Current is not modelled AFAIK. Easy test is to go to 'all stop' and see if you move over a few hours - my observation has been you don't.
Weather is generated through the sim. It's a subject of a lot of discussion, as the 'default' tends to have poor weather, and the conditions often don't change for days.
If you go to the mods forum you'll see lengthy discussions about changing the weather gneration.
Hope this helps.
