Low pressure formed on the 24th along a warm front draped over the Southeast. The low deepened gradually as it lifted northeast through the Tennessee and then Ohio River Valleys during the evening of the 24th. An area of high pressure branched to the north of the advancing system, with cold air damming spilling down the eastern slopes of the Appalachians. The primary low pressure began to fill near Lake Erie with secondary low pressure developing off the Mid Atlantic coast. This low became the dominant one near Nantucket by midday on the 25th. A band of snow lifted into northern New England and then slid east through the day on the 25th, as the center of low pressure raced east northeast to the south of Nova Scotia.
