Do you like temperatures in the 60s? You might be pleased Saturday and Sunday mornings

The thermometer has hit 90 degrees or higher in Rock Hill on seven of the last eight days … 17 of the last 19 … and 23 of the last 25.

But forecasters say a break is on the way, at least for a few days.

A cool air mass is predicted to sweep into much of the Carolinas, including the Rock Hill region, for this weekend. And the cooler air will be accompanied by much lower humidity levels too.

National Weather Service meteorologist Clay Chaney called it “a brief taste of fall this weekend, temperature-wise.”

Daytime highs are predicted to reach the low 90s through Wednesday, with high humidity driving the heat index above 100 degrees both days.

Forecasters say the first of two cold fronts will approach the area later Wednesday, bringing a chance of showers and thunderstorms.

On Thursday, highs are forecast to reach only the upper 80s. A secondary cold front is expected to sweep across the area during the afternoon, bringing another chance of showers and thunderstorms.

But Rock Hill-region residents will awaken to much different conditions Friday, forecasters say.

Despite the August sunshine, afternoon high temperatures are predicted to reach only the upper 80s. And dew point temperatures, a measure of humidity, will fall from near 70 earlier this week to the upper 50s and lower 60s.

The lower humidity levels also will allow morning temperatures to fall to the low and mid 60s both Saturday and Sunday mornings. Afternoon highs over the weekend are predicted to be in the mid and upper 80s, with mostly sunny skies.

As Chaney said, it will feel a bit like early autumn.

But the calendar still says “August,” and more typical conditions will return early next week.

“The overall air mass will begin to modify, as we return to a more normal summertime pattern,” Chaney said.

That means highs likely will return to the 90s, with humidity levels also climbing.
