I don't know how much of an impact that this had, but I am going to throw it out there.
The local news in CLT reported that there were 17 days in July were a Thunderstorm was reported at the CLT airport, a normal July sees only 9 days with thunderstorms. This is only at the airport, not in the vicinity, nor enroute on any approaches, which I am sure would increase the total more. The report was this is the second highest July total on record. No business can profitably keep staffing around in case something so rare happens. It kills your productivity overall, for that extra staffing would normally not be used, but would still be receiving pay and benefits.
