SUMMARY: Despite 12 days with thunderstorms and two tropical systems that affected the area, July was very dry with less than 50% normal rainfall. Many nearby surrounding areas were hammered on multiple occasions with heavy rain and strong storms. It was also a very warm and humid month with above normal temperatures. There was a lack of extremes but it was consistently warm with unusually mild overnight lows. High dewpoints contributed to the high number of days (14) with fog.
