hit 70 for many Tuesday afternoon (average high is in the mid 80's). Overnight lows will be cool, but not extremely cool, dipping down into the mid 50's. The unseasonably cool temperatures look to continue for most the work week.
