Nor'easter to Bring More Than Half a Foot of Snow to Some Parts of New England

A Winter Storm Warning is in effect for much of the region through Friday morning



    Heavy Snow on the Way

    Today (Wednesday): Partly to mostly cloudy and cool. Highs in the 30s north to near 40 south. Overnight Wednesday Night: Variable clouds, lows near 30 south, 20s north. Thursday: Rain and snow south, all snow north. Highs in the upper 20s north to upper 30s south. (Published Wednesday, Dec. 28, 2016)

    Find your shovels — for some in New England, snow is on the way.

    The mild surge of warm damaging wind from early Tuesday is on the way out. Seasonable sunshine is here for our Wednesday. But Thursday is looking more and more interesting.

    A coastal storm will be developing east of Montauk, New York. Low pressure will rapidly develop as it moves north, hugging the coast. Winds will shift to the northwest, which will help establish the cold air across interior New England.

    A Winter Storm Watch is already in effect for all of New Hampshire and Maine, most of Vermont, west of Route 128 in Massachusetts and the Litchfield Hills in Connecticut. Areas under the watch will likely see a significant snowfall.

    Precipitation will begin Thursday afternoon. Weather conditions will rapidly deteriorate during the Thursday evening commute. As this storm rapidly intensifies, snowfall rates may exceed two inches an hour, causing white-out conditions.

    Low pressure will form on the front and intensify rapidly as it moves from Long Island to Portland, Maine on Thursday and Thursday night.

    The morning should start cold and dry, with snow developing in western New England by mid-day. Rain is likely along the coast in southern Connecticut.

    Snow and coastal rain will overspread New England rapidly during the afternoon, so it will be a high impact for the evening commute.

    The rain-snow line will be within 20 miles of Boston, though we will have to fine-tune as it gets closer.

    Snow may be very heavy Thursday evening and overnight, ending as the sun comes up Friday morning.

    Accumulations in excess of 10 inches are likely where it stays all snow, especially in the higher elevations from central Massachusetts northward.

    Rain at the coast will likely end in a period of snow, with a coating possible all the way to Cape Cod.

    Wind, initially not a factor, will increase from the northwest after the storm goes by, so it's a windy and cold Friday.

    High temperatures will be in the 20s to low 30s with winds gusting past 40 mph during the morning.

    We end up with mostly sunny skies by Friday afternoon. The early call on our weekend is for increasing clouds Saturday with a chance of snow in northern New England by sunset. For southern New England it may be a little bit snowy or rainy as we ring in the new year at midnight.

    Sunday looks like a mixture of sun and clouds and a chance of flurries with highs in the 30s.
