Snowstorm Dec 11-12th, 2016

Epilogue;

While models diverged some early mid-stream they came together for the heavier scenario of snowfall which I forecasted early on the 10th. I updated by just an inch on amounts on the plus side 12/11 and very happy with the results. This storm was odd in the sense that generally these type of long duration, weak low situations may deposit 4-6" of light snow. It definitely was an over-achiever for it's dynamics and surface features but shows you what you can get with moisture rich atmosphere, good forcing (old school, overrunning) and multiple pva's. The system actually had two warm advection pva's; one early in the game along the waa and one later with low and warm front...which gave her the added boost to achieve.
