Here's a puzzle involving yesterday's weather:
On the day before yesterday, the weatherman said, "Today’s weather is different from yesterday’s. If the weather is the same tomorrow as it was yesterday, the day after tomorrow will have the same weather as the day before yesterday. But if the weather is the same tomorrow as it is today, the day after tomorrow will have the same weather as yesterday.”
It is raining today, and it rained on the day before yesterday. What was the weather like yesterday? (Note: The prediction was correct!)
