It will not take long for the snow to become steady and it will accumulate rapidly.  Most of the snow South of the Pike and Inside 495 falls between 7 am - 5 pm.  Here is the 4 PM simulated radar

It is raining from Boston-Providence-Hartford South and East.  Ice will be an issue near the Pike and 495 so communities like Marlboro, Northbridge, Lowell etc will likely see 6-10 inches of heavy wet snow and then a layer of sleet/ice on top.  

Winds will also increase this afternoon. With heavy wet snow and some ice accumulation there is a moderate chance for power outages.  The WPC expects 1.5-2.0" of precipitation to fall over the next 48 hours

WPC 2 day precipitation outlook

Overnight tonight a final band of snow will work SW to NE across Southern New England.  The low will be in the Gulf of Maine and with a sub 980 pressure
