    Those spots that you're seeing are not rain. They are where the National Weather Service has its Doppler Radar Stations. The spots you are seeing are just random scatter that the radar is picking up on since it is near to the radar. The scatter could be dust and other small debris, even insects.

    The bands that you are seeing that have the yellow coloring that are moving is the actual precipitation which is circulating around a low pressure system.

    Well each part of the U.S. has a different climate. Take Nevada for example, it's a dry environment. Florida, which has an opposite climate will have more annual rain than Nevada. Also, you wouldn't think that when it rains, it rains everywhere in the U.S., right?
