What happened

The episode as NWS PBZ wrote it up.

Strong cold advection behind a cold front brought in much colder air on March 10th. Steep lapse rates and marginal instability led to the development of snow showers and a few snow squalls that morning. More numerous snow showers continued into the overnight hours, resulting in some accumulations, highest north of I-80 and along the ridges. Also, the steep lapse rates, strong surface pressure gradient, and strong pressure rises behind the front led to a period of strong wind gusts, topping out in the 45 to 58 MPH range.
