This is rainfall from 1895 to 2020 from the National Oceanic and Atmospheric Association (NOAA).
There are some areas of the country that are wetter than normal and other areas that are dryer than normal. This has always been going on. It changes with time.
We have been told that extreme weather events will become more frequent. There have always been wet years and dry years. And there have always been above and below average rainfall in different parts of the country and the world. Sometimes these extreme weather events last for decades or even centuries.
California has had 100-year droughts and 10-20-year droughts. And, above average rainfall. Weather varies.
The 1930’s were particularly hot and dry. There are movies and documentaries from that time that show this.
Yet, even in the hot dry 1930s there were other parts of the country that had plenty of rain, perhaps even too much.
