BOSTON — Our winter storm is moving up the coastline today and will bring a wide variety of precipitation to the area. The storm has three distinct parts to it and each will be different.
This morning some Massachusetts areas may experience some snow that will then quickly change to rain, especially along the coastline south of Boston.
Across Cape Cod and the Islands look for rain, heavy at times to continue after the change and street flooding may be a problem in some areas.
During the afternoon the rain/snow line will push west through Boston and continue westward past route 495 after 3 p.m. It is during this time snow will stop accumulating for most areas east of Route 495 and south of the Massachusetts Turnpike.
While the heaviest of the precipitation will be ending, there will still be a period of sleet and freezing rain over interior sections. This will coat any new snow with a layer of ice.
The first half of the night will see some light rain, sleet or freezing rain. Late at night an area of backlash snow will move eastward, and across northern Worcester County and the Berkshires there could be a few inches of new snow. In the metro Boston areas, there may be a coating and up to an inch of snow. This could impact the Friday morning commute.
Winds will be strongest this afternoon along the coast where wind advisories are placed over Cape Cod and Cape Ann. During the overnight, winds will diminish. There will be some minor splash over of the waves along parts of the coast and some beach erosion as the tides comes in at around 10 p.m.
Any snow ends early Friday followed by lots of sunshine. Another very large storm moves by to the east of New England Saturday and brings clouds and the chance of light snow with it, especially along the coast. This doesn’t look to be anything more than a dusting at this stage.
Cold and dry weather returns for Sunday with a warm-up next week, though more rain and snow will threaten the area.
Friday: Cloudy with a drizzle this morning and a period of showers and heavier downpours later this afternoon and evening. Thunder is possible. Highs just over 50 south of Boston and in the 40s north of the city.
Friday night: Rain ends early, then skies clear. Lows will be in the upper 20s to near 32 degrees.
Saturday: Sunny with highs in the mid-40s.
Sunday: Mostly sunny with some clouds late in the day with a rain or snow shower at night. Highs between 40-44 degrees.
Sunday Night: A few snow showers and turning colder. Lows between 20-25 degrees.
Monday: Mostly sunny, but cold with highs between 28-31 degrees.
