Two different, but somewhat related, weather systems will bring us some snow this weekend. There is still some uncertainty, especially with the second storm, but I’ll do my best to break down the forecast below.
Saturday– Occasional bouts of light snow will move through during the day, especially north and west of Boston. Around Greater Boston and on the South Shore some rain will likely mix in with the light snow. Accumulations will be in the dusting-2″ range, again, with the higher totals north and west of the city.
Sunday– A developing storm will scoot up the coastline, and largely stay offshore. The backside of the storm will scrape Eastern New England with some more snow overnight Saturday into Sunday morning. So for this part of the weekend the best chance of accumulating snow is in Southeastern Massachusetts. Winds will also be gusty as the storm passes by, with northwest winds between 30-40 MPH in Eastern Massachusetts. Gusts, especially near the coast, will range from 40-50 MPH.
By the time we reach Sunday afternoon, when the snow tapers off, I’m expecting a widespread 3-6″ for most of Greater Boston and the South Shore. The 6″ amounts will be most likely in communities farthest south. Remember, most of the snow in this area will fall Sunday morning. Slightly more will fall south and east of about Duxbury (4-8″).
Well north and west of Boston I’m expecting 2-4″ of snow by Sunday night. That snow accumulation will come, about equally, from phases one and two of the snow.
This is of course a big travel weekend thanks to February vacation, so stay tuned to further forecast updates. At this point, however, the best chance of seeing travel disruptions would be Sunday morning.
