This is the fifth in a series of ten posts that present graphs of NOAA precipitation, drought (Palmer Drought Severity Index, PDSI), and temperature (TMIN, TAVG, and TMAX) data for the contiguous United States (and the 9 NOAA Climate Regions thereof) for the most-recent 100 years (1919 to 2018) of data that were available at the time that I prepared my paperback book Extremes and Averages in Contiguous U.S. Climate, which is the source of the graphs. That book was first published in May 2019. The subtitle of the book isGraphs of 100 Years of NOAA Contiguous U.S. Climate Data (2018 Edition) – A Book That NOAA Should Have Published.
