SQUAM LAKE, N.H. (AP) — A heat wave from the Midwest to New England moved closer to a breaking point Thursday as millions of people sweated out another day.
The National Weather Service predicted it would peak in the eastern Great Lakes and New England Thursday and in the Ohio Valley and Mid-Atlantic by the weekend.
Heat index readings combining temperature and humidity were expected to surpass 100 degrees (37.7 C) in many locations, possibly setting some all-time records, the weather service said, and because record overnight temperatures could prevent natural cooling, heat danger could build up indoors.
In a study published Thursday, a group of scientists said human-caused climate change has drastically increased the odds of experiencing the killer heat baking the Southwestern United States, Mexico and Central America this month. Last year, the U.S. saw the greatest number of heat waves — abnormally hot weather lasting more than two days — since 1936.
Ocean waters are warmer as well, particularly in the Gulf of Mexico, where the season’s first named storm, Alberto, was dumping heavy rain and flash flooding along a stretch of the coast from Mexico to Louisiana. Hurricane season this year is forecast to be among the most active in recent memory.
It’s made for an unusually early start to summer extremes in the northeastern U.S. In New Hampshire, Angela Wilcox took her two children and two nephews boating Thursday in search of the coldest swimming spot on Squam Lake, where they’ve stayed at the rustic Rockywold Deephaven Camps near the town of Holderness for 16 years.
“This is the hottest it’s ever been, especially in June,” Wilcox said. “We’re kind of shocked.”
Camp workers were delivering large blocks of ice to the cabins for refrigeration. A tradition at the camp for more than a century, the ice is harvested from the lake each winter and packed with sawdust in an insulated storage hut. The method has kept fresh ice available throughout the summer and into the fall.
It was already nearing 90 degrees (32.2 C) as John Dupont opened his kettle corn stand at Concord’s 50th annual Market Days Festival. He and his daughter set up two fans and were prepared to drape icy towels around their necks.
“This year is a little challenging because of all the heat. Our kettle gets up to 150,000 BTUs,” he said.
At Johnson’s Dairy Bar in Northwood on Thursday, Camryn Hildredth tried offer customers an empty dish for that heartbreaking moment when a scoop of rapidly melting ice cream topples out of the cone, but not all would listen.
“Everybody asks if we have AC. We do not,” she said. “It’s very hot and we get long lines, so it can get very rough sometimes.”
In Burlington, Vermont, Jack Hurlbut said he’s never been so hot in his life. “I live in Vermont for a reason, you know what I mean?” the 28-year-old said.
Hurlbut, who is experiencing homelessness, joined others in a shady spot on a lawn outside the public library, which was serving as a cooling center.
Officials have urged people to stay indoors if they can and check on vulnerable family members and neighbors.
New York parks had free admission Thursday, and select state-run pools and beaches opened early for swimming, Gov. Kathy Hochul said. New York City’s beaches were available and while its public swimming pools don’t open until next week, the city keeps a list of hundreds of free air-conditioned sites.
“The humidity is pretty insane,” said Anne-Laure Bonhomme, a health coach who was sightseeing in New York with her family.
Many school districts in New Jersey switched to early dismissals as the school year winds down, and at least two rescheduled their high school graduation ceremonies due to concerns about excessive heat and humidity.
With much of Indiana broiling in the 90s, highway crews are starting shifts at 6 a.m., two hours earlier than in cooler seasons, and taking more frequent breaks in air-conditioned trucks in between filling potholes and other roadwork, said Kyleigh Cramer, a spokesperson for the Indiana Department of Transportation.
“They’re able to get in those trucks and cool off right then and there because being out on the road is a little bit different than being in an office,” Cramer said.
Some relief is coming: A cold front is moving into areas near Lake Michigan on Thursday and Friday, the weather service said. Chicago broke a 1957 record Monday with a high of 97 degrees (36.1 C).
