Historically Extreme Summer Warmest Maps

The first map below show the local warmest June-August period on record across the CONUS. The five largest footprints, which aren't necessarily the five warmest years overall, are depicted in unique colors; all other Years are combined into an "other" category. The other maps depict the same type of analysis, for: minimum ("overnight low") temperature, and maximum ("afternoon high") temperature.
