Flurries Possible for Some as Next Chance of Snow Aims for High Terrains

The combination of sunshine and milder temperatures means walkways, driveways and back roads will actually make some noteworthy melting progress on Thursday. They should clean up nicely with high temperatures in the 40s, though a steady westerly breeze will make it feel like the 30s.

Snow showers along the western and northwestern slopes of the Green and White Mountains are the result of an “upsloping” wind – wind pushing up against the western faces of the mountains and being forced upward to create localized stronger cloud growth.

It could cause localized snow bursts that accumulate 1-to-3-inches Thursday.

Although a few rambunctious flurries may carry into central and southern New England, not much impact is expected from these before the sky clears Thursday night with patchy black ice as melting snow refreezes.

Friday won’t be quite as “mild,” owing to increasing clouds that eventually deliver snow showers and a period of light snow from west to east, starting mid-morning to mid-afternoon, respectively. They may last into the evening, dropping a coating to less than an inch of snow for most.

Higher amounts of an inch or two is possible in higher terrain, mostly of central and southern New England.

Fresh moisture on the roads should lead to quite a bit of black ice overnight Friday. While ample sun is expected Saturday and a blend of sun and clouds Sunday with dry, Canadian air, that air will also be chilly with highs only near 30 Saturday and 40 Sunday.

The next storm is developing out of the nation’s midsection this weekend and will arrive with a swath of rain Monday as milder air surges northward. It may, perhaps, create some Monday morning pockets of valley freezing rain in the North Country, but mostly carry enough warmth to deliver plain rain. We may get an inch of it between Monday and Tuesday.

The problem with this rain is it will add a lot of weight to flat rooftops in central and western New England that received 20 inches and more of snow, so it’s really important that structures with flat rooftops clear the snow Thursday or Friday (presuming the weekend may be more difficult and will be frozen in place) to mitigate the threat of roof collapse.

The storm may end with a gasp of rain or snow Wednesday as colder air comes rushing in, setting the stage for what may be a very messy couple of weeks at the middle of December. As noted in our monthly forecast from Wednesday, a winter storm chance shows up next weekend in our exclusive First Alert 10-day.
