A mid-level disturbance accompanied by a weak wave of surface low pressure passed south of the Delmarva peninsula in the early hours of February 11. Precipitation blossomed ahead of and north of this disturbance. Over the mid-Atlantic, temperatures were cold enough for this to fall as a fluffy light snow in most areas. The relatively weak nature of the system combined with considerable dry air in place limited the amount of precipitation that fell. However, good snow to liquid ratios and the predawn timing of most of the snow allowed for efficient accumulation, with a widespread area of 3 to 5 inches of snow over the mid-Atlantic and some amounts locally a little higher.
