Forecast discussion: A low pressure system staying well south of Southern New England is still depositing light snow showers across the state as of 4 p.m. Meanwhile, latest radar imagery shows heavier bands of snow still pushing through Boston, as well as Bristol and Plymouth Counties. Barrington received 2 inches, as well as Pawtucket. The southern parts of the state received 3-5 inches. The snow will come to an end over the next 3 hours, as the moisture moves offshore. The Cape and Islands may keep some snow showers lingering, due to northeast winds coming off the ocean.
As we head into Wednesday, a trough over the Tri-State area will create a low pressure system, which will move over western Massachusetts by the afternoon. This low could create some snow showers after the evening commute. There is a chance snow showers will intensify to light snow by early Thursday morning. The light snow will continue right into early Thursday evening, before the low moves offshore. Because the moisture content is light, it is difficult to say if we will see any additional snowfall. A coating to an inch is possible, if it remains just scattered snow showers.
As we head into Friday, a strong high pressure system will bring drier weather to the east coast. But with the bright sunshine comes another blast of Arctic air over New England. High temperatures will fall from the lower 20’s on Thursday to only the middle teens on Friday. Overnight lows Thursday and Friday night will struggle to stay above 0. The dry weather will hold into the daytime hours on Saturday, but we must watch for another potential storm for Sunday.
However, for once, warmer air will arrive with this system. So, we may start off as some snow, but as the warmer air arrives, that precipitation may change over to sleet, freezing rain, and sleet. There is the slight chance it could just become plain rain. So, accumulation totals at this time might be light. However, as the cold front pushes through later Sunday night, the precipitation changes back to snow. The snow will remain light into Monday afternoon. We end the forecast period with high pressure giving us back mostly sunny skies for next Tuesday, but high temperatures will remain in the middle 20’s.
