I was going through the same thing. I don't know for certain anymore if it affects the weather but I know since I have been chanting Hare Krishna that I am losing attachment for my physical body so I don't really feel affected by changes in weather even if the weather goes to extremes. I think chanting the Hare Krishna mantra makes you more sensitive to what is happening in the universe and consequently you may notice things more closely than somone who is struggling with their fear of annihilation. Not everyone is experiencing the weather in the same way.
