Csnavywx,
Of course, I concur with your analysis tying the low NH snow cover to our current Super El Nino and I add the following info. Furthermore, I note that most people only see El Ninos as parts of the natural ENSO oscillations; whereas I see them triggers that can help to ratchet up other positive feedbacks, not only including NH snow extent, but also positive cloud feedback, positive PDO and increased water vapor in the atmosphere:

A Duluth, Minnesota, newspaper reported that the temperature was 40 degrees above zero, not below. And in Miami, beachgoers are staying indoors during what's already the third-wettest December in local history. What's going on with the weather?
It's the phenomenon called El Nino, which is happening now as ocean water temperatures rise above normal across the central and eastern Pacific, near the equator. Its effects will leave the U.S. Northeast warmer than usual, the Midwest drier, and the West and the South wetter."
Best,
