Another record is expected to fall as temperatures will likely reach 103 degrees today, according to the National Weather Service.
That will break the record set in 1956. It will also come close to the record-tying day in Rock Hill on Thursday as temperatures climbed to a sweltering 104 degrees.
That's the hottest it's been since Sept. 6, 1954, when temperatures also hit 104, the hottest day on record in York County, according to the NWS.
But try not to sweat it, a little relief is on the way.
A mild cold front will begin moving into the area by Saturday, bringing temperatures down into the mid-90s, said Harry Gerapetritis, a meteorologist with the National Weather Service.
Saturday should see a high of 95, Gerapetritis said.
"I guess after you've had 102 and 104, that's pretty cool after that," he said.
After Monday, temperatures will begin to creep back up, Gerapetritis said.
A spokeswoman at Piedmont Medical Center said the hospital treated several cases of heat exhaustion Thursday. The symptoms of heat exhaustion are nausea, vomiting and passing out. It can be treated with fluids.
There is another heat advisory today, which means the heat index is expected to be at or above 105 degrees. The heat index is what temperature it feels like when you consider both the heat and the humidity.
The heat advisory lasts from noon until 8 p.m., Gerapetritis said.
"It probably is best if people limit their outdoor activities," he said.
School-sponsored practices and activities after 11 a.m. in Rock Hill are canceled today, said Elaine Baker, district spokeswoman.
"It's a precaution," she said. "We don't want anything to happen to anybody. The heat's just out of the ordinary this week."
Although the heat is too much for many, there's at least one place in Rock Hill where a heat wave is not a bad thing.
"The warmer, the better," said Phil Holmes, co-owner of PW's ice cream shop on Herlong Avenue.
Holmes said business definitely has increased with the heat.
But even amid a room full of freezers, Holmes said he wouldn't mind if it was a bit cooler.
The increased heat also has led to increased power usage.
Duke Energy set a record for power output Wednesday as temperatures hit triple digits.
