Wider weather episode

Low pressure moved through the Ohio River Valley late on the 1st and tracked into New York early on the 2nd. A secondary low pressure began to develop early on the 2nd in the vicinity of Chesapeake Bay. By sunrise the secondary low pressure had become dominant and moved across Buzzards Bay and through the Gulf of Maine. The initial wave of precipitation moved in with strong warm air advection aloft late on the evening of the 1st. Early in the morning on the 2nd above freezing air and drying out of the column allowed some of that precipitation to change over to sleet, freezing rain, and rain. As the storm deepened in the Gulf of Maine, mid levels cooled and precipitation flipped back to snow for several hours before ending around midday.
