A low pressure system, moving slowly through the Great Lakes, pushed cold front into Central New York. This frontal boundary became stationary over the area, and was followed by an area of rapidly deepening low pressure moving north along the spine of the Appalachian Mountains. Tropical moisture was ingested into the frontal system which triggered several hours of moderate, to occasionally heavy rainfall. This led to areas of minor flooding and ponded water in typical locations.
