After averaging nearly 10 degrees colder than normal through the first week of the month, the second weekend of March featured a reprieve with high temperatures over 50 in most locations in southeastern New England Saturday. And though Sunday will quite a bit cooler (upper 30s to lower 40s) it was still quite tolerable.
Now, it’s onto the coming week, which will feature a variety of weather – something March is quite known for. It starts out with some snow showers and lots of clouds Monday as a disturbance passes through the region along a frontal boundary. A low pressure area approaching the region from the northwest Tuesday will drag this front northward and allow some mild air to flow into southeastern New England, before the low’s trailing cold front slides through the region Tuesday night as low pressure moves off the New England Coast. This battle zone between much colder air to the north across eastern Canada and northern New England and mild air just to the south will provide an avenue for a more important storm to travel, impacting southeastern New England Wednesday into Thursday. The exact track of the low pressure area which will be coming across the Midwest and into the Northeast will be crucial in determining precipitation type. At a few days away, I am not confident just how it is going to work out yet, but my leaning is toward a track a little further south than most computer guidance suggests, and a colder scenario, but a close enough track for some rain over at least southeastern MA and RI and up to around Boston, with mostly snow to the northwest. This will be tweaked and fine tuned, of course, as the event draws closer.
Once the storm moves away, a chunk of Arctic air will be pulled southward out of eastern Canada and make it feel like mid winter on Thursday, along with some very strong wind as the low intensifies rapidly as it heads for the Canadian Maritimes. By Friday, high pressure will move in, eliminating the wind, increasing the sun, and moderating the temperature.
By the time we get to next weekend, another disturbance will approach and cross the region, but best info this far out suggest it will not be a major system.
