While escaping high heat over the Fourth of July weekend, the Northeast will once again see temperatures soar into the 90s F at midweek.

"Summer will awaken from its slumber in the Northeast this week," AccuWeather Forecasting Intern Brady Harris said.

A dip in the jet stream kept hot and humid air suppressed from most of the Northeast over the holiday weekend, but summer conditions will surge back as the jet stream lifts to the north.

In the wake of the soaking for the mid-Atlantic on Monday, temperatures will steadily rise across the Northeast Tuesday into Wednesday.

Midweek highs will be in the upper 80s and lower 90s in many areas, according to Harris.

Highs on Wednesday will crack the 90-degree mark throughout the I-95 corridor from Washington, D.C., to Philadelphia to New York City to Boston.

It will mark the first 90-degree day for New York City and Boston since the start of the Memorial Day holiday weekend.

Higher humidity, which will be most noticeable over the mid-Atlantic, will create even higher AccuWeather RealFeel® temperatures. Such values will approach or surpass the century mark in the I-95 corridor of the mid-Atlantic.

Due to the recent lack of heat and humidity, the hot weather at midweek may put an extra strain on residents.

Be sure to drink plenty of water, wear light-colored clothing and avoid strenuous activities during the midday and afternoon hours (the hottest times of the day) to prevent suffering from a heat-related illness.

There will be no cooling thunderstorms to offer heat relief, which is good news for those who want to head to local swimming pools, lakes or beaches.

The heat, however, will further dry out areas that are in need of rain. The majority of the Northeast was at least abnormally dry, according to the United States Drought Monitor's report from last Thursday.

Most of New York State, as well as northern and central New England will miss out on rain from Monday to Tuesday.

Thunderstorms will return to the Northeast later in the week, knocking down temperatures slightly. However, it will still be warm and remain sticky outside of northern New England.
