Pre Storm Observations
Good Morning. Light snow is arriving in Southern New England as of 530 am. Heavy snow, rain, sleet, ice, and wind will impact the region through early Friday morning. Winter Storm Warnings have been extended into Essex and Suffolk Counties.
Wind Advisories exist for the east coast of MA from the Cape up to Gloucester.
High pressure has scooted east into the Atlantic but as you can see there is impressive cold that remains. Our storm is deepening already off the Carolina coast. Here is the surface chart
Here is an awesome satellite shot of the East Coast. This is the Water Vapor satellite
Here is the radar this morning. DC has 6" of snow already and it is still snowing there. They will eventually change over to rain
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.
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
So my final snow forecast is
