I think it's somewhat wet snow (even at altitude), and thus might be able to help them open sooner, but by itself probably will not be quite enough. They are not providing much of any updates because of power & internet outages. You'll note that Abasin for example has gotten only one web cam working so far this morning (all of them went offline at like 2am). I know I70 shut briefly at some point last evening too.
As you note, this is very early season for such a snowfall. While it will warm up, right now I only see two days of warmish temps in the 10 day (the weekend). I know the N facing stuff is already holding snow OK from the, thus far, minimal snowmaking that had been done. So it'll be the flats and non-N facing stuff that will be the biggest issue.
