ROCKFORD (WREX) – Strong storms and heavy rainfall struck central Illinois Monday evening and avoided our area, but the Stateline may not be done with rain chances yet.
A low and a warm front will move through central Illinois tonight. This storm system created a line of severe thunderstorms south of Champaign. Flash flooding, severe wind gusts, and possible tornadoes all occurred over a stretch of the middle of the state. Farther north, the Stateline saw a quick line of downpours in the afternoon, but otherwise only saw lighter rain showers.
The rain clears the area after midnight. Any strong storm activity will stay south of I-80. We’ll be in for a dry rest of the night, with lows in the 60’s. Tuesday starts out partly cloudy and dry, with highs in the low 80’s.
Tuesday afternoon could see more showers and storms. These will be more of the “pop-up” or “popcorn” variety, in that they may be widely scattered and not all areas will see rain. The storms will also develop quickly so stay alert. Those that do have a storm cross their path may see heavy downpours and strong winds. As a friendly reminder, do not drive into any flooded roads if you do encounter them. The pop-up storms will dry up by sunset.
Another chance at scattered showers is possible Wednesday afternoon. This is just a slight chance for now, and any rain would be lighter. We’ll dry out for the tail end of the work week, then showers and storms may be possible again Saturday. Slight chances may pop up Friday and Sunday as well.
Temperatures will cool off a lot and fall into the middle 70’s by midweek, then rise again to the middle to upper 80’s by the weekend. We’ll see the humidity fall and rise with the temperatures, going from comfortable to muggy between midweek and the weekend.
