Thanksgiving in Massachusetts is expected to be wet as another storm is expected to drench the state.

After a dry Wednesday, a system is expected to move into southern New England, but the National Weather Service said it is not clear when this will happen on Thursday.

However, rainfall is expected to start at different times in major cities of the state. First in Worcester, when rain is expected after 3 a.m. and will end sometime before noon, forecasters said. Precipitation totals in Worcester could accumulate between a tenth and a quarter of an inch.

Similarly, in Boston, rain is expected to start after 7 a.m. and end before 2 a.m., forecasters said. During this period, Boston could see between one-tenth and three-quarters of an inch.

Springfield should also see an extended period of rain Thursday, likely starting after 5 a.m., forecasters said. Rain should stop before 11 p.m. and total between half an inch and three-quarters of an inch.

According to AccuWeather, Boston, Worcester and Springfield should see nine hours of rain on Thursday.

“In virtually all cases, precipitation is expected to continue through mid-day through late afternoon,” National Weather Service meteorologists wrote.

Light snow is expected to fall in areas at an altitude of 300 metres, forecasters said. Between 1 and 7 inches of snow is largely expected, although forecasters expect “higher amounts” to be possible.

“At this time there are no plans for winter weather news on Thursday,” forecasters added.

The snow and sleet risk for Massachusetts on Thursday is limited to the Berkshires, according to a hazardous weather outlook map.

Two winter storm watches will go into effect in New England starting Wednesday morning and lasting until Thursday evening. One watch covers Bennington and Windham counties in Vermont, and the other covers south-central and southwestern Maine and central, northern and southern New Hampshire.

Heavy snow is expected to fall, with about 6 to 18 inches expected to accumulate, the watches said.

“Roads, especially bridges and overpasses, are likely to become slippery and dangerous,” said the storm watcher at the National Weather Service office in Albany. “Take slippery roads into account. The hazardous conditions could impact travel around Thanksgiving.”

While some scattered rain showers will be seen Friday, most of the week’s precipitation should end Thursday evening, forecasters said. Snow should continue to fall in higher elevations until Friday morning.
