    Snow, Icy Mix Expanding Over More of the Northeast

    Heavy snow from the Washington, D.C., to the Philadelphia area is giving way to an icy mix, while snow and ice spread across more of the Northeast through Monday.

    A band of heavy snow spent Sunday spreading from north-central West Virginia to Philadelphia and southern New Jersey, crossing the northern suburbs of Washington, D.C., and Baltimore in the process.

    As of 8 p.m. EST Sunday, Newark, Del., sat at the top of the snow's totals list with 12 inches.

    A nightmare unfolded for travelers as numerous accidents resulted, while flights were cancelled and delayed.


    While the heavy snow has eased, the winter storm is not done impacting the Northeast.

    Travel will remain treacherous from Washington, D.C., to Philadelphia as the snow continues to transition to an icy mix through Sunday evening.


    At the same time, snow will continue to press northward toward Albany--crossing New York City--Sunday evening as an icy mix also keeps travel slick from Pennsylvania to the I-81 corridor of Virginia.

    The snow will spread over more of New York and central and southern New England late Sunday night, as the transition to a bit of ice also comes northward to around Albany.

    On Monday, the wintry mess will focus over much of New York and interior New England. However, there will still be some freezing rain across central Pennsylvania.


    North of Philadelphia, snow amounts will mainly be on the order of a coating to 1 inch along the I-95 corridor from New York City to Boston and Portland, Maine.

    A zone of heavier snow, with totals average 3 to 6 inches, will develop over the St. Lawrence Valley.

    As the storm moves along through Monday many locations over the interior will also transition to plain rain. However, there will continue to be a few pockets where an extended period of ice occurs with treacherous driving conditions.

    One area of ice is likely to focus in the I-81 corridor of western Virginia.


    According to AccuWeather.com Senior Meteorologist Kristina Pydynowski, "Enough ice may accrue on trees and utility lines in both areas to block roads and cause power outages."

    Only if more sleet were to fall instead of freezing rain would there be less serious damage and disruption.

    The storm will also put down snow and freezing drizzle across the Midwest and rain in the South.

    Road conditions are likely to improve from Washington, D.C., to New York City by Monday morning as rain takes over, but travel may be slow, slushy and slippery around Boston in the early hours. Flight delays due to rain and low ceilings may linger through much of the day Monday in the I-95 Northeast.
