INDIANA — Any severe weather on Wednesday is expected to stay confined to areas right along the Wabash River on the Indiana and Illinois border. There is a very low chance for isolated hail and damaging winds, with a brief tornado possible only under the right conditions. The best chances for strong storms are focused on southwestern Indiana, including Terre Haute, Vincennes, and Evansville.
Best Storm Chances From Terre Haute to Evansville
The highest risk area stretches in a narrow corridor from Terre Haute south through Robinson, Vincennes, and Evansville. This zone hugs the Wabash River and extends east toward Bloomington, Bedford, and Jasper in southern Indiana.
Storms in this corridor will have the best chance to produce gusty winds or small hail as they move east during the afternoon. Even here, the overall severe threat remains low, and many locations may only see rain and a few rumbles of thunder.
Brief Tornado Possible but Highly Conditional
A brief tornado cannot be ruled out, but it would depend on storms tapping into enough instability and wind shear. Any tornado that does form would likely be short-lived and weak.
Storms along a line can spin up quickly with little warning, so residents in southwestern Indiana should keep a way to receive weather alerts close by. Knowing where to take shelter at home or work is a good step even on low-risk days.
Eastern Illinois and Western Kentucky See Rain and Lower Risk
Areas farther west in Illinois, including Charleston, Effingham, Flora, and Mount Vernon, are expected to see rain with a lower chance of strong storms. Champaign, Tuscola, Springfield, and Carbondale are also outside the main area of concern…
