The episode as NWS GYX wrote it up.
Low pressure formed along the southeast U.S. coast on the morning of March 16. Strong cold high pressure was anchored over southern Canada resulting in cold temperatures over the northeast. As low pressure moved north up the coast, precipitation began as snow over Maine. By the morning of the 17th, a strong low pressure center was approaching southern New England. At this time, about 6 inches of heavy wet snow had fallen over Waldo, Lincoln, and Knox counties. However, warm air began moving inland off the water and quickly changed the snow to heavy rain as temperatures warmed from the 20s to the upper 40s in just 2 hours, melting the snow in a very short period of time. In addition, 2 to 3 inches of rain fell on top of the melting snow causing rapid runoff and much flooding. Many roads and culverts were washed out, as well as damage to some bridge crossings. A federal disaster (FEMA-1691-DR) was declared for the Maine counties of Lincoln, Knox and Waldo.
