I was thinking about this last evening. Many of us on here are model followers and then weather spotters when the event happens. Frankly we can (and quite often do) forecast snow storms, for our local area, better than professional mets and NWS offices. But when the snowstorms end we go back to our jobs and do not have to forecast the mundane 250 days a year that the mets do. It is then that they have to use climatology and analogs a lot more as there are hundreds of sunny days each year. Each of these snow storms is unique in some manner and requires leaning on guidance because any analogs are questionable at best.
