The idiom is mostly used in the United States and Canada. It is an informal term that is not used in any sort of formal setting.
The phrase originated during World War II. It is a play on the idiom "snowed under" which means to be covered. It is often used to describe a feeling of helplessness when you are overwhelmed. For example, when someone is snowed under with work.
Both idioms can be related to a large amount of snow fall. It covers everything in its path and hides it from sight.
