There’s a new chance for severe thunderstorms in north central and northeastern Indiana this evening. The Storm Prediction Center issued Mesoscale Disucssion #912, which indicates a 40 percent probability that SPC will issue a severe thunderstorm watch in Kosciusko and surrounding counties, possibly including Whitley and Huntington Counties. According to the mesoscale discussion, a cluster of storms over northeastern Illinois has evolved into a small bow echo along the eastern fringe of an environment where vertical shear and instability support organized storm structures. While the atmosphere downstream is not quite as favorable, it might support a threat for isolated damaging wind and hail in the next few hours.
Stay alert for a possible watch and then for possible warnings, especially in and near Kosciusko and Marshall Counties.
