Actually, regarding the weather thing.
That's MORE OR LESS a thing that doesn't happens on most cutscenes, I do remember the more recent quests absorbing the weather of the surrounding area, or at least a few of them (the 1.22b quests, I did one of them in a sandstorm, damn cool).

However, making sure that every cutscene uses the proper weather would be pretty nice, except in those cases where the weather is important to the scene itself, one can handle a bit of suspension of disbelief for a proper setting tone.
