Under the influence of high pressure, Tuesday morning will begin in the single digits or teens across the Mass Pike leading into the city. Some of that frigid air is originating from Northern Canada, making it feel once again like the depths of winter are upon us.
Tuesday won’t be seeing strong winds by any means, but a slight breeze will be enough to plunge wind chills to near zero degrees across most of Southern New England. Some folks up north could once again banger sub-zero temperatures.
Afternoon highs across Boston will crawl to around the freezing mark, while folks north and west remain subfreezing. You’ll have to head to Rhode Island or the Cape to find temperatures Tuesday afternoon in the mid to upper 30s.
On the plus side, Tuesday will begin with mostly sunny skies as high pressure drags across the region and into the Gulf of Maine. However, increasing clouds will follow suit around the commute home to around the 7 p.m. hour.
Behind the exiting high-pressure system will be a quick-moving clipper system that will bring scattered light snow showers to the region late Tuesday night into the overnight. Available moisture will be scarce, so any snowfall should only lead to a coating at best, with Boston holding a low chance of seeing any snowflakes.
If any snow does fall across Boston, it will be light and brief, falling mostly overnight.
Next weathermaker: Wednesday morning snow, rain
Trailing right behind Tuesday night’s clipper will be a more organized storm that is likely to take more of an inside track across New England and bring accumulating snow. This slightly more intense storm is expected to arrive mid- to late morning on Wednesday and last through Wednesday evening, leaving about 1 to 3 inches of snow in parts of Worcester County to the Berkshires.
The track of this low-pressure system will draw a southerly flow into the region and keep Boston in the warm sector, resulting in plain cold rain after a potential wintry mix Wednesday morning. We’ll have a better idea of where the rain-snow line will develop at some point on Tuesday, but regardless, it should stay west of the city and set up closer to Worcester than Boston.
This won’t be a big storm, but there will be accumulating snow across portions of Western and Northern New England.
Areas across the Berkshires, northern Worcester County, and into Northern New England may see 1 to 3 inches of snow, with a few spots up north nearing 6 inches, especially in the higher elevations.
Greater Boston: Mostly sunny with a frigid start and cold afternoon. Highs in the low 30s across the city and North and South Shore. Clouds increase around sunset. Scattered light snow showers possible overnight.
