According to the NWS, heat index values could reach between 100 and 102 degrees.
The heat and humidity may cause heat stress during outdoor exertion or extended exposure, and excessive heat can be life-threatening among at-risk people, which includes children, the elderly, and those with pre-existing health conditions, according to the NWS.

Upcoming weather: Weather forecasts project York County's current heat wave to continue into the weekend.
Craig Evanego, a meteorologist for the National Weather Service in State College, said the definition of heat wave varies based on location, but it is generally considered three or more consecutive days with temperature highs above 90 degrees.
The high temperature projected for Thursday, Friday, Saturday and Sunday are all above 90 degrees, according to the weather service, with the high for Monday expected to be 88 degrees.
Thunderstorms are likely Saturday and Sunday, leading to warm and muggy conditions, Evanego said.
Evanego suggested residents try to stay indoors with air conditioning, particularly during the late afternoon when temperatures are highest.
