    Temperatures more typical of the middle of July will return to the northeastern United States by midweek.

    As an area of high pressure swings offshore, the door will open for temperature and humidity levels to trend upward.

    On Tuesday, many communities in the eastern Great Lakes will record highs in the lower 90s F.

    At midweek, widespread highs in the upper 80s and lower 90s are expected throughout the Northeast.

    The greatest departures from normal and most numerous 90-degree readings will likely occur from the eastern Great Lakes to New England on Wednesday.

    "Despite the upcoming heat, very few places will challenge record highs, since many record temperatures are in the upper 90s to low 100s this time of the year," according to AccuWeather Senior Meteorologist Alex Sosnowski.

    On Wednesday, Rochester, New York, could endure its highest temperature since July 2012, if the temperature reaches 97, according to AccuWeather Meteorologist Bill Deger.

    Later this week, the heat will intensify along the I-95 corridor of the mid-Atlantic and southern New England. However, the warmth will be gradually trimmed across the interior.

    Humidity and other conditions will cause AccuWeather RealFeel® Temperatures to be even higher.

    RealFeel temperatures during the second half of this week will climb to or past the century mark across parts of the mid-Atlantic and potentially southern New England and New York State.

    Residents should take the necessary precautions to avoid sustaining a heat-related illness. Never leave a child or pet in the car, even if it is for a short time.

    As the week progresses, a mosaic of spotty thunderstorms will develop. The storms will be most common during the afternoon and evening hours.

    The majority of cooling thunderstorms, along with needed rainfall, will occur across the interior of the Northeast during the second half of the week.

    While some locations can be hit with a storm nearly every day from midweek on, still a few locations may escape the week with little or no rainfall.

    A cold front will arrive on Friday and could trim the steamy air for the weekend.

    Prolonged heat relief will not be the theme for the remainder of July and even into August in the Northeast, according to AccuWeather Meteorologist Evan Duffey.

    In the Northeast, "The heat will likely be a bit of in and out through the summer with quick-moving systems bringing temperatures well above normal for a few days before a day or two of relief," he said. "Then temperatures will begin to rise again."

    For areas that miss out on the cooling thunderstorms this week, Duffey also provided positive news.

    "We feel that there is a good chance for rainfall to begin reaching more places as we head toward the end of the month," he said.

    "We do not expect at this time for there to be enough rain to bring the entire Northeast out of its developing drought, but it may be enough to prevent conditions from deteriorating further."

    The majority of the Northeast is experiencing at least abnormally dry conditions, according to the United States Drought Monitor.

    Severe drought conditions have developed in parts of Massachusetts and southern New Hampshire.
