Torrential rain is beautiful. It reminds me of the wrath of the Greek Gods* in mythology. Sunny weather is nice, but it's a bit lame compared to the awesome power of the rain. If it's raining hard enough we get a little stream running down our drive. When the rain hits the road, the splashes get higher and higher until they are about 10cm off the tarmac. That's the best bit.
*I spell Gods with a capital G, because I don't see why Zeus should be treated as inferior to the Christian God. Apparently it's because they have multiple Gods?
