MONDAY…
A light mix moves in by afternoon. Right now it looks like it might be mild enough for rain near the coast, but a little snow N&W #WCVB pic.twitter.com/DXlFKBCLyh

Zack Green, WBZ: ‘Expecting an additional 2-4″ from now through Friday evening. This is a sloooow stack, not a big thump. Main push will come from ocean enhanced showers during the late afternoon and early evening.’

Crews are able to get a lot of the main drags down to pavement but we still need to take it slow. Temps are below freezing across the board making for really slick conditions.

Coming down at a steady light pace. Dropping visibility across the board. Slow travel times ahead. pic.twitter.com/w9c2a4aweP

Weekend relief? Let’s call it “improvement”.

Flakes wrap up tomorrow morning. Some brighter hours on Saturday afternoon. Sun really takes hold on Sunday but it’ll stay chilly. pic.twitter.com/rJtFUzgfVa

Dave Epstein: ‘Probably some enhancement to the snow later this afternoon/evening and this is when Boston should receive the most snowfall from this nuisance storm’

Accumulation by a thousand snowflakes continues today with the SLOW “storm” finally ending early Saturday morning. You can see areas of precipitation, but lots of holes between. pic.twitter.com/UV0VkHjq0E

Secondary roads will be slick at times this morning… main roads likely wet during the day as the snow is light and road crews keep them well treated. pic.twitter.com/wRcP9apXpv

Send it! Little breezy, passing snow shower tomorrow, but great sledding and skiing weather across New England this weekend. Enjoy! pic.twitter.com/S4QnDMJu5R

Matt Noyes, NBC10 Boston and NECN: ‘Some might refer to today’s snow as ‘snowglobe snow,’ falling nearly continuously but fairly lightly for the most part. While some heavier bursts occur from time to time, I think it gets more interesting later afternoon, evening & early night as wind brings in ocean moisture.’

While I’m expecting generally one to three inches of new snow when you add up today and tonight, I did get pretty specific on @nbc10boston this morning about where is susceptible to higher amounts: Essex County to NH Seacoast, to some extent entire coast where ocean plays a role. pic.twitter.com/3KoUCzo3GA

For those aching for a thaw and wanting to look past this snow…and the fair but chilly weather for the weekend…and the round of rain and snow showers Monday LOL…you saw 40s in the #FirstAlert 10-day I shared on @nbc10boston this AM, and even a 50° forecast high next weekend pic.twitter.com/SHTmf4D5m2
