..A Winter Weather Advisory is in effect from 3 AM to 1 PM Friday for Southern Worcester and Norfolk Counties of Massachusetts and Northwest Providence County Rhode Island for 2-5″ of snow with impacts to the morning commute expected.

The weather pattern will turn active and will be a return to winter for the region over the next few days. Thursday brought high-end Wind Advisory to low-end High Wind Warning criteria to portions of Southern New England. Here are links to summary reports on the wind gusts and wind damage in the region:

Attention turns to a winter storm for the region overnight through Friday Afternoon and the headlines of this message reflect current thinking with upgrades of the Winter Storm Watch areas to Winter Storm Warnings and some expansion of Winter Weather Advisories inland. Key items for this storm event include:

1.) Model trends have maintained a stronger storm intensity but the northern trend was halted and actually slipped a bit further south making the northern fringe of the Winter Storm Warning and Winter Weather Advisory areas tougher to determine proper snowfall ranges as a sharp cutoff in accumulating/heavy snow is possible there.
2.) The highest likelihood for the heaviest snowfall is over the South Coast and Cape Cod and the Islands and into some areas of interior Southeast Massachusetts from about Taunton to Plymouth south and into South-Central Rhode Island. This is currently expected to remain the case for this storm.
3.) Some models are projecting some accumulating snow in the North Shore of Massachusetts later in the day Friday and will be monitored.

It will then become bitterly cold later Friday Night into Saturday with a cold air mass remaining in place through much of next week. Long range models are depicting the potential for a significant coastal storm for the middle of next week but it is too early to get into any details and outcomes could change significantly between now and the middle of next week.

SKYWARN Self-Activation will monitor the winter storm for Friday for snowfall reports. This will likely be the last coordination message for the storm event unless a significant upgrade/change occurs and time allows for an update.
