The Eye of the Storm

I took this photo yesterday, just as a storm was about to hit. (or so we thought. Instead it was more like the weather equivalent of being bursting to go to the toilet, and then when you get there it's just two drips.) Anyway, I thought this had some nice contrast and I really like the granite grey clouds on the edges. I haven't figured out a hidden meaning behing it yet though. Anyone want to help me out?
