Weather Stats: Hot and Dry July/September, with a reprieve of cooler temps in August

The weather stats for the last few months have been all over the board here at Glen  Echo.
Hot and dry July, average rainfall in August with cooler temperatures but there were 2 events in August that made up most of that total. If I remember correctly, large accumulations at the airport with very little here at Glen Echo just a few miles away. hot and desert like September with warmer than normal temperature in October but finally some rain breaking into the 2nd week of October.
