What’s behind Charlotte’s temperature swings?

The Charlotte area is likely to experience another wild temperature swing this weekend.

Thursday’s high of 88 was a full 10 degrees above the normal high.

Now get ready for the mercury to gradually fall.

Expected highs Friday and Saturday will remain unseasonably high at a respective 84 and 80. The region has a slight, 30-percent chance of showers Friday, while Saturday and Sunday should be sunny.

Sunday, meanwhile, could see a high of only 72 and Monday 73, according to the National Weather Service in Greer, S.C.

What’s behind the temperature swings?

First, a cold front will move east across the area Friday morning through early afternoon. Drier air is expected to spill into the region Friday afternoon into Saturday, NWS forecasters said.

Second, a reinforcing cold front should arrive from the northwest Saturday night. That will bring an even cooler and drier high pressure system to the area Sunday into Monday.

A moist southerly flow is likely to return through midweek, with steadily increasing shower and thunderstorm chances.
