I think this may be a little too straightforward: "It's a nice day. The clouds look nice. Now there's lightning." I'm not trying to be rude, but do you see what I mean? I would say you could try to improve it, but a haiku is such a short poem, so that may not be easy. My advise would be to just keep writing- haikus have the potential to be very expressive, it's just a matter of figuring out how to word them.
