    Ossining, New York, Saturday morning.

    There were reports of thundersnow from Brooklyn to the Hudson Valley Saturday morning as a relatively rare weather phenomenon hit the New York region.

    Thundersnows--snowstorms in which thunder is heard--are caused when thunderstorms form over cold pool of airs. They are not usually severe.

    Up to an inch of accumulation is possible north and west of New York City, mainly on grassy surfaces.

    The storms are expected to pass by Saturday afternoon. 

    A blast of arctic air is expected to move into the region Tuesday, and it has the potential to bring low temps for the rest of the month.
