    A messy start to the week will lead to record cold on Thanksgiving Day.

    Another disturbance is already approaching from the Ohio Valley, set to arrive overnight Monday and last through Tuesday early afternoon.

    Like its predecessor, this new storm system won’t be exceptionally strong and will be moving through air marginal for rain or snow. This means a rain/snow line is likely to set up across Central and Northern Massachusetts as precipitation begins lightly late Monday evening and intensifies for the Tuesday morning commute to midday.

    Due to a mix with rain, the immediate Boston Metro-area is unlikely to pick up more than an inch. Those outside of Route 95 to the north and west may see a couple of inches.

    For residents outside of Route 495, the potential rises several inches of snow, with the greatest snowfall expected in Western Massachusetts, Southern Vermont, Central and Southern New Hampshire and Southern Maine, where the entire event should feature snow rather than rain.

    Significant wind and waves aren’t expected with this storm, so the biggest impact is on local travel. An arctic cold front approaches Wednesday, triggering afternoon and evening scattered snow squalls from north to south.

    The coldest air this week will likely be Thanksgiving Day when highs are only expected to reach 20 to 25 degrees. Wind chill values will hover either side of zero, putting Thanksgiving Day road races and football games in jeopardy.

    Don't fret yet! Moderation is expected by Saturday in our exclusive Early Warning Weather 10-day forecast.
