Severe Thunderstorm Watch numbers 386 and 388 were in effect during this event.
Scattered severe thunderstorms developed late in the afternoon ahead of a shortwave mid-level trough and along and ahead of an associated surface cold front. Thunderstorms continued through most of the evening before weakening shortly before midnight. These storms produced large hail through the early evening hours while they were discrete and supercelluar. Later in the evening the storms congealed into a quasi-linear convective system and produced severe thunderstorm wind gusts.
