From the National Weather Service:

Powerful Winter Storm Sunday into Monday (Info as of 11AM on 2/11)

The National Weather Service (NWS) has issued a Winter Storm Watch for the majority of the Commonwealth for a powerful winter storm Sunday into Monday. This storm has potential for significant heavy, wet snowfall, strong to damaging northwest winds, and minor - with pockets of moderate - coastal flooding along north and west-facing shores.

SNOWFALL: Areas north and west of the Mass Pike may see 8-12 inches of snow; areas north of Rte 2 may see 12-18 inches; eastern and southeastern Massachusetts may see 2-8 inches. Snowfall is forecast to begin between 10 am to 1 pm Sunday, with the potential for precipitation starting a wintry mix with sleet, freezing rain, or rain in areas, and transitioning to snow. The snow may lift north briefly Sunday night, but will return Monday morning with more intense snowfall from west to east, with possible 2 to 4 inches of snowfall per hour rates. Snow will taper off Monday afternoon/evening. Blowing and drifting snow will reduced visibility to a 1/4 mile or less at times.

WINDS:
There will also be strong to damaging winds along the coast, Cape and Islands, increasing the potential for scattered power outages. 
The strongest winds are expected to occur Monday midday into the afternoon. Sustained winds of 20 - 25 mph are expected inland, with 35-45 mph along the coast, Cape and Islands. Winds could gust up to 45 mph inland and up to 65 mph on the outer Cape and Island.

COASTAL FLOODING:
North/West facing shorelines of east coastal Massachusetts, as well as the north coast of Nantucket, may see minor to moderate coastal flooding around the Monday midday high tide.

IMPACTS:
• Snowfall may result in poor visibility and difficult travel Sunday/Monday
• Potential impacts to Monday morning commute
• Power outages with downed limbs and power lines due to the weight of the snow
• Shore roads may become impassable due to coastal flooding around Monday midday high tide
• Beach erosion on north-facing shores

There is still uncertainty in the forecast at this time.
