I love the RP around the weather. I think the improvements recently showing temperature in some places improves the player's ability to know how hot or cold your character is feeling at the moment but it could be expanded on.
I would like to suggest that when checking the weather or hearing the weather called out, the high or low is also announced. This wouldn't be the current temperature and not necessarily the eventual extreme the area you're in reaches but an overall average. something like, tonight's weather: Cloudy, low of -5C
