The weather report.....brought to you by my windcheater

I can control the weather, I can, I really can. this wasnt part of my (limited) repertoire of super powers, it is one I have acquired of late. I have this magic windcheater, it gives me the ability to manipulate the weather. I can, for instance, cause it to rain or become incessantly sunny all of a sudden . It works fairly simply.The day I want it to be sunny, I take my windcheater out of the house with me, I carry it wherever I go. The presence of the aforementioned windcheater with me,initiates a series of complicated weather patterns, preventing any sort of precipitation. On the other hand, on days when I prefer it would rain, I simply have to leave my windcheater at home, and the weather patterns reverse and it starts pouring. In fact, the greater the distance between me and my windcheater, the more it rains .I am afraid this might have had something to do with the july 26th deluge, I had forgotten my windcheater at home that day and i feel real guilty about all the inconvenience it caused, but my windcheater hadnt revealed to me its real power then.
I will not divulge anymore details though, of this hallowed windcheater, lest it fall into wrong hands.But please let me know if there are particular days, like weddings, job interviews, exams etc when you would like the weather to be of the appropriate type , I'll see what I can do, I am after all here to serve the people.
