Here’s the deal, if you have any type of system, that is even half way decent, the whole BS sun angle crap does not matter whatsoever. October 2011 shot all that complete nonsense to the moon. It’s all about the rates…period. If it’s snowing pathetically light, then sure, you may get a quarter inch of accumulation now/in January, and it won’t accumulate in mid Feb, but is that really important? No. Who really cares about that..nobody.
The biggest/best storms/most snow comes in Feb most times…sun angle BS doesn’t factor in to that at all. Only matters in very marginal/shit systems that aren’t worth the effort anyway.
