Summary: For decades, research has suggested that climate change will lead to new drastic weather patterns. Recently, a new study has come to surface further investigating the implications of intense precipitation patterns, but with regional variations. The study was conducted by the National Center for Atmosphere Research. Led by Andreas Prein, the researchers divided the United States land mass into 2.5 mile square grids and utilized computer simulations to look at extreme precipitation patterns in hour increments. The precipitation data ranged from 2000 to 2013.

The data published was alarming. Researchers found that rainstorms may become more frequent and intense if greenhouse gas emissions remain at current levels. The biggest rainfall increase is projected to be in the Northeast and Gulf Coast.

Other areas, such as the Pacific Northwest, already rainy and humid as it is, found that it might become drier on average, but more intensified extreme rainfall. Thus, more risk of droughts and of flash floods.
Another area of concern is the Midwest, where it could seem that these conditions could alleviate drought events occurring there. However, this extreme rain can have a reverse effect, causing soil erosion, and washing away plats that assist in absorbing soil moisture.
