    Northeast Frost, Freeze Friday Night

    Another chunk of cold air and the potential for a killing frost and freeze are aiming for the United States and southern Canada.

    This particular batch of air will aim more to the east, rather than to the south.

    The rather round-shaped area of cold air and conditions capable of producing near- or below-freezing temperatures closest to the ground will have its maximum effect Friday night into Saturday morning. The cold push will follow a couple of potential snow events along the U.S./Canada border.

    This time, the risk of garden-ruining temperatures could reach the northern and western suburbs of Washington, D.C., Baltimore, Philadelphia, New York City and Boston, as well as some of the normally colder spots south and east of these cities.

    The most recent push of cold air was centered over the Plains and Midwest.

    The frost/freeze was nullified by a series of weak storms running northeastward along the Atlantic coast. While the storms made for chilly daytime temperatures and a a cold rain, cloud cover from these storms prevented temperatures from dropping off substantially at night.

    **Prior to the large area of frosty conditions Friday night, a small area of high pressure will bring a frost and freeze to portions of the central Appalachians Wednesday night into Thursday morning.**
