Moisture feeding from the south will bring first snow and then a changeover to freezing rain and all rain across New England. This slow-moving storm could result in sizable snow, ice and rainfall totals, making it potentially the most impactful storm so far this winter.

A mix of snow and rain is coming to Massachusetts Thursday and there's another storm in the forecast for the Boston area this weekend.

Storm Watch is in effect for all of western Massachusetts from 1 p.m. Saturday until 7 p.m. Sunday for accumulating snow and a wintry mix.

According to Meteorologist Shiri Spear’s latest weather blog post, the storm looks like it will move in between about 8 p.m. and 11 p.m. on Saturday night, with the heaviest snow falling from midnight through 7 a.m. on Sunday.

Snow is expected to stop in Worcester and the western part of the state before 9 a.m., gradually moving out of eastern Massachusetts by noon. Essex, Suffolk and Middlesex counties in the northeast part of the state may see snow showers through 5 p.m. on Sunday.

The snow arrives between 8 a.m. and 10 a.m. Thursday from southwest to northeast. It will only last a few hours in most areas (longer the farther north you live). The majority of the snow accumulation will be over by early afternoon.

In the Northeast, sleet and freezing rain may occur, affecting driving conditions and possibly creating power outages.

Following a flurry of inclement weather this month, swathes of the country could see more wintry impacts next week.
