Tens of millions of Americans across the Northeast and Mid-Atlantic are baking under sweltering temperatures, with New York City recording its hottest day in 14 years as the country braces for massive semiquincentennial celebrations. 

Temperatures have skyrocketed into the late 90s and even hit 100 degrees Fahrenheit in the Big Apple on Thursday, as meteorologists anticipate the intense heat to persist until Sunday. 

The city’s official thermometer, stationed in Central Park, recorded a temperature of 100 degrees at 1.51pm, hitting three digits for the first time since July 18, 2012. 

Newark Liberty Airport reached a high of 104 degrees, breaking the previous record of 102 in 1966, according to preliminary data from the National Weather Service. 

LaGuardia also recorded a record-high temperature of 104 degrees, surpassing the previous record of 101, set in 1966. Whereas John F Kennedy International Airport saw a high of 102 degrees. 

The last time the temperature reached 100 degrees on July 2 was in 1966. The blistering heat wave could not come at a worse time for New Yorkers, who have been inundated with press and travelers for a series of high-profile events. 

A-list celebrities are in town for Taylor Swift and Travis Kelce’s rumored nuptials on Friday night, celebrations across the city are anticipated for the July Fourth weekend and Norway will face off against Brazil at MetLife Stadium across the Hudson River on Sunday. 

New Yorkers have resorted to jumping into water fountains, taking their shirts off and busting open fire hydrants to find some relief.

The US Department of Energy issued two orders this week authorizing backup generation in the event of a serious grid emergency, while the city government has opened cooling centers for the most vulnerable communities. 

New Yorkers are not the only ones suffering from the heat, as temperatures approached 100 degrees in Washington, DC, Philadelphia and Boston. 

Cities across the Northeast broke records as temperatures hit over 100 degrees. Washington National Airport hit 102 degrees, breaking a 1898 record of 101. 

Philadelphia tied a record from 1901 of 103, while Boston hit triple digits for only the 29th time. 

The sweltering heat has posed a problem for the President’s grand July Fourth celebrations in honor of the country’s 250th anniversary. 

Organizers of the Capitol Fourth concert in DC banned the public from attending Thursday’s rehearsal because of the heat.

The concert is still scheduled for Friday, but attendees will not be let in until an hour before the show.

Attendees at Donald Trump’s Great American State Fair have also been forced to endure record-high temperatures. 

The president’s fireworks display on Saturday will come on a day with temperatures in the high 90s and potential thunderstorms. 

Despite the brutal forecast, the president has stood firm that the festivities will continue, even promising a ‘really long speech’ at the event’s conclusion. 

‘On July 4, it’s going to be approximately 107 degrees out, and I’m going to go, and I’m going to make a really long speech just to show that I can do anything,’ Trump said.

The President has promoted a series of events to celebrate America’s semiquincentennial, organized by Freedom 250, a Trump-backed nonprofit. 

Boston is also seeing record temperatures, hitting triple digits for only the 29th time. Bostonians tried to beat the heat by taking a dip at Good Harbor Beach on Thursday

Children could be seen crying about the limited shade and the few designated areas for relaxing, while bottles of water cost $5. 

However, a White House official told The Hill that complimentary water distribution stations will be set up on Saturday to beat the heat.
