    Brief, Blinding Snow for Great Lakes, Northeast Highways

    The season's first widespread round of lake-effect snow across the Great Lakes is under way.

    Enough snow can fall in some areas to make roads slippery and bring sudden low visibility for highway travelers.

    Motorists from the Great Lakes to the central and northern Appalachians this weekend are advised to be alert for rapidly changing traction conditions and to allow extra stopping distance between vehicles during the snow showers.

    For a large percentage of the area, this is the first snow event of the season. Roads do not yet have a snow-melting residue on them and can get slippery very quickly.


    Interstate highways in the central Appalachians and downwind of the eastern Great Lakes that can experience the quick-hitting snow squalls through tonight include I-68, I-70, I-80, I-81, I-86, I-90 and I-99.

    The heavily traveled I-95 corridor will be unaffected by the snow showers.

    According to Winter Weather Expert Brian Wimer, "While the event [across the eastern Great Lakes into tonight] will be relatively brief, lasting 12 to 18 hours, it will be the first widespread lake-effect snow of the season."

    On Sunday, light snow from a weak clipper will reach the eastern Great Lakes and whiten some places that avoid accumulating snow earlier this weekend--such as Buffalo and Niagara Falls.


    A storm next week will affect all or part of the eastern third of the nation. The storm will bring not only rain, but the chance of snow on its northern flank and the possibility of thunderstorms in parts of the South.
