['When I was driving home from work the other day I saw a lot of very dark clouds in the sky.', 'Maybe it was a thunderstorm forming??', 'How did you guess? I was guessing that a thumerstorm would arrive with lots of rain. I was right when it started downpouring a few minutes later!']
It souds like a storm forming.I have experience with thunderstorms.
On my drive home from work I noticed there were a lot of dark clouds rolling in. Usually this means there will be a lot of rain. I anticipated thunderstorms and was right.
