What the National Weather Service wrote

The wider storm
A frontal wave developed in the lower Ohio River Valley on the 18th and lifted northeastward towards Lake Erie. Cold air damming remained entrenched and secondary low pressure began developing farther east along the warm front, south of New England. This low slowly strengthened as it moved east northeastward just over the tip of Cape Cod. While snow overspread the entire area, the mid level warm front was able to advance into southern New Hampshire and changed precipitation over to sleet and freezing rain. The heaviest snowfall ran roughly west to east through the Lakes Region.
