Lexington could see 2 to 4 inches of snow over the weekend, according to the National Weather Service.
NWS has issued a Hazardous Weather Outlook for the area with snow showers expected Friday night and steady snow on Saturday. The steady snow should taper off by 5 p.m. Saturday, with patchy freezing fog and a chance of snow showers as temperatures dip into the teens.
The snowy conditions will be joined by fog and winds that may exceed 20 mph.
NWS said there is a “moderate to high probability that winter weather advisorires will be needed for a portion of southern New England.”
The heaviest snowfall is expected to hit Rhode Island and southeastern Massachusetts, but NWS warned that a shift in the storm track could result in changes in the type of precipitation and amount.
