Time-height omega and temperature at AVP (northeast Pa)
Notes:
The data on this slide shows NAM forecast upward vertical motion at AVP (northeast Pennsylvania) of greater than 15 µbs-1 around 00 UTC on the 17th. The strong lift extends through the lower-troposphere and into the layer where temperatures ranged from -12 to -18 degrees C (marked by yellow contours in the this BUFKIT display). This was a favorable configuration for dendritic crystal growth and heavy snow accumulations.Slide 17
