Earlier versions of the laser-guided and GPS guided systems could be effected by the weather, but so are the planes that they are flown on. However, since other countries know that we have these weapons, other countries (friendly and unfriendly) expect us to hit the right targets, but sometimes we miss and hit civilians and it makes us look bad.
Clouds deflect the laser that is produced by the guidance system and so that the missile might go off in a totally different direction.
