Low pressure moved into the Ohio Valley on the 31st, where it began to encounter resistance from high pressure anchored over James Bay. As the upper trough continued east, secondary low pressure began to develop along the warm front near the Outer Banks. This new low pressure center deepened and quickly occluded south of Long Island by midday on the 1st. It meandered south of Long Island into the morning of the 2nd before finally moving northeastward into the Gulf of Maine during the latter half of the day. During the occlusion phase a strong, pivoting mesoscale band of heavy snow impacted parts of the Mid Atlantic, while the northeastern extension of the band remained rather progressive lifting through New England. The heavy snow ended early on the 2nd but snow and significant amounts of sleet continued through the day for much of western Maine. Precipitation tapered off late on the 2nd. Key Impacts: transportation delays, traffic accidents, heavy snow, heavy sleet.
