The latest weather guidance I look at seems to be pushing our storm system a bit further east with its forecast track. This could do two things - first is allow enough cold air to push into the area quicker than previously thought & two is focus the highest snow amounts across Central and Northeast Mass rather than Western Mass.
So, it still looks as if rain will overspread the entire area during Friday afternoon and Friday evening. The rain is likely to continue throughout Friday night and Saturday morning.
During Saturday afternoon, the rain is expected to change to snow across all of Western and Central Mass with the snow continuing through Saturday night. It looks like the snow will be light in intensity across Western Mass with a bit more heavier intensity in snowfall across Central Mass where a period of moderate to heavy snow is possible late Saturday afternoon and Saturday evening.
The snow is expected to come to an end during the first part of Sunday morning.
My latest snowfall accumulation forecast map is attached to this post. Please be aware that the forecast of this storm continues to be VERY uncertain and additional changes to the forecast may be needed. It's possible that the storm system may track even further east and if that happens, it could limit the area of heavier snow amounts (3-7") to areas along and inside of 495 with little snow occurring along and west of I-91.
