The wider storm

An unstable atmosphere was in place ahead of a strong cold front moving into the region from the west and a weak warm front located across northwestern Indiana. These features combined with a high shear environment supported development of thunderstorms across northern Illinois. These storms moved across southern Lake Michigan, producing gusty winds as they came onshore.

Began near St Joseph Glos Station (sjom4) (42.1000, -86.4900).
