'Air that you can wear': High temperatures expected in region into next week, humidity returning

JOHNSTOWN, Pa. – The heat is coming.

The end of June is bringing temperatures that are expected to soar into the high 80s and low 90s Monday through July 4.

"We're going to have this pretty big ridge of high pressure move into the east and central United States, and it's going to get hot. There's going to be highs well into the 90s in most locations," said Peyton Simmers, a meteorologist with AccuWeather.

"Heat domes do happen in June, even though we expect them more in July and August at the peak of hot summer weather, but it's not unusual."

He said that along with the higher temperatures, humidity also will be on the rise.

"We're going to have the return of dew points into the mugginess, and it's going to feel like true summer," Simmers said. "Tuesday, Wednesday, Thursday and Friday is when it's going to be hot and humid. This will be air that you can wear."

He said while the temperatures will be high, precipitation chances will be low in Cambria and Somerset counties next week.

"High pressures squash precip chances, so at best we might get some storms to maybe fire up on the mountains," Simmers said. "That will provide minimal relief for the lucky few who would maybe get some."

He said the heat will begin to subside by July 4.

"It's still going to be warm, it wouldn't be cold by any means, but it'll pull back into the 80s," Simmers said. "It'll still be muggy, but not as oppressive. That also could be accompanied by a couple thunderstorms, and that's a typical summertime pattern. Whether that rains out any firework displays remains to be seen."

He said with the higher temperatures, people should take precautions to alleviate potential health issues associated with high heat.

"What people should wear is loose-fitting clothing and bright clothing like white and yellow that doesn't soak in the sunlight," Simmers said.

"Make sure you drink plenty of fluids like water and Gatorade to replenish electrolytes. If you're working outside, take as many breaks as you can, or stay indoors as much as you can. You also need to avoid alcoholic beverages, which tend to dehydrate you."

He also said people should know the signs of heart stroke and heat exhaustion.

"If someone starts to experience that get them inside and get them medical attention right away," Simmers said.

Pet owners also need to be aware of the dangers heat can have on animals.

"Have somewhere shaded where they can go and have fresh water for them," Simmers said. "Don't leave pets outside for hours on end, and get them inside into some air conditioning when it's hot."
