Massachusetts residents can anticipate little relief from the rain and snow this week, as another storm is set to arrive in the region Wednesday afternoon, making for what could be a messy evening commute.
That storm is expected to be similar to other recent weather events in the state, with a mix of rain and snow in the forecast across Massachusetts, said Bill Simpson, a meteorologist with the National Weather Service.
Snow is expected to move into Greater Boston between noon and 2 p.m. on Wednesday, said Alan Dunham, another weather service meteorologist. Forecasters expect it to snow for most of the afternoon, bringing about an inch to the area, Dunham said, before it mixes with rain and then transitions solely to rain between 10 p.m. and midnight.

Areas north of the Massachusetts Turnpike and west of Interstate 495 have the best chance for accumulating snow on Wednesday, Simpson said, while communities closer to the coast are likely to get lesser amounts.
“As was this past storm, the greatest snow would be up in the Route 2 corridor into northwest Massachusetts,” Dunham said. “The further southeast you go toward Cape Cod, the less snow you’ll see.”
In the Boston area, temperatures are expected to be in the low 30s — not below freezing — so any kind of accumulation would amount to slushy surfaces during the afternoon and into the evening commute, Simpson said. Drivers north and west of Boston on Route 128 and I-495 are likely to see the greatest impact on their commutes, Dunham said.
But there could be some periods of accumulating snow, Simpson said, because heavy snow could bring the temperatures down and allow for it to accumulate.
Forecasters said online Wednesday’s temperatures will be key to determining how much snow the region will get, though Western Massachusetts and areas of higher elevation will see more of the white stuff.
Temperatures will rise overnight Wednesday into Thursday into the mid-40s in Greater Boston, Dunham said. Thursday will be cloudy and rainy with a high of 50 degrees in the morning. Temperatures will drop into the low 40s in the afternoon. The Boston area will likely see an inch of rain through Thursday afternoon, when the storm is expected to end.
Early indications are that the storm Wednesday will be windier than Monday’s, Simpson said.
The Cape and Islands and the South Coast could see wind gusts over 40 miles per hour on Wednesday, and Boston could see wind gusts up to 40 miles per hour, he said.
There doesn’t appear to be a threat of flooding, though Morrissey Boulevard could see some coastal flooding along with the winds, but “nothing too bad,” Simpson said.
The storm is expected to bring “significant amounts of snow” to Maine and New Hampshire on Wednesday night through the first half of Thursday, forecasters said.
Snowfall is expected to pick up in intensity Wednesday evening, potentially bringing 1 to 2 inches of snow per hour across southern areas of New Hampshire and across northern areas during the overnight hours, forecasters said.
Snow will overspread the area from southwest to northeast tomorrow afternoon and evening and it may fall heavy at times. Snow will then gradually switch to rain from south to north by Thursday morning south of the mountains.

Travel conditions are expected to “quickly deteriorate” across most of Maine and New Hampshire during the late afternoon and evening on Wednesday, and mixed precipitation will lead to slick travel on untreated snow later in the night.
