Weekend ‘snowstorm’ will likely be a dud

Before the final flakes had even fallen Tuesday, there was already talk of another possible snowstorm for the weekend.

After the relatively mild winter, the thought of back-to-back snowstorms this time of year wasn’t something most of us were looking forward to. The greening grass and crocuses of February are already encrusted under a mantle of white in nearly all of New England. More snow would only delay the inevitable arrival of spring that much longer.

If you don’t want another snowstorm, there is good news in the forecast. Even if we get some snow Saturday into Sunday, this isn’t going to turn into a big storm. Each successive model run over the past two days has pushed the upcoming storm further south and east. This means the chances of significant snow this weekend are now less than roughly 20 percent.


What I foresee happening is a weak Alberta Clipper, low pressure area will dive southeast and then move off the coastline of the Mid-Atlantic. From this point it will travel east northeast, strengthen, and move out to sea. The intensification of the storm will be too late for a big impact.

Cape Cod and the Islands may be on the western fringe of the storm and see some light accumulating snow on the order of a coating to a few inches. In other words, no big deal.

I do need to insert the buyer-beware clause at this point. This is weather folks and the track could still change, so while I am pretty sure this won’t turn into a snowstorm for us, it’s still smart to check forecasts into the weekend as the atmosphere can always bring a surprise.

Once skies clear, it will turn more seasonable and there will be some melting. Temperatures Monday and Tuesday should break the 40-degree mark. The sun this time of year is about the same as the final week of September, becoming a bit more intense and lasting longer each day.


While the storm likely won’t happen, there is more cold air on the horizon. An Arctic front crosses New England in the middle of next week. Behind, another mass of air from northern Canada drops temperatures some 10 to 20 degrees below average. I expect single digits to show up on the weather maps in the latter half of next week.

There are early signs of a moderating trend after that. Of course by then it’s April and having temperatures in the single numbers at that point in spring is highly unlikely.

Yes, April snow is coming
