Yeah 72 hours of teens would do it.
That extra 500 verts makes a lot of difference… so often snowmaking gets to 2,500-2,000ft this time of year then stops.
I want to see 850mb temps under -10C for like three days.
1500ft is also mid-slope climate and like Kevin’s yard… the surface inversion is below that usually. So we get nighttime profiles where it’s like 24F in town, 34F at 1500ft, and 24F up top.
It’s a challenge to get all 2,100 verts sufficiently buried this time of year without some legit cold. It’s always fine on the top 1000-1500 feet.
