Just a mere two days after the 16-17th storm, this one seemed to be a redemption from Mother Nature. On the 18th of March, Nantucket had just begun to dig out of the 16th storm. Ocean Effect Snow showers developed on Thursday(the 18th), and continued into the afternoon hours. After sunset, the band of snow dissipated. This small band of snow left an inch of new accumulation.
Over the course of the night, a low pressure system moved into the Ohio Valley, and met with the northern jet stream. The Low moved off the coast early on the 19th, and experienced a slight bombogenesis. Snow began to fall early on the 19th. All that morning the snow grew in intensity, and also began to drop a few quick inches. Also that morning, high tide was around 11 AM; this as well as the combination of the northeast winds led to some minor coastal flooding, however this was confined to the Creeks.
Over the course of the afternoon, The Low continued to pull away from the coast, and the snow began to slack off just a bit. All snow came to an end by 6 PM that evening. The maximum wind of this system, was 41 mph. An unofficial wind gust from this storm system, was 50 mph. The next day, the temperature rose to 39 degrees, creating a fast melt. A warm frontal passage during the evening of the 20th, melted any remaining snowfall. As a fun side note, I went sledding wearing a T-shirt and jeans at Dead Horse Valley.
