Broad southwest flow and a mild February air mass was in place across the region on the 3rd. As a very slow moving cold front approached New England precipitation overspread the area. Given how warm temperatures were, precipitation started as rain. As high pressure built into Quebec through midnight the northern end of the cold front accelerated southward through New England. Rain changed to snow from north to south. A weak wave of low pressure formed and rode northeast along the boundary. This enhanced precipitation during the morning of the 4th. Precipitation ended as snow for all areas during the evening of the 4th.
