Sunday Afternoon Storm Update

Good afternoon!

Precipitation Types

Snow. There is a slight chance of a mix at the immediate NE MA coast closer to Boston this afternoon.


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.


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!

Hello! I'm Nathan Coram, a 20 year old meteorology student and weather geek, and am in my junior year at UMass Lowell as a meteorology major. I am the current Vice President of the UML American Meteorological Society Local Student Chapter. Prior to at UML, I attended the Dracut school system for my K-12 years, having graduated from Dracut High in 2018. I first got into weather with the December 2008 ice storm, which knocked out my electricity for 4 days. I had no idea how it could be raining and becoming ice immediately, and how rain can knock out power. (Now I do - warm layer aloft, cold air at surface). But I didn't really get into it until the heat of July 2010 and specifically a few severe weather events during that month, followed by the year 2011, which featured several high profile weather events. Since then I have had a growing interest, and am hoping to make it into the meteorology field, preferably with NOAA/NWS. But for now, I'm blogging here on Dracut Weather (also on Twitter and Facebook), helping with the UML Weather Center social media, and tweeting about the weather on my own account as well. Thanks for visiting!
