    East Swelters in Record Heat Wave

    "The heat is hard on the very young, elderly and those who work outdoors or in factories."

    Heat that has been building in the mid-South in recent weeks was driving temperatures to record levels at midweek.

    Intense June sunshine combined with building humidity and hot air will push AccuWeather RealFeel® temperatures to between 100 and 110 degrees during the midday and afternoon hours.

    Caution is always advised during hot, sunny days. However, extreme caution is urged due to the intensity of the heat, humidity and June sunshine.

    The heat will be hard on the very young, elderly and those who work outdoors or in factories.

    Never leave children unattended in parked vehicles for any length of time. Heat can build to lethal levels in only a few minutes.


    While the heat is nasty enough throughout the region, the large cities were getting the worst of it as usual.

    Just as urban areas begin to cool down to reasonable levels during the early morning hours, the sun will already be rising on the next day, preparing to broil the cityscape all over again.

    As temperatures climb into the 90s, it can affect train travel. Transit trains must slow down to compensate for slight buckling of the rails as they expand. The extreme heat can also cause some trains to break down.

    Temperatures will top 90 degrees from Burlington, Vt., southward to Boston, Hartford and New York City.

    The heat already reached record levels in Newark, N.J. and in the Baltimore-Washington area during Wednesday afternoon.

    According to Expert Senior Meteorologist Evan Myers, "Temperatures in Washington, D.C. this afternoon were about as high as they were when President Ulysses S. Grant was in Office."

    The record of 102 set in 1874 today was being challenged in the nation's capital.

    From near the Mason-Dixon Line on south today, the 100-degree mark will be challenged on I-95 city thermometers not only in Washington, D.C. but also from Philadelphia and Wilmington, Del., to Baltimore and Richmond.

    This heat wave has already been responsible for sending triple-digit heat into the nation's northern tier. The high in Minneapolis hit 103 degrees on Tuesday, shattering record high of 95 degrees from 2004. Not only was the record high shattered, this was the hottest temperature recorded in the Twin Cities since the thermometer hit 105 degrees on July 31, 1988.

    Although not the first heat wave of the season for the southern mid-Atlantic, it was bringing the hottest weather so far this year for much of the East.


    The hottest it has been in Boston so far was 87 degrees; New York City reached 94 degrees and Washington, D.C. climbed to 99 degrees. All three cities and many others could eclipse this mark by late this afternoon.

    The heat will ease across the Northeast on Friday, but not before a new round of potentially damaging thunderstorms today.

    Beach It!

    Heading to the beach or the public pool is one way to beat the heat if you don't have air conditioning.

    While ocean water temperatures are still traditionally chilly during this part of the season, the surf is running several degrees above normal levels for early June.

    For example, at Sandy Hook, N.J., the water temperature was 71 degrees Thursday afternoon. Typical water temperatures for the middle of June are 63 degrees.

    Westerly winds where bringing the hot air right to some of the beaches Wednesday and today. Local afternoon sea breezes can bring slight cooling.

    Remember to take frequent breaks from the chilly water to avoid muscle cramps and reduce the risk of drowning.

    Only swim in lifeguard-protected beaches.

    Be sure to keep a close eye on young children at all times.
