New Jersey weather: heat index to the top 100 with stifling conditions that will continue for days

The two hottest days of summer thus far are expected on Sunday and Monday with sunny skies and extreme humidity, making it feel like at least 100 degrees on a large swath of New Jersey this afternoon and as warm as 110 on Monday.

Temperatures will rise in the upper mid-90s in most parts of the state, except along the immediate coast, where highs will reach lows in the mid-80s on Sunday, with a heat index of approximately 90 to 100 in those places, the National Weather Service said.

In Bergen, Essex, Hudson, Hunterdon, Morris, Passaic, Sussex, Union and Warren, as well as along the ocean, a heat notice will take effect at noon and last until 8 p.m. on Monday.

The rest of the state will be even warmer and will be under an excessive heat warning for the same period of time.

Newark is forecast to hit 97 on Sunday, still below the record of 100 on July 19, 2013. The peak in Trenton should also hit 97, two degrees from the record of 99 set this date in 1991. It is expected Atlantic City exceeds 87 and will not threaten the record reached 98 in 1963.

At night, temperatures will drop only in the mid-1970s and set for even higher temperatures on Monday, the weather service said in its discussion of the morning forecast.

Monday’s heat index could reach as high as 110 in the corridor between Trenton and Camden, forecasters say. Heat index values ​​as high as 104 are possible on Monday in northwestern New Jersey. Temperatures will hit the mid-upper 90s on Monday and the upper 80s wait near the ocean. There is a threat of thunderstorms in the afternoon, but even if they do develop, don’t expect much relief from the sweltering heat, forecasters say.

Temperatures remain very high on Tuesdays and Wednesdays, also with maximum temperatures in the low 90s both days and the possibility of more warnings and warnings of heat.

While Saturday was also hot, no records were set for New Jersey’s major weather stations. Newark reached 93 at 4:30 pm, well below the record of 104 set on July 18, 2012. Trenton climbed to 92 at the same time: the daily record is 100 in 1953. It reached 84 at the marina. from Atlantic City just before 10 in the morning. The record 99 was set in 1905, according to the weather service.
