Haibun-Haiku: A rumble echoes in Las Vegas

a rumble echoes

charcoal clouds conceal the sun

an afternoon storm

I heard a rumbling and looked out my living room window to see charcoal gray clouds covering the sun. I think it is going to rain. I listen to the noon news, the meteorologist said it might rain, but I do not remember if he said a 30% chance of rain or a 40% chance. It is days like this that make me happy I do not hang my wet clothes outside any more. I do not see or hear rain yet, but I expect it to start raining any time.
