    Play video A look at Wednesday's weather across the Northeast.

    Isolated strong-to-severe thunderstorms may impact evening plans across portions of the mid-Atlantic on Wednesday.

    Widespread severe weather is not anticipated, but a few stronger thunderstorms could produce wind gusts over 45 mph, which would produce wind damage in spots.

    Cities that may be impacted by gusty thunderstorms include Philadelphia, Pittsburgh and Harrisburg, Pa., Baltimore, Md., and Washington, D.C.

    Travelers along Interstate 95, 81, 83 and 76 should be prepared for rapidly changing weather conditions, including heavy downpours and strong, gusty winds.

    A cold front will interact with warm, moist air, sparking scattered showers and thunderstorms from the Ohio Valley east into the mid-Atlantic through early tonight.

    Despite a recent increase in moisture in the region, the air mass still will not be humid enough to support widespread strong-to-severe thunderstorm development.

    People with outdoor plans across the mid-Atlantic Wednesday evening should watch for a changing sky and head indoors if thunder is heard.

    The front moving through is the same one that helped produced the wild temperature swings over the Plains states over the past couple of days.

    The cold front leading to the thunderstorms through early Wednesday night will slowly drift southward on Thursday, bringing drier weather to much of Pennsylvania. However, the front will still be close enough to spark a few thunderstorms around Baltimore, Md., and Washington, D.C.
