A messy start to the week will lead to record cold on Thanksgiving Day. Some Monday morning slick spots over interior Central New England were the result of a rather weak disturbance crossing our region. As the last of mixed showers exit stage right Monday midday, leaving cloudy skies and drier conditions for the afternoon, another disturbance is already approaching from the Ohio Valley, set to arrive overnight tonight 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, meaning 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 is unlikely to pick up more than an inch, but those outside of Route 95 to the north and west may see a couple of inches, and outside of Route 495 the potential rises to a few to several inches of snow, with the greatest snowfall expected in Western MA, Southern VT, Central/Southern NH and Southern ME 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, respectively, ushering in the coldest air of the young season for Thanksgiving Day, when highs are only expected to reach 20-25 degrees and wind chill values will hover either side of zero, putting Thanksgiving Day road races and football games in jeopardy, though moderation is expected especially by Saturday in our exclusive Early Warning Weather 10-day forecast.
