Get ready for some serious heat!

June 20, the first day of summer, is expected to roll in with extreme heat. The second day is not expected to bring much relief.

Wednesday will be hazy, hot and humid with a high temperature of 94, according to CBS 2 meteorologist John Elliott. The record high for June 20 is 98 in Central Park, but Elliott said he doesn’t think we will break that — although 94 could tie the record in Newark.

The temperatures will be like those we have not experienced since August of last year. CBS 2′s Lonnie Quinn’s prediction for Central Park on Wednesday is 94 degrees. The AccuWeather RealFeel temperature will be around 100 degrees Wednesday.

On Thursday, it will be very hot and humid with a high near the record of 97, last reached in 1988, according to AccuWeather. The AccuWeather RealFeel temperature will be between 100 and 105.

Records are definitely in jeopardy over the next few days, Elliott said.

Friday won’t be as hot, but it will be humid with clouds and sun. A shower or thunderstorm is possible. The high is expected to be 88.

The New York State Department of Environmental Conservation has issued an air health advisory for Wednesday. It will be in effect from 11 a.m. through 11 p.m.

The New York City Office of Emergency Management will open air-conditioned cooling centers beginning Wednesday.

Scorching heat is most dangerous when the temperature makes a sudden jump, like the 15- to 20-degree leap expected Wednesday and later in the week, CBS 2′s Dr. Max Gomez reported. Heat issues tend to be cumulative and the longer the heat wave, the more likely the health problems as people get dehydrated little by little.

Cooling centers are air conditioned places, such as Department for the Aging senior centers, Salvation Army community centers, and public libraries that are open to the public during heat emergencies.

Cooling centers will be open Wednesday and Thursday. To find the cooling center closest to you, call 311 or visit www.nyc.gov.
