By any chance could you add a map with the standard deviation of the map graphics which show average values?  (Departure from normal precipitation, departure from normal average temperature, and so on)?  The SD would serve to illustrate some context behind the averages presented above.  Averages are worthless (I’m so mean!) without the context provided by knowing how relatively “tight” those departures from the mean are.  Or, as a philosophical genius once put it, “Everything is relative, and nothing is absolute.”  
 

One final note, I would like to see a “snowfall avoidance” number.  As temperatures have trended upward, where I live we have experienced much less snowfall when the precipitation instead falls as rain.  It sounds like a heavy, heavy lift to analyze this, but I am curious.  Also as precipitation events have grown more intense, the inverse may also be true; how much worse have snowstorms gotten as the weather trends farther from average?
