Weak front to put dent in Carolinas’ September heat

A weak cold front is forecast to take a bite out of the midsummer heat that has toasted the Charlotte region this week.

National Weather Service meteorologists said the front will bring clouds, a higher chance of afternoon and evening thunderstorms, and slightly cooler temperatures Wednesday.

That could put an end to the streak of 90-degree days, which reached four with a 94-degree reading Tuesday in Charlotte. Forecasters said they expect highs in the upper 80s for the rest of the week, and then even cooler conditions are predicted for early next week.

Meteorologist Rodney Hinson said thunderstorms Wednesday could produce locally heavy rain in the mountains and foothills. And as the storms move into the Piedmont later in the afternoon and evening, they could be accompanied by strong winds.

“Some of the storms will be severe, with damaging downburst winds as the main threat,” Hinson said.

He said storm activity will decrease as the sun sets Wednesday, but some thunderstorms could continue overnight, he added.

The weak frontal system is forecast to stall in the area, then push back northward Friday as a warm front. Scattered showers and storms are expected Thursday and Friday, but they will be less numerous than on Wednesday, forecasters said.

A stronger cold front is predicted to arrive late Saturday, bringing a chance of strong thunderstorms and heavy rain to the Carolinas on Saturday and Sunday. That front is expected to push slowly south of the area Monday, and high temperatures in the cooler air behind the front are only forecast to reach 80 degrees in Charlotte early next week.
