For a UK audience the inclusion of a 3800' cloudbase forecast in several of the examples is deeply unconvincing - that would rank as the 'best day of the year' here!
It's also deeply unlikely in UK that a 3800' forecast would turn into the sort of weather depicted here, unless crossing high ground or someplace unrelated to the forecast.
On the other hand I found the visuals quite realistic and comparable with the 'turn back now' sort of scenarios that are familiar here when a 2000' cloudbase is regarded as a gift from heaven.
I suspect most of my answers were based on the percieved granularity of the surface.
