The episode as NWS PBZ wrote it up.
Extreme cold arctic air surged into the northeast region January 30th. 500mb heights were close to 5040 meters, 850mb temperatures ranged from -26 to -30 degrees Celsius, and 925mb temperatures were near -22 to -26 degrees Celsius. With the quick drop in temperature in the boundary layer, a steep low level lapse rate was created near the surface. Due to this steep lapse rate, winds near 850mb to 925mb (averaging 20kts) were capable of reaching the surface and created wind chill temperatures of -22F and lower.
