Areas in the western part of Massachusetts could see up to 6 inches of snow, including Greenfield and Fitchburg. Areas in the middle part of the states, like Springfield and Worcester, could be up to 4 inches.

At most, about 2 inches of snow is expected in Boston, with even less accumulation likely in southeastern Massachusetts. Forecasters said in an online discussion that cities on the coast are more likely to see a mix of snow and rain.

Forecasters are warning that the conditions are likely to affect Wednesday’s evening run as well as Thursday’s morning run.

There is also a risk of snow and sleet in Massachusetts during the storm, with the western and central part of the state likely to experience the highest impact.

Meanwhile, New Hampshire and Maine could be hit again, with heavy amounts of snow expected on Wednesday. A winter storm watch is in effect for the vast majority of both states from Wednesday afternoon through Thursday evening.

The low pressure will bring a moderate to heavy snow streak late Wednesday afternoon and evening, the weather service said. Snow is likely to arrive during the evening drive in the southern regions.

A heavy accumulation of snow is likely, especially in the northern and interior regions, which could see up to a foot of snow in some areas. Mixed winter precipitation is expected in inland and coastal areas.
