3 To 6 Inches Of Snow Accumulation Is Expected Sunday Night Into Monday: It looks quite likely that Western and Central Mass will see accumulating snow that starts late Sunday afternoon and continues through all of Sunday night and into the day on Monday. A moisture packed area of low pressure is expected to develop just off of the coast of the Mid-Atlantic States on Sunday afternoon and head northeastward passing to the east of Nantucket late Sunday night. On Monday, this low pressure system is expected to head for Nova Scotia. While this type of track is a bit too far east to produce a heavy amount of snow across the area, it is expected to be just close enough to bring enough snow to plow on Sunday night into Monday. With that said, there are some flies in the ointment with this storm that could lead to both less snow than what I am forecasting right now and more snow than what I am forecasting. On one hand, it is possible that this storm could head even further east and also wait to strengthen. If this occurs, it would mean a much lighter snowfall on the order of an inch or two. On the other hand, there is the possibility that this storm could strengthen before it reaches the area near Nantucket and also strengthen more than what’s expected right now. This would lead to a heavier snowfall on the order of 6 to 10 inches of heavy, wet, sticky snow instead. Here Are My Thoughts As Of Right Now: Snow will likely overspread Western and Central Mass between 4 pm and 7 pm Sunday. The snow is then expected to continue throughout Sunday night into Monday morning. Snow should come to an end by mid morning Monday across Western Mass, however, it may continue to snow into early Monday afternoon across Central Mass before ending later Monday afternoon. As For Snow Amounts, my thinking right now is for a total of 3 to 6 inches of snow accumulation across Western and Central Mass. I think the lower end of the scale (3 inches) may occur in the Pioneer Valley of Western Mass while the upper end of the scale (closer to 5 or 6 inches) may occur in the Worcester Hills and the Berkshires where some lift and extra moisture may be produced by orographic lift. This is expected to be a wet, sticky, heavy snow with snow covered and slippery roads expected on Sunday night into Monday morning. In addition, since this is expected to be a wet snow, there is the possibility for isolated power outages in the Worcester Hills and the Berkshires where closer to 5 to 6 inches of snow is possible.
I will continue to have updates on this storm, so keep checking back!
