An area of low pressure moved from the Ohio Valley towards the mid-Atlantic states on Wednesday, March 12th.  Precipitation spread across the region from west to east during the early morning hours. Although the precipitation fell across the Adirondacks as snow, areas further south initially saw mainly rain.  As the morning hours went on and low pressure continue to strengthen, cold air at low levels began to move into the region from north to south. This allowed the rain to change to sleet and freezing rain across the Mohawk Valley and Saratoga Region. Eventually, precipitation changed to freezing rain across the Capital Region and Schoharie Valley by early afternoon as well, with snow becoming more common in the Saratoga Region and upper Mohawk Valley.
The low pressure area moved towards the New York City area by early evening, and strong, northerly winds continued to transport colder air into the region.  This allowed the wintry mix to change to snow from north to south, with wintry precipitation even making into the mid Hudson Valley and Catskills by late evening as well.  The low pressure continued to move eastward towards the eastern New England coast for the overnight hours.
Steady precipitation tapered off during the overnight hours, although a few localized bands of snowfall continued into the morning hours, including over parts of the Capital Region and Taconics.  By the time precipitation had ended, snowfall amounts ranged from just a coating to a few inches across southern areas to as much as one to two feet over the Adirondacks.  Ice accretion was up to a quarter of an inch, with the highest totals over Schoharie, Saratoga and Washington Counties. In addition, gusty northwest winds in the wake of the storm allowed for blowing of snow, especially across the Adirondacks.  These winds, along with unseasonably cold temperatures, allowed for a very cold day, despite it being mid March.
