There may be some much-needed relief from this unusual heat wave soon.
First of all let me explain the unusual part. If you've lived in St. Louis for any length of time you know that sccessive days of 90+ temperatures is nothing unusual here in the Summer. But normally these heat waves take place in July and August. The longest successive 90+ heat wave is 28 days long! (it ended on July 30, 1936).
