I'm right on the Iredell/Rowan border right off HWY 801,youre a good 3 or 4 miles from me.That can make a huge difference when it comes to pop up t-storms.
I never expect cooler weather anyways till the first 5 or 10 days of October,
September for the most part is still warm and humid here but on occasion you do get lucky and it cools sooner.
