One answer per mountain, per region, from the airport weather stations along the sightline and the cloud layers at the summit. Not a crowd poll. It computes, so it works at 6 AM when nobody has looked yet.
All four mountains, a push when yours comes out. $0.99 once.

Every mountain page reads the cloud ceilings at the airports between you and the summit, the mountain's own cloud layers from the MET Norway model, and whether the deck sits below the summit. Low cloud and high cloud are scored separately, because a cirrus sky and a stratus lid can add up to the same "60% cloud" and mean opposite things.
Forecasts stop at three days. Beyond that a cloud forecast is a guess with a date on it.
Mountain Visibility Forecast carries all four mountains. It picks the nearest one by where you are, reads your part of the region, and sends one push when the mountain comes out and one when the light is about to be good. Two a day at most, never at night.
