New York City has not dealt with an official heat wave since July 2013. That streak will end through early in the new week as heat and humidity make a comeback.
A building ridge of high pressure will keep the door open for heat and humidity to make an extended stay in the Northeast.
Temperatures will rise daily into the 90s through at least Tuesday, challenging record highs and causing the city to endure its first heat wave since July 2013.
A heat wave is defined as three consecutive days with highs of at least 90 F. The official weather observation site for New York City is Central Park.
"So far this year, New York City has hit 90 or higher on eight days, as of Aug. 15," stated AccuWeather Senior Meteorologist Alex Sosnowski. "This is already more than in 2014, which had eight days of 90 or higher. The average for Manhattan is 15 days."
The return of higher humidity will cause AccuWeather RealFeel® Temperatures to dangerously flirt with the century mark during the midday and afternoon hours (the hottest times of the day).
Residents and visitors are urged to drink plenty of water, wear light clothing and avoid strenuous activities during the day's hottest hours. If air conditioning is not available or fans are not providing enough cooling, seeking out a shelter or shopping center. Remember to never leave children or pets in a sealed vehicle.
"Heading to the beach will be a good idea [to beat the heat], as temperatures will stay in the 80s and the threat for thunderstorms, especially on Sunday and Monday, will be low," stated AccuWeather Meteorologist Brian Thompson.
"The water is also more comfortable now that we're in the second half of August," Thompson continued. "Water temperatures are now in the 70s from the southern New England coast through the mid-Atlantic."
Blazing sunshine will dominate Sunday and Monday before thunderstorms dot the area Tuesday afternoon.
The thunderstorms will not mean that noticeable cooling is in the works for midweek. Temperatures will instead continue to rise to around the 90-degree mark. Later in the week, a cold front will push toward the area but may struggle to sweep through and usher in less humid and more seasonable air.
Cool air having difficulty reaching the Northeast will be the theme for the remainder of the month.
"While there will be some minor fluctuations in temperature, a persistent ridge of high pressure will keep the warmth and humidity locked into the East through most of the rest of August," added Thompson.
