Summer is hot and getting hotter as temperatures will continue to rise the rest of this week with potentially record-breaking temperatures on Saturday.

The National Weather Service is predicting a high temperature of 100 that day. Add intense humidity, and it will feel more like 104 degrees, said David Martin, weather service meteorologist.

The record high for the York area for July 7 is 101 degrees, Martin said.

Temperatures have been running about 10 degrees above normal, and that trend will continue until Monday, when a high of 84 degrees is forecast.

The average temperatures for this time of year are a high of 85 and a low of 66, Martin said.

Between now and then, expect a high in the mid-90s on Friday, Saturday's triple digit forecast and a slight cooling to about 90 degrees on Sunday.

There's a 20 percent chance of thunderstorms Thursday night and a 30 percent chance on Saturday and Sunday nights, according to the weather service.

"If they have air conditioning, they want to stay home, they don't want to come out in the heat," Jones said. "They pretty much stay home, which with some of their health conditions is what they're supposed to be doing."
