Areas along the western edge of Indiana have a slight risk of severe weather between 8 a.m. EDT tomorrow and 8 a.m. EDT Friday, according the “Day 2 Convective Outlook” that the National Weather Service Storm Prediction Center (SPC)  issued at 1:16 p.m. EDT. The slight risk area also includes most of Illinois and parts of several other nearby states to the west and south.

The greatest threat in the slight risk area is damaging straight-line thunderstorms winds of 58 mph or stronger, from a squall line that forecasters expect will develop tomorrow afternoon.

The SPC will update its outlook for tomorrow when it issues the first of several “Day 1 Convective Outlooks” at around 1  a.m.
