Physically, the only thing holding us back from manipulating the weather is understanding the exact method that weather patterns form. There's a lot of randomness involved, but if you knew enough about what is really going you could nudge things in the right direction.

All of the sudden, the 10th Mountain Division makes a hell of a lot of sense; "the only one of its size in the US military to receive intense specialized training for fighting in mountainous and arctic conditions." Sorry for the Wikipedia link; I know they're not the best but my wheels are turning.
