Thunderstorms developed in a highly unstable environment ahead of an approaching cold front.  Several discrete cells initially formed across the area, producing numerous reports of large hail.  Eventually the cells merged into a bow structure, creating an enhanced damaging wind threat.  A few discrete cells maintained themselves ahead of the bow, with one of the cells producing a tornado in Edgar County.
