Heat advisory issued for Centre County this week with high temperatures, humidity in the forecast

Happy Valley will be under a heat advisory for most of the week with high temperatures and humidity in the forecast.

The National Weather Service issued a heat advisory for central Pennsylvania, including Centre County, beginning noon Tuesday through 8 p.m. Thursday. The advisory states heat index values up to 100 are expected and hot temperatures and high humidity may cause heat-related illnesses.

The NWS expects the heat wave to continue into the weekend and to see the hottest temperatures of the summer so far.

“The longevity of the heat wave has not been experienced in decades during the month of June,” the advisory states.

The NWS forecast for State College shows high temperatures in the low- to mid- 90s this week. Even the low and overnight temperatures won’t provide much relief, Jonathan Guseman, meteorologist at National Weather Service State College, said.

“The overnight low temperatures aren’t going to recover as well. It’s not going to cool as much, so we’re going to have a prolonged period of exposure to warmer conditions,” Guseman said. The forecast shows low temperatures in the 60s and 70s throughout the week.

Guseman encouraged people to begin taking precautions now by hydrating and finding cool places to be. He also urged people to be extra cautious not to leave children in the car.

On the social media platform X, formerly Twitter, the Pennsylvania Department of Health shared heat safety tips, which include drinking water and avoiding alcohol and caffeine, wearing sunglasses, resting in the shade or indoors, wearing light and loose clothing and knowing the signs of heat illness.

When will there be relief from the heat? Guseman said it’s still too far out to know for sure but there are signs that it could happen late this weekend or early next week.

“This is still essentially early summer here. So hopefully we don’t see too many long periods of heat above normal but it’s not out of the ... question that we could,” Guseman said.
