This is one reason why paying attention to Colorado high temps in general is misleading. It usually warms up before storms, especially in lee side banana belt regions, but unless there is a persistent high pressure anchored over us allowing the air to warm aloft over multiple days, highs around 50 at the base are still 30's up high, and that's great follow the sun skiing with snow preservation aspects holding winter snow.
Eventually sun angle wins out and the jet stream shifts north, but that's not typically until mid-May. This is A-Basin on May14 of last year:
I know this hasn't seemed like a banner year, but the snow fell in big dump cycles and it hasn't been (relatively) windy. So we are sitting on really good bases for a dead average snow year.
