Snow fell across areas of Massachusetts last night but as expected it was primarily over southeast Massachusetts, including Cape Cod and the islands. A general 2 to 4 inches of snow fell over this area, with the accumulating snow reaching into Plymouth County where Hanson reported an inch and Plymouth 2 inches. According to reports submitted to the National Weather Service the highest total reported was 5 inches in South Sagamore. New Bedford came in with 3 inches and Sandwich with 4 inches. For the immediate metro area and the suburbs to the north and west it remained dry overnight. We thought a few flurries or snow showers may creep into the Boston area but it was not to be.
With a weak high pressure system building into the Northeast over the next two days we are looking at pleasant mid February days for Thursday and Friday. The early clouds of this morning have given way to a bright sunny day. Temperatures once again climb into the low 40s and winds should mainly remain under 15 mph from the northwest. Some clouds will be around tonight as lows fall into the mid and upper 20s, followed by a repeat performance on Friday. Actually, temperatures should be even milder as highs into the mid and upper 40s are likely. Winds may get feisty in the afternoon, possibly gusting to over 20 mph. We have had a tremendous amount of snow shrinkage this week, due to the mild temperatures, and the next two days will only continue to enhance the melting.
Now for some downside on the upcoming weather. A low pressure system will track north of us into Friday night. This will swing a cold front through here early Saturday with a low developing along the front as it moves offshore. The offshore low is forecast to strengthen as it moves northeastward into the Canadian Maritimes. As it does so we may break out with a period of light snow or a snow rain mix during Saturday on the backside of the low. An inch or two of accumulation is a safe bet right now through the interior. Conditions should improve early Saturday night as the low pulls away toward Atlantic Canada. Sunday and Monday will see a return to sunshine but with a cold northwest wind that may gust upwards of 30 mph at times, especially Sunday.
Colder air on the backside of this system will begin to overspread the region and this will be reflected in much cooler forecast temperatures Sunday and Monday. Highs on Saturday will not be as mild, with highs in the mid 30s inland to upper 30s on the coast. For Sunday the mercury only reaches the mid and upper 20s and maybe a couple degrees higher Monday. Overnight lows drop into the teens Saturday night and Sunday night. Monday night lows in the upper teens inland to low 20s on the coast.
Tuesday should present another opportunity for precipitation as low pressure approaches from the Great Lakes. We could be mild enough for mostly rain on the coastal plain to a wintry mix inland.
