The Nationwide Storm Prediction Middle has the Chicago space in a Marginal to Slight Danger of Extreme thunderstorm potential Wednesday afternoon/night (see yellow/darkish-inexperienced shaded areas respectively on the highlighted extreme climate outlook map). The middle of strongest storm exercise seems to be in Arkansas into southeastern Missouri (Enhanced Danger tan-shaded space on the highlighted map).
A chilly entrance preceded and accompanied by a band of robust to extreme thunderstorms is forecast to cross the Mississippi River and strategy Chicago from the west Wednesday afternoon, passing by means of our space through the night/in a single day. Damaging winds, giant hail and downpours would be the main danger in a few of the strongest storms right here – though a twister or two can’t be dominated out. Extra widespread extreme storms will in all probability happen to our south throughout central and southern Illinois and farther south within the aforementioned Arkansas-Missouri space.
