Metro Boston, North Shore and Metro West: Light snow arrived around daybreak or soon thereafter in the local area on Thursday. Fortunately the snow remained light through the morning commute. By midday areas right along the immediate coast had briefly changed to a period of rain. Elsewhere, snow was becoming heavier as a burst of very heavy snow fell through the midday and early afternoon hours. A report out of Concord, MA had almost 4 inches of snow falling in a one hour span as reported on a local weather report. The rain on the coastline quickly flipped back to snow for several hours with a few inches accumulating through the afternoon.
Again, right along the immediate coast some locations began to mix with rain and some sleet by late afternoon then to all rain by evening which has kept the snowfall totals in check there. Meanwhile, snow was piling up not very far away from the coast and the further inland you went the higher the snow totals.
Here are some “unofficial” snow totals as of late afternoon courtesy of the National Weather Service: Sudbury 11 inches, Lowell 10 inches, Natick 9”, Wakefield and west Peabody about 7.5”, Topsfield 6.5”, Danvers 6”, Woburn near 6”, Saugus 3.5” and Gloucester 3”. Snow accumulations of 8 to 12 inches were reported across western Massachusetts.
The storm continues into tonight, although the heaviest of the snow has fallen. Additional light accumulations are possible overnight away from the coast, with generally rain along the coast. A Winter Storm Warning remains in effect until 7 am Friday across interior northeast Massachusetts and metro west. Some mixing is taking place a bit further inland this evening but is expected to turn back to all snow where any mixing has occurred across interior sections. Far inland sections are not expected to see any mixed precipitation. As the storm center moves just south of Boston tonight and into the Gulf of Maine Friday morning the rain and or mixed precipitation changes back to snow along the coast. Some wrap around precipitation continues into early Friday morning as the storm winds down. Temperatures will remain steady overnight in the low 30s.
It has become increasingly windy through the afternoon and will continue to do so tonight. Because of the heavy wet snow on tree limbs the strong gusty winds may cause tree limbs to snap taking down power lines and in turn causing scattered power outages. There is a Wind Advisory in effect until midnight across eastern Essex County and Suffolk County for winds that can gust to near 50 mph. This advisory is also in effect for the coast south of Boston along eastern Norfolk and eastern Plymouth Counties.
Coastal flooding is not a big concern for tonight's high tide cycle although minor flooding and splash over, along with some beach erosion is possible along the North Shore, especially Cape Ann northward to Salisbury Beach.
We do get into a brief drying out period Friday afternoon and Friday night but another disturbance is going to quickly follow on the heels of this departing storm and poses a threat for a period of light snow Saturday and possibly into Saturday evening. More on that during Friday’s update.
