No, it’s not just you. The National Weather Service has issued an excessive heat warning from noon to 8 p.m. for the New York metropolitan area. Sunday is forecast to hit 95 degrees, but the “dangerous” combination of the temperature and humidity will make it feel more like 105 degrees outside. For those in the city: Drink water and hug your air conditioner tight. For those still out of town for the holiday weekend: Figure out a way to stay wherever you are, possibly until summer ends.
