Unsettled Weather as Air Masses Battle it Out

    High pressure to our east and low pressure to our west are creating a southwest air flow that is bringing milder temperatures into Southern New England.

    At the same time, there is a cold air mass dropping from Canada to northern New England and it will trigger snow showers overnight along the Canadian border, the Northeast East Kingdom, Coos County in New Hampshire and northwest Maine.

    Expect 1 to 3 inches of snow accumulation. As the warm air mass to the south and cold air mass to the north meet in central New England on Wednesday, a boundary line will set up, and wherever that boundary sets up will determine a big difference in temperature for Wednesday.

    We are thinking the front will set up shop from coastal Maine to southern New Hampshire and toward Bennington and Windham counties in Vermont. North of the front, the wind will be coming in from the northeast, and it will be cool and raw with some snow showers. South of the front, it will be mild with temperatures in the upper 50s to low 60s and a few rain showers.

    Overnight Wednesday night, the front will continue to sag south into southern New England, bringing chillier air into the region. Along the front, showers will redevelop, and if temperatures fall just a couple of degrees below the freezing point, we could see a few pockets of freezing rain across northern Massachusetts, southern Vermont and southern New Hampshire on Wednesday night into early Thursday morning.

    On Thursday, the front travels back north, but it is swept away Thursday night by a storm system traveling through the Great Lakes towards New England. This will bring showers once again on Thursday night and periods of heavier rain Friday morning and early afternoon.

    I can’t rule out the possibility of an embedded thunderstorm Friday morning. The storm is rather progressive and should move out to sea by Friday late afternoon. High pressure will then build in again, bringing drier conditions to New England for the weekend.
