Meanings and origins behind weird weather phrases

Have you ever wondered where weather terms like "raining cats and dogs" came from? Turns out these weird weather phrases have an interesting history.

The origin of "the tip of the iceberg" is based on how most of an iceberg is below the water. "Cloud 9" may refer to the 9th cloud, a cumulonimbus, the biggest, fluffiest, most comfortable cloud, according to AccuWeather.

"As right as rain" was first recorded in late 19th century Britain, and refers to the pleasant nature of rain. "Raining cats and dogs" is speculated by some to have originated during 17th or 18th century England, where heavy rain would wash dead cats and dogs down the street.
