Springfield, IL — A new round of showers and thunderstorms is forecast to roll across central and western Illinois beginning Tuesday afternoon, bringing with it much-needed relief from recent heat — but also the potential for localized flooding, downed tree limbs, and slick roadways.
According to the National Weather Service (NWS) in Lincoln, the system’s movement will create a dramatic shift in weather from humid highs in the 80s to storm-cooled temps by midweek. While western and central counties brace for activity starting Tuesday afternoon, eastern Illinois communities, including Danville and Paris, are expected to stay dry until closer to midnight.
