I'd bring both if you can. When it gets slushy/sticky I think pow skis are more fun b/c they are less likely to catch an edge and are more surfy.
I'm guessing it is sticky up there right now as I type this. Snow will get cooked again tomorrow. After that I don't know. Hard to predict more than 3-4 days out but the 7 day is showing a chance or precip.
