How much snow will we have on Saturday? – NBC Boston


New England is enjoying a break between the weather systems on Thursday and Friday, with both afternoons recording high temperatures near 50 degrees.

On Thursday, that means slush – much of it clinging to tree branches and power lines – will initially fall in large, sloppy clumps as temperatures warm, then lead to puddles and spray. roads later in the afternoon.

With temperatures expected to dip below freezing for most communities on Thursday night, patchy black ice will develop by dawn Friday and could be exacerbated by patchy fog developing in the air below the freezing point. freezing for part of southern New England, so slippery patches on Friday morning are likely to be an early feature.

Next, attention turns to a rapidly developing storm that will move from the Gulf Coast to New England Friday evening through Saturday, then track northeast across Atlantic Canada from here Saturday night.

Will a bomb cyclone hit Massachusetts?

This storm will be close to reaching criteria for a “bomb” – technically defined as a deepening, or strengthening, of the storm’s center by about 24 mb on the barometer in 24 hours – implying a storm ripe for the production of heavy precipitation and gusts. wind, with the recipients of each determined by the exact path of the storm.

What you need to know about this winter weather phenomenon.

Parts of New England could see a foot or more of snow

From our Thursday morning view, our first warning team sees Saturday rising with rain for many locations, but the rapidly strengthening center of the storm approaching from the south will draw air toward its center, blowing our north wind and changing the rain fairly quickly. snowing in northern New England Saturday morning and setting up northern and western New England all the way south through the Berkshires for 6 to 12 inches of snow, with a foot to a foot and possible half from northern New York to northern Vermont to northern Maine!

This snow will be a late-season boon for skiing and snowmobiling in the north, but our question to answer is how much snow will creep into the south and the New England coast?

Right now, it looks like nearly an inch of rain is falling across southern and eastern New England on Saturday, but as the center of the storm passes over the Gulf of Maine, the Colder air over northern New England will push south, turning rain to snow, and the exact timing of that will be key to how much snow falls.

Heavy snowfall is expected at least in northern and western New England on Saturday, but southern and eastern regions are also watching closely.

How much snow will Boston get on Saturday?

At this point, our proprietary in-house NBC forecasting system has been consistent over the past few days of a two-inch coating from Portland to Boston, Worcester and Hartford, and while that’s the most likely scenario, it wouldn’t take a big move for 2 to 4 inch amounts expected in the Monadnock area and northwest of the Worcester Hills to move a little further southeast.

What is the risk of power outages?

Wind was initially seen as a concern for this storm, but the recent southeasterly trend in track, while introducing the potential for a snow swing, also dampens the forecast wind speed for now to gusty generally less than 50 mph with the exception of Cape Cod – again the path of storms will be important in this regard.

The storm left on Sunday, however, with a beautiful, windy day of cold winter weather with wind chill readings in the 20s before a marked rebound in temperature to spring-like air for most of next week.

And don’t forget – we’re moving the clocks forward one hour for daylight saving time on Saturday night!
