This week will again be a bit of a weather roller coaster as a few passing weather systems impact New England. After Sunday’s four-inch snow accumulation was washed away by over half an inch of rain on Monday, the remainder of the week will bring a few more weather extremes. After a relatively normal day today, gusty winds from the southwest will bring warm air to the area tomorrow. However, a cold front tomorrow night will then immediately knock temperatures into the mid-teens (°F).

Perhaps Punxsutawney Phil was right on Groundhog Day when he predicted an early end to winter this year. Since Feb. 2, there has been no accumulating snowfall in Boston, and about 10 inches of existing snow cover has melted away. Additionally, this week will feature some of the highest temperatures of the year so far. Yesterday’s high temperature of 56°F was our highest recorded temperature since Jan. 1, and temperatures could reach the 50s once again by the end of the week.

As our area recovers from its latest bout of wintry weather, yet another snowstorm is set to impact the region this weekend. Once again, a coastal low pressure system currently located over the southeastern states will make its way northward, bringing with it wintry precipitation for Saturday and Sunday night.

Another nor’easter is headed toward the Boston area, and it will bring more snowfall to the region tonight and tomorrow morning. However, as of Tuesday there was still a considerable amount of uncertainty as to the severity of the storm’s impact. The storm, which was centered over the Gulf of Mexico yesterday, will be tracking northeastward along the Atlantic coast of the United States throughout the day today. The exact track that the storm takes will dictate the amount of snow that we receive, since sharp precipitation gradients mean that a slight deviation in track direction can translate into a large difference in snowfall totals.

A proverbial grab bag of weather will be on display this weekend, with clouds, sunshine, rain, and possibly even snow all on tap. First, clearing skies and calm winds will result in some of the coldest air of the autumn this morning, with temperatures plunging into the mid-teens. However, as a high pressure center drifts offshore, southerly flow will advect warm air to our area, and temperatures will increase steadily throughout the day and overnight, bringing Saturday’s high to the mid-40s.

The season’s first forecasted chance of snow is in the cards for our area this weekend, but chances are low that we will actually see much, if any, of the white stuff. From Saturday night into Sunday morning, precipitation associated with a cut off low pressure system located over northeastern Maine could push south into our area. The result could be a few overnight or early-morning sprinkles or flurries. However, the chance of precipitation will be slight, and a significant snowfall will be highly unlikely.

A pair of cold fronts will cool things down in New England this weekend, bringing our area some of its coldest temperatures of the fall to date.

A vast high pressure system will take hold of the northeast United States for the first half of this week, resulting in calm, sunny conditions for our area. In fact, there will likely not be a cloud in the sky today, as the high pressure system slowly approaches from our west. However, the same system is currently causing cold air to be advected from our north, meaning temperatures will likely not break 50°F for the next two days.

Going out for Halloween festivities this weekend? Bring a jacket, as temperatures will dip into the low 40s (°F) each night.

The pleasant fall weather that has been prevalent so far in New England this year will continue this week, with sunshine, light winds, and temperatures around 60°F. With last week’s nor’easter long gone out to sea, and no new storm systems expected to pass through the area until the end of the week, seasonable autumn weather will continue to dominate for the foreseeable near future.
