The snow was caused by a low pressure system that moved along the southern Gulf Coast states from the morning of the 29th into the morning of the 30th. The low reformed over the Carolina coastal waters later in the day on the 30th and moved quickly northeast that evening and overnight. This prevented the heavy snow from spreading farther north into New Jersey.
