How Much Snow Will Massachusetts Get? – NBC Boston

While New England enjoys a brief mid-week thaw, this time of year has a good chance that more wintry weather is just around the corner, and we won’t find any exceptions this week.

For now, New England is on the warm side of a developing storm system – a beam of intense energy moving across the country’s midsection and building on a combination of heat and humidity from the Gulf of Mexico and the clash with intense Canadian cold pushing into the northern United States, resulting in an acute cold front pushing southeastward into the Ohio Valley.

This cold front will be key to forecast details in the days ahead, marking a sharp change from raindrops and 40s to snowflakes and 20s, which are expected to move very slowly south across New -England from Thursday to Friday. By then, milder temperatures will bring enough melt that the snow still on roads, driveways and driveways will turn slushy and sloppy, although the refreeze we’ve seen in recent nights is unlikely for most of between us Wednesday evening with temperatures remaining above freezing after a daytime high around 40 for all but extreme northern New England.

The arrival of warmer air will see plenty of cloud Wednesday through Wednesday evening, although raindrops are likely to remain fairly limited, with a few splashes or light showers in southeastern Nova Scotia. -England Wednesday noon and afternoon.

Otherwise, Thursday brings the advance of more regular rainfall as the storm system to our west closes in, first spreading mixed snow and rain showers across northern and western New England, then s extending as rain for the rest of us from morning to Thursday noon, arriving last on Cape Cod in the afternoon.

As the well-defined cold front coming into New England approaches, it will slow down considerably but will also clearly mark the onset of a northerly wind and colder air, turning all of northern New England to snow. Thursday evening and introducing sleet. and freezing rain in central New England before turning to snow overnight Thursday night.

An intense cold front from Thursday to Friday will turn the rain into freezing rain, ice pellets and snow.

There is a lot of moisture in the Gulf of Mexico with this system, so even after the shift to snow, enough precipitation falls for a snowfall of 12 to 18 inches in the northern mountains with widespread snowfall 8 to 12 inches for most of northern New England.

The further south you are, the longer it takes for the slow-moving cold front to arrive Thursday night and Friday, and the less precipitation there is that falls as snow before stopping Friday night. Still, enough snow is expected to fall for a two-inch coating even in some communities in far southern New England, with amounts expected to gradually increase with the extent of the north.

The timing of the cold front is crucial, as it will mean temperatures will drop below freezing from north to south across southern New England on Friday, causing water to freeze on some roads.

As the center of the storm continues eastward and the humidity recedes Friday evening, the disorder ends and cold, dry air settles in New England over the two weekend days with a stronger wind Saturday than Sunday.

Next week there are no days that trigger storms, but the jet stream pattern really favors potential storm development and our proprietary NBC forecast system indicates a higher chance of precipitation on Tuesday and Friday, we so let’s keep a close eye on our 10-day forecast.
