The light snow early Monday was a disturbance caught in the extremely large circulation of air that lingers across the Western Atlantic from our powerhouse early weekend storm.

That storm is nearly a thousand miles away, now, but has become so large it’s still churning air counter-clockwise around its center all the way into New England and the Canadian Maritimes.

Influence of the storm will weaken on New England over the coming days, first delivering fair weather before another storm comes calling Wednesday into Thursday.

Cool air holds daily high temperatures around 40 both Monday and Tuesday, but today is the windier of the two days, with north-northeast gusts to 40 mph creating a wind chill in the 30s during even the warmest time of the day.

Of course, with the cool air unrelenting this week, that means when our next storm approaches for midweek, snow will be in the cards for many of us. It looks like we’ll escape with a dry Wednesday morning commute, but by midday light rain and snow will begin and ramp up during the afternoon and fall heavily during the evening and overnight, departing Thursday morning.

The tide levels will be much lower than our previous nor’easter, so coastal flooding will not be nearly as much of a concern, save for some possible minor flooding in vulnerable locales.

Similarly, wind gusts will be a fraction of the power as our last storm, gusting to 50 mph on Cape Cod and 40 to 50 mph for the rest of our coast.

Because the storm strengthens in the Gulf of Maine, the most snow is expected in the Pine Tree State with over a foot – and lesser amounts of 3 to 6 inches in Boston, less in southeast New England and 6 inches or more possible outside of Route 495.

After some lingering snow showers Friday, particularly in the mountains, another storm will come calling with snow and rain Sunday night into Monday in the exclusive Early Warning Weather 10-day.
