Weather Or Not

If there are 24 hours in a day how can night exist? What is the difference between a fog and a very heavy mist? What do we mean by a heavy wind? How can rain give way to showers? I’ve been told people work too long but how can you have shorter hours? We have heavy rain in the morning light rain the rest of the day, why don’t they just say we will have rain? And who weighs it anyway. The sun will break through in patches said the weatherman sounding profound, but there maybe thunder clouds overhead and I thought they’d be on the ground.
