What happened

The episode as NWS GYX wrote it up.

A rapidly developing low pressure formed off the Mid Atlantic coast and tracked through southern New England. Forcing resulted from an open wave aloft, which limited intensity and duration of precipitation. Despite a track near the coast, a seasonably cold antecedent air mass allowed precipitation to begin as snow before mixing with and changing to rain at the coast into the foothills. Precipitation stayed mainly snow in the mountains.
