The day starts with EVERY rain on site. The cooling temperature shifts on Saturday afternoon and causes snow in much of the area. In fact, outside of North and Central MA 495, this transition starts in the late morning from the middle. Snowfall of 6-10 6 is possible here. In the Boston area, there is likely to be a distance between 3 ″ and 1-3 ″ south of the city, where the change will only occur in the middle or late afternoon. We insist on all the rain for the south coast, the Cape and the islands.
