New Yorkers should brace themselves for a sweltering weekend ahead, with temperatures set to soar into the high 90s in some boroughs. According to detailed forecasts provided by the National Weather Service, Manhattan can expect to see a high of 89 degrees today with sunny skies, while Friday's temperatures could climb to a high near 97, coupled with heat index values as high as 105. Brooklyn, Queens, the Bronx, and Staten Island are also anticipated to experience similar scorching weather.

Alongside the torrid heat, the region also has to prepare to face scattered showers and thunderstorms. Manhattan, for instance, could see a 30 percent chance of these conditions mainly after 5 pm on Friday. The boroughs of Brooklyn, Queens, and the Bronx have a similar forecast for potential thunderstorms, while Staten Island’s likelihood for thunderstorms peaks at a 30 percent chance after 5 pm on Friday, according to respective forecasts from National Weather Service for Brooklyn, Queens, the Bronx, and Staten Island.

A Hazardous Weather Outlook report has been released, highlighting potential widespread hazardous weather events that may reach National Weather Service warning criteria, including the probability of "isolated to scattered severe thunderstorms," according to the National Weather Service.

People living in southern Connecticut, northeastern New Jersey, and southeastern New York are advised to remain vigilant during this period of oppressive heat. With the Heat Advisory still in effect, individuals are urged to limit outdoor activity and to stay hydrated to avoid heat-related illnesses. The advisory reminds citizens that "Isolated to scattered severe thunderstorms are possible Friday afternoon with damaging wind gusts the primary threat," which could pose additional hazards such as power outages and fallen trees.

As the weekend progresses, temperatures are expected to slightly decrease, with forecast highs hovering in the upper 80s to low 90s across the New York City boroughs. Nonetheless, the possibility of rain and thunderstorms persists into Sunday. But by Monday, the weather is predicted to start calming down with sunnier days ahead. Sunday still has a 50 percent chance of showers and thunderstorms after 2 pm, with Monday looking mostly sunny, hopefully signifying a respite from the turbulent weather patterns experienced over the weekend.
