Temperatures may hit 90 F for the first time this season in New York City, Philadelphia and many other cities in the Northeast and the Ohio Valley during the middle of next week.
If you have been holding out because of cool conditions so far this season, now may be the time to put the air conditioner in the window or get your central air tuned up.
According to AccuWeather.com Long Range Expert Paul Pastelok, "A piece of the high pressure area responsible for the heat in the Southwest will break off and drift into the Eastern states next week."

Since 2000, the latest New York City has hit 90 was on June 24, 2003, when the high was 93.
The latest Philadelphia has hit the 90-degree mark was June 23, 2003, when the high was 92.
Other cities in the Ohio Valley and Northeast that have not yet hit 90 this year and may do so next week include Pittsburgh; Cincinnati; Cleveland; Indianapolis; Louisville, Kentucky; Harrisburg and Scranton, Pennsylvania; Hartford, Connecticut; Providence, Rhode Island; and Atlantic City and Trenton, New Jersey.
"The heat next week will be accompanied by moderate to high humidity," Pastelok said.

AccuWeather RealFeel® temperatures may run 10 degrees higher than the actual temperature for a number of hours during the midday and afternoon during the peak of he hot weather.

Boston, Detroit, Chicago and other northern tier cities will be on the northern fringe of the heat but could break into the hot air and touch 90 for a short time. While Chicago did reach 90 on June 1 this year, Boston and Detroit have stopped short of the mark so far.
The core of the heat will settle over the Ohio Valley, the mid-Atlantic and southern New England next Wednesday.
"Monday to Tuesday of next week will be the transitional days as a warm front lifts slowly across the area from southwest to northeast," Pastelok said.
Some locations may squeeze out two to three days of 90-degree temperatures. While 90-degree highs are fairly routine in the Deep South in the summer, three days in a row of 90-degree highs are considered to be a heat wave in the Northern states.
Locally heavy, gusty thunderstorms can occur part of the region prior to the arrival of the heat Monday into Tuesday then on the northern rim of the heat as it reaches its peak.
"Late next week, the heat will be chopped down in stages from northwest to southeast as a series of fronts drop in from Canada," Pastelok said. "The core of the heat will then settle back over the Southwest states late next week."
