The episode as NWS OKX wrote it up.
Low pressure developed across the southeast on Sunday March 3, 2019 and then tracked off the Middle Atlantic coast early on Monday March 4, 2019. The low moved just inside the 40N/70W benchmark and continued out to sea. The low brought a widespread snowfall to southeast New York with the heaviest accumulations occurring across the Lower Hudson Valley. Snow mixed with rain and sleet occurring near the coast, reducing accumulations. Much of the significant snow occurred overnight with improved conditions during the Monday morning commute.
