    Oppressive heat and humidity blanketing the Northeast early this week will end after midweek. A cold front will cut into the heart of the heat on Wednesday, but relief will come at a stormy price.

    As searing heat and humidity mix into a perfect thunderstorm cocktail, thunderstorms will erupt along the megalopolis from Boston to New York City, Philadelphia and Washington D.C., on Wednesday.

    The storms will fire first near Erie, Pa., Albany, N.Y., and Portland, Maine, then explode southward reaching the major cities by the late afternoon or evening hours.

    Damaging blasts of wind, blinding downpours and hail bigger than the size of quarters are possible with the most potent storms.

    Anyone with outdoor activities planned for Wednesday should have a watchful eye to the sky if thunderstorms approach. Heed all severe weather watches and warnings and be prepared to take swift action.

    This frightful Wednesday weather will mark the return to a more comfortable air mass for the end of the week, as high temperatures fall into the 80s and humidity values tumble Thursday and Friday.

    Be sure to keep checking back with AccuWeather.com for the latest severe weather information and updates.
