People are different. Not everyone uses weather as an entry point to other topics. Some talk about weather and just this, when in the elevator, with no intention of going forward.
This is, I believe, to cover discomfort coming from silence and such conversations, while not completely pointless, often have little value. They would talk about just anything, to combat this feeling. Weather is a good topic because most people can relate and it is rarely annoying.
I would say that both intro- and extroverts can act like this but conversations started by introverts tend to be more awkward. I think that lonely people are more likely to start valuable conversations.
I think that people are giving here genuine feedback from where they are coming from. And it looks like what you think they think is definitely not necessarily what they say they think. So unless somebody told you directly that they use the weather discussion for that reason, it could be that you value more your assumptions than their first-hand explanations...
