On this date in 1948, almost the entire US was over 90F, and there were 100 degree temperatures coast to coast – as far north as Pennsylvania.
Compare vs. last year – NOAA’s official hottest year ever ™. There was very little hot weather.
The frequency of hot afternoons in the US has been declining for a century, and is near a record low.
