    Cool Trend in Northeast, Midwest to End

    By By Brian Lada, Meteorologist
    August 21, 2013, 5:15:54 AM EDT

    It was an unseasonably cool weekend across the Northeast and Midwest with the trend of cooler temperatures expected to come to an end this week.

    Temperatures have been more consistent with that of mid-September rather than mid-August from Boston through St. Louis and up into Minneapolis.

    By mid-week, these below-normal temperatures will come to an end as warmer, more humid air ushers in from the Plains.

    Below-normal temperatures are not foreign to the Midwest and Northeast as low humidity and unseasonably cool temperatures have held strong over these regions dating all the way back to July 24th.

    Since then, a dip in the jet stream has allowed for cooler, less humid air from Canada to settle into this portion of the United States.

    Temperature Departures From Normal Since July 24, 2013

    City

    (Degrees F)
    New York City

    Detroit
    -4.7
    Chicago
    -4.6
    Minneapolis
    -3.6
    St. Louis
    -5.7

    During this trend of cooler temperatures, Minneapolis and Detroit have only had two days with temperatures above normal.

    Not only have temperatures averaged below normal, but new record lows have been set in many towns across the Northeast. A majority of these records were set on Aug. 15th where low temperatures dipped into the upper 30s in some spots.

    Some towns that set record lows on this date include Williamsport, Pa., Elmira, N.Y., Sussex, N.J., Youngstown, Ohio, and Lynchburg, Va.

    This cooler weather has been welcomed by some by providing a break from the summer heat, while others have found it to be unwelcome.

    Cooler temperatures have deferred people away from beaches and water parks, foiling some vacation plans made months in advance.

    With warmer, more summerlike air building in this week, beaches should have an uptick in attendance before summer comes to an end in September.
