blue skies and rain

It's hot today. I check the weather forecast. It says "Rain starting in 15 min." I look outside, see blue sky with some white clouds and think that they must be mistaken.

I choose light clothes to wear, but slacks and long sleeves as we are going to the movie theater which will likely be cool from A/C.

25 minutes later it starts pouring down rain.
Ooh, and now thunder too.
