Contest # 4 - Teleconnections

So much for the conventional wisdom about needing +PNA...-AO...or -NAO to get good snows in the NE CONUS.

AO for this historic snowstorm...where six daily snowfall records were more than 2 standard deviations above normal. NAO is +1.5 STD and PNA is normal.

Everything else being equal...all you really need is amplification of the long wave in a ridge-W and trof-E flow regime. Shorten the wavelength and Sutcliff/s self-development process kicks in...which takes care of the rest.
