Summer Precipitation Trends

Summer precipitation trends are not quite as distinct as summer temperatures. As both evaporation rates and heavy rainfall events increase in a warming world, this lends itself to bigger variations in precipitation. While there will be some exceptions, wet areas generally get wetter, and dry areas generally get drier.

For example, despite the 5-year drought that was recently busted in Oklahoma, most of that state has an upward trend in summer rainfall, further indicating the feast or famine that can come with rainfall in the Plains. Summer is also the rainy season in Florida, and parts of Central Florida have seen an increase of 0.4” in summer rainfall per decade since 1970.
