Of all the storm impacts that Massachusetts could see with the nor’easter hitting the region Friday and Saturday, forecasters say exactly how much snow will arrive with the coastal storm remains uncertain.

“Our best and worst case scenarios reflect a wide range in possible outcomes,” the National Weather Service said on Facebook Thursday morning. “These range from little if any snow at all to a scenario with significant snow accumulations and power outages.”

The accumulation predictions from the service range from no snow to as much as 7 inches in Boston.

Boston could see rain switching to snow after 8 p.m. on Friday and continuing overnight into Saturday morning, according to the service’s seven-day forecast for the city.


Meteorologist David Epstein has a detailed forecast for Friday and Saturday, and the National Weather Service has released a series of maps focused on the potential impacts of flooding and rain. Below are seven maps from local forecasters attempting to predict how much snow Massachusetts could see.
