A low pressure system developed over the southeast states during Thursday afternoon on March 15th, and then tracked northeast while intensifying, reaching the Delmarva coast by Friday evening on March 16th, and off the New England coast by Saturday morning on March 17th.
This storm brought widespread snowfall amounts of 10 to 20 inches across eastern New York and western New England, with some amounts of near two feet across the eastern Catskill region, as well as within a band extending across southern Columbia, and northern Dutchess counties of New York.  The snow began across the lower mid Hudson Valley during the mid morning hours of Friday, March 16th, and spread into the Capital Region during midday.  The snow did not reach portions of the western Mohawk Valley and southern Adirondacks until the late afternoon hours, as dry air remained in place longer, allowing the precipitation to remain aloft for several hours before reaching the ground.  This also allowed snowfall amounts to be less across this region, with generally 6 to 9 inches occurring.
Further to the southeast, some sleet mixed in with the snow, beginning during the early evening hours of Friday, and persisting into Friday night, keeping snowfall amounts a bit less across the lower mid Hudson Valley, where an average of 8 to 12 inches occurred.
This storm had significant adverse impacts to travel and commerce across the region from Friday afternoon into early Saturday morning. Travel was treacherous for the Friday evening commute, with numerous accidents reported.
