A complex multi-part long duration (24 to 36 hour) storm blanketed east central New York and western New England with 3 up to 15 inches of snow and sleet on Wednesday, February 29th and Thursday, March 1st.
A large low pressure system approached from the upper mid west and Great Lakes region Wednesday. In association with the system's warm front, snow initially overspread the area Wednesday with bands of heavy snow occurring with snowfall rates of 1 to 2 inches an hour during the afternoon into the early evening hours. As warmer air worked its way into the area Wednesday night, the snow transitioned to a wintry mix especially south of the Capital District. To the north and west of the Capital District, heavy snow occurred during the early morning hours Thursday with snowfall rates of 1 to 3 inches an hour. In addition, some sleet mixed in with the snow.
A secondary low began to form in the mid-Atlantic region early Thursday morning. This resulted in a double-barrelled low pressure system which moved eastward during the day Thursday. The wintry mix transitioned back to snow which persisted most of the day. However, the snow had trouble accumulating in some locations as temperatures warmed. This limited significant accumulations from occurring across the Capital District and to points to the south and east.
