Wider weather episode

A progressive upper / mid level trough lead to low pressure moving across the Ohio Valley with a secondary low developing just off the coast. Temperatures were warm and above freezing much of the time along the coast, but often at or below freezing for mainly the northwestern interior. This led to an advisory level snowfall across a good portion of Orange and Putnam counties. Also, northern portions of Nassau County on Long Island received around 3 inches.
