I think their 2" on August 24th 1992 is absoluetly f****** absurd. At least in June there is just enough residual wintertime cold left over at the poles to drop snow levels down to 5k feet should it be displaced south, and enough of a poleward thermal gradient still in tact to spawn strong-ish cutoff lows around the meridian line. Mid-late August is a joke of a time to get a snowstorm, even at their somewhat high elevation. They pretty much combined the strongest weather system possible at that time of year with the coldest air possible... Neither factors being very impressive nonetheless. But enough is enough. The only month I doubt they could pull off a snowstorm at all would be during July, and even then I bet the first week holds some out-there potential in the right setup. July 15-August 15 is off the table though. I think....
