Snow will move into the region starting after midnight tonight and overspreading much of the Commonwealth by the start of the morning commute. Snow may be heavy at times toward daybreak and into the morning before tapering off from west to east Friday afternoon. There will be a sharp cutoff to the snowfall from south to north over a very short distance. Snow bands associated with this storm will be very narrow, resulting in wide variability in the amount of snowfall received.
Total snowfall along and north of the Mass Pike will range from a dusting to 3 inches, with higher amounts to the south and east. Southeastern Massachusetts will see 4 to 8 inches of snow with localized totals of up to 10 inches, with the highest amounts most likely to fall along the south coast and the Cape and Islands.
