The Winter Storm Watch has been expanded through all of eastern Massachusetts, this includes the Boston to Providence corridor. Snow will redevelop Saturday morning and then overspread the Commonwealth Saturday afternoon. Snow will taper off Saturday night from west to east.
The National Weather Service (NWS) today expanded a Winter Storm Watch through Saturday, forecasting gusty northeast winds up to 40 mph along the eastern Massachusetts coast which could result in considerable blowing and drifting snow along with poor visibility. The NWS also warned about treacherous travel conditions late Saturday afternoon and evening.
If this trend continues, the Winter Storm Watch may need to be expanded slightly farther west into central Massachusetts.
There is a moderate risk (30-60% chance) of 6+ inches of snowfall through eastern Massachusetts. The risk is higher across Plymouth County into Cape Cod and the Islands, where snow accumulations of eight to 15 inches are possible. The steadiest and heaviest snow will likely fall late Saturday afternoon and evening. Snowfall rates of up to an inch per hour are possible with potentially heavier snowfall rates across southeast Massachusetts. The latest forecast trends have been for a stronger ocean storm and tracking closer to the region.
