    Impacts Heavy snow will make travel difficult late afternoon and early

    this evening in north central NY, with snow and blowing snow

    and icy roads possible later this evening farther south into

    south central NY into northeast PA.

    Dropping temperatures and strong winds tonight will cause

    wind chill temperatures to approach -15 late tonight.

    Strong winds will blow and drift the snow around tonight.

    Wind gusts to 35 mph later this evening into overnight.

    Rapidly falling temperatures will cause a flash freeze

    potential late this afternoon and tonight.

    Could cause very dangerous travel conditions on area

    highways.

    Especially south of where the heavy snow is falling at

    present.

    Risk of multi-car pile-ups.

    People could be stranded if this happens.

    Very cold conditions could make the situation very

    dangerous should this happen. Minor flooding possible in typical flood prone areas.

    Some ice jam issues possible.
