A cold front passed through the area on July 1st. A southerly flow ahead of the boundary caused warm and humid air in place, which led to an unstable atmosphere. The instability combined with lift from the cold front caused thunderstorms to develop. Some thunderstorms produced gusty winds due to stronger sheer profiles from an upper-level trough overhead along with the unstable atmosphere.
