Abbotsford and Bellingham are closer and on the corridor toward the mountain, and are often clear when the coast is socked in. Anacortes and the islands see it across the water on the same days.
November through February is mostly overcast at the coast, with the mountain appearing on the clear days after a front. Sunset lights the west side, which is what Vancouver sees.

We read the cloud ceilings at the airports between Vancouver, BC and the summit, the cloud layers at the summit from the MET Norway model, and whether that cloud sits below 10,781 ft. No crowd reports.
Cloud forecasts stop being useful after about three days. A ten-day visibility forecast is a calendar with random numbers on it.
Different weather stations, different sky. The same morning can be fog in one and clear in the other, twenty miles apart. Each region page reads its own stations.
Wildfire smoke and haze can hide the mountain on a day the cloud numbers say clear. When the numbers are unsure, the page says so.
