The National Weather Service says a high impact winter storm beginning Sunday afternoon into Tuesday.
Some snow has begun falling and will continue into early Monday. As warmer air intrudes aloft, precipitation changes to sleet, then to a sleet/snow mix in northern MA, and to plain rain in southeast MA for the overnight hours.
By daybreak Monday, snow/sleet accumulations of 6-8" possible in western and northern MA with approximately 4-6" in Springfield and interior Essex County, with 2-5" elsewhere, except less than an inch on Cape Cod/Islands and near the immediate coast in southeast MA.
Early in the morning on Monday, rain will be occurring in much of eastern MA, with a mixed bag elsewhere. However, everything will change back to snow from west to east. Less snow is expected than what occurred on the front end Sunday, but there still could be several inches in some locations. This may be dependent on where localized bands of heavier snow set up.
The NWS is expecting a widespread 8 to 10 inches over much of interior MA with as much as a foot possible in the higher Worcester hills and 12 to 17 inches in the east slopes of the Berkshires.
Amounts drop off rapidly as one heads southeast, with 3 to 5 inches in Plymouth and less than an inch on Cape Cod and the Islands.
