August 24th afternoon temperatures have been declining in the US for a century, as has been the likelihood of hot weather.
This date in 1922 and 1936 brought temperatures over 110 degrees to the central portions of the US.
Prior to 1950, hot weather on August 24th was commonplace in the Midwest, but rarely happens now.
