A warm front stalled along the northern Massachusetts border. Low pressure moved from the Mid Atlantic states up across Southeast Massachusetts during the night of the 18th and early morning of the 19th. High moisture values in place south of the warm front and a low level jet to generate lift over Southeast Massachusetts led to a period of torrential downpours from New Bedford to Outer Cape Cod.
