While some forecasts call for up to a foot of snow west and north of Boston this weekend and as much as four to eight inches in the Braintree area, the National Weather Service is warning residents to be aware of the approaching coastal storm but also advising that its track and accumulation remain uncertain.
"There is high probability for a strong coastal storm to impact Southern New Englan late Saturday into Sunday," the service wrote in a Hazardous Weather Outlook. "A lot of uncertainty remains given that the storm is still nearly 3 days in the future."
As of Thursday morning, the National Weather Service was predicting a chance of snow starting after 2 p.m. Saturday in Braintree. A rain/snow mix is likely Saturday night, with it turning to all snow early Sunday morning. Snow and rain could continue through Sunday night.
The agency is currently only predicting an inch or so of snow for Braintree during the course of the storm, though WHDH meteorologist Pete Bouchard says the South Shore could see four to eight inches, with the higher amounts closer to the water.
The National Weather Service further warns residents:
"THE STORM WILL BRING THE POTENTIAL FOR HEAVY WET SNOW TO THE REGION. AT THIS TIME...THE BEST CHANCE FOR THIS WILL BE NORTH OF THE MASSACHUSETTS TURNPIKE AND AWAY FROM THE COAST.
"HOWEVER...THE THREAT FOR A PERIOD OF HEAVY SNOW IS POSSIBLE ACROSS MUCH OF THE REGION. THERE WILL BE THE POTENTIAL FOR SOME DOWNED TREE LIMBS AND POWER OUTAGES WHERE HEAVY WET SNOW OCCURS.
"STRONG WINDS ALONG THE COAST MAY ALSO REQUIRE THE NEED FOR SOME WIND HEADLINES. FINALLY...COASTAL FLOODING AND BEACH EROSION ARE POSSIBLE ALONG THE EASTERN MA COASTLINE WITH THE HIGHEST RISK DURING THE SUNDAY MORNING HIGH TIDE."
