The signature reading

The question a forecast percentage cannot answer: is the viewpoint above the cloud, or inside it, right now?

The verdict above is for the next day — this reading is what the sky looks like right now, not then.

Cloud base is reported far above the 1,898 m viewpoint, around 20900 m — well clear of the summit-vs-cloud question. Expect clear air at the top.
