Good afternoon!
Precipitation Types
Snow. There is a slight chance of a mix at the immediate NE MA coast closer to Boston this afternoon.
Timing
Snow is overspreading the region as we speak, and will become gradually heavier. Heavy snow will be ongoing this evening, then a bit of a lull is possible before more heavy snow goes on late tonight through mid to late morning Monday before ending.
Impacts
Heavy snow will make travel very dangerous. Strong winds may contribute to some power outages and periodic blizzard conditions. Schools throughout the area are near-certain 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, as thermal issues will mean most of their snow will come via comma head backlash snow at the end.
Now for the map… **Map updated this evening**
Again, the numbers could change (although they are less likely to see big changes in northern MA and on northward) so stay tuned.
Have a good day!
