This is a poem I wrote a while ago. Using it now is probably wishful thinking as the last few days have been so hot I would actually welcome a bit of cooling rain right now.
Curtain of water,
Familiar blanket of wetness,
Grey skied creator of puddles,
Stealer of the sun;
Drowning warmth in your cold dampness,
Sliding over the street and dripping from drainpipes.
Playing on the ground.
