JULY 1999 Great Plains Heat Wave


After a relatively mild start to summer, a heat wave spread across the Great Plains beginning in mid July.  By the end of the month, many locations in Nebraska had reported over 20 days of temperatures exceeding 90 degrees Fahrenheit.  The heat wave peaked in Nebraska on July 29 with afternoon air temperatures above 100 degrees across the state.  It reached 104 degrees in Lincoln, 1 degree shy of the all-time record high for the date.  However, the high humidify made these temperatures feel even more unbearable as the heat Index moved into the "Danger" levels.
