A large, nearly stationary upper level high centered over eastern Kansas and Missouri and a dome of unseasonably warm air aloft dominated the weather picture from August 26 through August 30, 2013.  This was the hottest weather of the entire summer. Maximum temperatures soared into the 90s during much of this period with several locations reporting lower 100's on August 30. In fact, record high temperatures were either broken or tied at Cedar Rapids, Iowa and Moline, Illinois during this heat wave.  In addition to the heat, dew points were well into the 60s to lower 70s which pushed heat index values to 100 to 105, with a few locations reporting 110 degrees.  Schools without air-conditioning either canceled classes or dismissed students early. In many cities and towns, cooling centers were opened.
