Rob: It really depends.
1. When you want to describe the weather where the characters are, roll. On a success, say what the weather's like there. (On a failure, it's 76°, few clouds, with a pleasant little breeze.)
2. When your character's taking strenuous action, if it's oppressively hot where your character is, you get -2 to your roll.
That's boxes to cloud, then cloud to boxes.
1. When you want to give another player a die penalty, make a roll. On a success, a) say what's making life hard for their character, and b) give them a -2 to their roll.
That's a) boxes to cloud, with a simultaneous b) boxes to boxes.
(So, Guy: no, it doesn't count as a rightward arrow.)
In case 1, the more time and conceptual space between those two rules' applications, the more real the oppressive heat will seem. For instance: you make a weather roll at the beginning of the session, declare that it's oppressively hot, and so for the entire session all the players roll -2 for all their characters' strenuous actions.
