From the Massachusetts Emergency Management Agency (MEMA):

Dangerously Cold Weather and Upcoming Coastal Storm on Thursday (Info as of 10:30 AM on 1/2/18)

Wind Chill Advisories have ended, but very cold weather is also forecast for this evening and the coming days.

Additionally, the National Weather Service (NWS) is forecasting a strong coastal storm on Thursday that will bring accumulating snow across the entire state, with the eastern half of the state seeing the greatest amounts. Strong and possibly damaging winds are also expected, with the greatest threat on Cape Cod and the Islands.
• Winter Storm Watches are in effect for all of RI and portions of eastern MA.
• Snow will overspread the region from southwest to northeast after 2 am Wednesday night/Thursday morning and last most of the day on Thursday. On the Cape and Islands, the precipitation may start as rain but it likely will transition to snow by Thursday evening. Snow may be light initially but will increase in intensity during the day. Travel may become difficult due to poor visibility and snow covered roads. Blowing and drifting snow is also possible.
• All of the state will see accumulating snow, with the greatest amounts in eastern MA (excluding the Cape and Islands). Most likely snowfall totals will be 3” to 4” in central and western MA, up to 3” on the Cape and Islands, and 5” to 8” elsewhere in eastern MA. However, there is a low risk of 10” to 12” of snow across much of the state if the track of the storm shifts to the west.
• West winds will increase Thursday morning, with the strongest winds expected from late morning into the afternoon. Most of the region can expect gusts of 25 to 35 mph, but gusts up to 55 mph are forecast on Cape Cod and the Islands.
• Mid-Day high tide could result in minor to moderate coastal flooding for northeast facing beaches. Currently anticipate surge between 2-3 feet.

POSSIBLE IMPACTS:
• Snow may cause slowed commutes, hazardous travel conditions especially on untreated bridges, overpasses, and secondary roads.
• Strong wind gusts may cause loose objects to become airborne; scattered tree damage, isolated power outages, and possible structure damage.
• Minor to moderate areas of coastal flooding may cause significant beach erosion and areas of coastal flooding.

There is still some uncertainty on the exact track of the coastal low. If storm trends farther west then more wind and higher snowfall amounts are possible. If it moves a bit farther east than wind and snow will be less.
