A ridge of high pressure aloft over the plains allowed a prolonged period of hot and very humid conditions to persist across eastern Nebraska and southwest Iowa for a large part of the second week of August.  Daytime highs over much of the area reached the 90s with dew point temperatures often in the 75 to 80 degree range.  This created heat index values that often reached around 105 to 110 degrees and sometimes 115 or hotter.  The highest heat index values during this period were near and south of Omaha toward Falls City and then into extreme southwest Iowa where afternoon values often reached 110 or higher during this stretch.  Several episodes of thunderstorm activity brought temporary relief to some areas during this stretch, mainly to northeast Nebraska.
