Wider weather episode

A mid level disturbance associated with a confluent upper level trough lead to strong mid level frontogenesis that developed a band of snow to the north of developing low pressure moving offshore. Southwestern portions of the area were on the northern edge of a narrow band of heavy snow that resulted in some southwestern zones reaching warning criteria. Amounts were considerably less to the north.
