Summer Rains, You can Never Predict Them

For the title I quoted Double D from an episode of Ed, Edd & Eddy.
It literally rained for two weeks straight, all the way through. Luckily most
of it was not heavy rain, the sky was gray and the rain was barely a drizzle so
it was not so bad. And yesterday it stopped raining, Mr. Sun came up and smiled at me,
and it was nice and clear outside but it was so hot! And then today when I thought the rain was over for a
while, it stormed a little with the thunder and the lightning and all that good stuff. Talk about "
You can never predict them". I think the rain is finally over though. But normally summer rains do one of
two things (or both): They either leave the air dense and humid for a few days, or the weather is a little
hotter for a few days [or both].
Why am I talking about the weather?
