As Americans gather to celebrate Independence Day, New York City is bracing for a sweltering heat wave that's expected to grip the city over the long holiday weekend. The National Weather Service has issued a heat advisory, warning residents of temperatures soaring into the mid-90s with humidity making it feel even more oppressive. With outdoor festivities and fireworks displays planned across the city, officials are urging caution and reminding people to stay hydrated and take breaks in cool, shaded areas. As the city's residents and visitors look to beat the heat, they'll also be keeping a close eye on the skies, where scattered thunderstorms are forecast to pop up throughout the day.
