The National Weather Service issued a winter storm warning for eastern Massachusetts, including the Boston area, and Rhode Island through 7 p.m. ET Sunday. Up to 10 inches of snow accumulation was possible for some areas on Sunday, the weather service said.
The culprit is a large dip in the jet stream that brought colder-than-average temperatures to the eastern U.S., Weather.com reported, resulting in freeze warnings for parts of northern Florida. That was combined with a low-pressure system heading north that was expected to be off New England Sunday morning.
