Snow. There is a slight chance of a mix at the immediate NE MA coast but this is not likely. Also, some freezing drizzle is possible early tomorrow morning.
Snow begins as a more moisture-laden snow mid to late morning tomorrow and continues through the rest of the day and overnight, gradually becoming fluffier in nature but still falling heavily at times. This continues through Monday mid-morning, at which snow begins to taper off and then leave.
Heavy snow will make travel very dangerous. Strong winds and a period of wetter snow may contribute to some power outages. Schools throughout the area are likely to be closed on Monday. Whiteout conditions at times will lead to near-impossible travel of any type at times.
Amounts and Uncertainty
Certainty is quite high in northern and northeastern MA, VT, NH, ME, etc. The only issue to sort out is likely to be one of where exactly the heaviest snow band sets up. The highest totals will be in coastal Maine, but the heaviest band for us will probably be in interior northeast MA and interior southeast NH, right in the Lawrence-Lowell-Nashua-Manchester area – the Merrimack Valley.
Certainty is much, MUCH lower near and south of the Massachusetts Turnpike. While this blog tends to focus more on areas north of the Pike, I’ll briefly discuss areas south of it now: Amounts could change very significantly south of the Pike dependent on precipitation type (which will be an issue there), exact thermals, etc. As a result, I have gone very conservative on my map south of the Pike.
Now for the map…
Again, the numbers could change (although they are far less likely to see big changes in northern MA and on northward) so stay tuned.
Have a good day!
