I am not sure how feasible or codeable this is. Control weather currently only affects 'better' or 'worse' for the weather. One, however, cannot change the temperature (Cold, hot, mild, etc). I was wondering if at higher levels of the spell, one might be able to make it 'colder' or 'hotter,' as well as better or worse.
