Notes:
This NAM forecast sounding valid at 20z at BGM in central NY indicated the development of substantial instability with MLCAPE values exceeding 2000 J/kg, however the dry mid-level air is also quite evident. A layer of very steep lapse rates can be seen at the bottom of the dry layer around 700 mb, contributing strongly to the instability.
