The low pressure system that made weather news today by bringing snow and ice across the deep South will track northeastward over the open waters of the Atlantic tonight. Clouds were on the increase through the afternoon and have overspread the area this evening as the ocean storm approaches far offshore later tonight.
Last night we mentioned the system was tracking further west and because of this snow was expected across Cape Cod and the Islands. It now appears the edge of the precipitation inches just up to our doorstep later tonight and then moves out early Wednesday morning. While forecasters are indicating a few inches of snow may fall across Cape Cod the drop off in the local area should be only an inch at most in the immediate Boston area and points south to a coating across the north shore with flurries possible elsewhere through the Merrimack Valley and the I-495 corridor. Cape Ann may see an inch or so out of this as well, but overall this is a very low impact event locally.
High pressure builds in on the heels of the departing low for Thursday then a weak cold front approaches Friday bringing an increase in clouds. There is just the slightest chance of a passing flurry, snow or rain shower in the afternoon, especially well inland.
The very cold air remains in place through Wednesday night as we continue to shiver in this latest blast of arctic air and try to figure out how we will pay those increasing heating costs. This has been a particularly cold stretch the last two months and as we approach the final days of January one has to wonder if we can catch a break in February.
Well, for the short term we do see a slight moderation in temperatures over the coming days with another threat for a light precipitation event this weekend, in particular Saturday and Saturday night. With a low pressure system tracking to our west we remain on the milder side of this system so it is a pretty good bet that we do get light rain, perhaps mixing with snow inland at night. Details later in the week.
