The episode as NWS ALY wrote it up.
A low pressure system tracked from the lower Ohio Valley on Tuesday January 6th, into the eastern Great Lakes during Wednesday January 7th, and into northern New England by Thursday morning January 8th. A second low pressure system developed near Long Island during Wednesday, and tracked northeast along the northern New England coast by Thursday morning.
This combination of low pressure systems spread a swath of moderate to heavy precipitation across eastern New York and western New England, beginning late Tuesday evening, and ending early Thursday morning.
The precipitation fell as a mix of snow, sleet and freezing rain across the region, before gradually changing to plain rain from south to north during Wednesday as milder air approached from the south. As colder air wrapped back into the region, the precipitation changed to snow before ending later Wednesday night and early Thursday morning.
Snow and sleet amounts ranged from 1 to 4 inches for areas south of the Mohawk River Valley, including within the Capital District, Schoharie Valley, the mid Hudson Valley and eastern Catskills, and the central and southern Taconics, with generally 4 to 8 inches further north, including within the central and eastern Mohawk Valley, and the Lake George and Saratoga region. Locally higher amounts, with 8 to 10 inches, fell across portions of the southern Adirondacks.
In addition, ice accretion from freezing rain generally ranged from one tenth, to three tenths of an inch, with the greatest amounts occurring within the immediate Capital Region north into the eastern Mohawk Valley.
This wintry mix led to widespread hazardous travel conditions during Wednesday morning. In addition, numerous closures, or delayed openings of schools and businesses occurred Wednesday morning.
