3”-5” – Area in between I-495 and Rt 128 including a large part of Essex county and eastern Middlesex county (a slightly heavier snow here)

1”-3” – The immediate coastline from Cape Ann to Cape Cod will see 1-3″ of snow, much of which will be washed away on Cape Cod as the change to rain occurs.

The good news, no real wind or coastal concerns with this storm, main impact is simply snow.

What’s Next:

Well, it is only mid-January and this looks like it will be our 4th significant snowstorm for the region, likely pushing Boston close to 30” already (about a foot above the average for this date). Front-loaded winter? Yep.

However, January thaw part 2 arrives this weekend with highs at least in the 40s (if not 50). And, our next storm system looks like rain early next week. Finally, the overall pattern through the remainder of January is for a ridge in the eastern U.S. and a trough in the West (this is the opposite of where we have been thus far this winter). So the likelihood for more significant snow in the next 1-2 weeks is relatively low.
