Meteorological autumn began last Monday, but as usual in early September we slouched through some sticky heat most of the week. Then Friday the weather broke, and this past weekend's weather was spectacular.
Partially because the lake was so cool from last winter, this summer we had only three 32°C days—fewer than in any year in history except 1979.
It gets better (i.e., cooler). The forecast calls for slightly-above-normal but comfortable days today and tomorrow, followed by a cooling trend taking temperatures down nearly 9°C by Friday. Because this is Chicago, where we go from shorts to jackets in less than a week.
Unfortunately, I'm going to spend tomorrow in Phoenix and Wednesday in Louisville, where it will be ghastly warm. Oh well.
