Hill City, Kansas/Chicago/New York — On Wednesday, soaring temperatures stretched from the Midwest to the east coast, placing tens of millions under heat alerts. This extreme weather is expected to persist through the Fourth of July celebrations, coinciding with America’s 250th anniversary.
The sweltering heat is set to elevate “feel-like” temperatures to between 100 and 115 degrees Fahrenheit (about 38 to 46 degrees Celsius) across vast areas, heightening concerns for vulnerable individuals and presenting challenges for power grids already pushed by increased demand from data centers and electric vehicles.
In Hill City, Kansas, a small town located 440 miles east of Denver, postal worker Sabrina Hooper faced temperatures surpassing 100 degrees on her first week of work. Hooper, 34, shared how the heat has affected her daily tasks, which involve walking up to 10 miles to deliver mail. She found some relief with sprinklers, saying, “It feels so good. I can take my hat off, get it wet, and slap it on my head again.”
Interestingly, Hill City experienced the highest temperatures in the U.S. for five days straight back in 2012, when a serious heat wave sent the town’s heat index to 108 degrees.
The heat index is essentially how temperatures feel when humidity is taken into account.
Meanwhile, Dana Robles in Brownsville, Texas, near the U.S.-Mexico border, expressed concern about rising cooling costs as the heat index hit 108 degrees. For her family, peak electricity costs can exceed $300 a month, nearly one-third of their rent. Robles worries about potential power outages as the grid strains under this heat.
“I’m worried that the electricity will be out all day and the food will spoil,” she remarked.
In Chicago, Michelle Klein, a 57-year-old high school science teacher, took precautions over the weekend for the impending heat. She filled up her car with gas, completed her grocery shopping early, stocked up on cold beverages, and ensured her plants received sufficient water.
Klein noted, “Basil has become a diva and needed an extra glass of water this morning,” while she completed her usual evening walk, despite the heat index reaching 103 degrees.
On the city’s fringe, real estate investor Amy Kasper received an emergency call from a tenant experiencing issues with their air conditioner. After checking, she discovered the system was functioning; however, the extreme temperatures and humidity made it inadequate for cooling.
Kasper, 50, humorously compared the heat, saying, “Coupled with the wind, it feels like I’m standing behind a bus exhaust in Chicago right now.”
Cooling Center and Check-In
The City of Chicago’s Office of Emergency Management and Communications advised residents on Wednesday to regularly check in on vulnerable individuals, like the elderly. If someone cannot be reached, residents can call 311 for a welfare check.
The extreme temperatures in the Midwest reflect similar conditions in Western Europe, where record heat waves have recently occurred. Scientists assert that such weather patterns would have likely been “virtually impossible” without the influence of human-induced climate change.
Research over the years has shown that greenhouse gas emissions are making heat waves both more frequent and severe globally.
As of Wednesday morning, extreme heat began to hit New York City, prompting the opening of numerous cooling centers and the deployment of “cool vans” stocked with water, electrolytes, sunscreen, and meals for those in need, as stated by Mayor Zoran Mamdani during a news conference.
At the Harlem senior center, air conditioning was working overtime, with signs in 13 languages marking the space as a “cooling center” for all. Senior Center Director Richard Allman mentioned the center would remain open beyond regular hours over the July 4 weekend.
“We try to make it a comfortable place for people even on very hot days,” he stated.
Before the heat wave, city officials requested that Times Square sign operators reduce their brightness to help conserve energy and advised businesses to set thermostats above 78 degrees.
Con Edison, the city’s energy provider, urged customers to limit their energy use during peak hours from 2 p.m. to 10 p.m.
Additionally, the city has extended public pool hours, opened more cooling centers in libraries and municipal buildings, and ramped up its outreach efforts on the streets.
