Its different every year. No one on here can give you an answer that's i not completely pulled out of their ass. And anyone who thinks they can is stoopid.
the real question is, why the hell are you skiing summit? the only part of snocompton worth riding is the alpy BC when its very cold and has snowed a good amount
Ignore mrstskier... Alpy BC sucks. It's crowded and um, unpatrolled. Don't go there. There's never powder. stop thinking about it. Stay in the park trust me.
believe me, I wish i could ski another mountain, but I don't have much money for a seasons pass to stevens or crystal. Baker would be tight but the gas money to get up there on a regular basis would just be too much
december probably but its possible to happen earlier climate forecasts call for a increase in percipitation by november and a cold trend kicking in in december
