  What happened

  Northwest Missouri suffered through two weeks of oppressive heat and humidity in late July as temperatures topped the 90 degree mark for 14 consecutive days. Dew points in the lower to middle 70s pushed afternoon heat indices above 100 degrees each day. The heat wave was most intense from July 23rd through the 30th, as temperatures reached the upper 90s or topped 100 degrees for 8 consecutive days, with afternoon heat indices between 110 and 115 degrees. Kansas City's downtown airport recorded 7 straight 100 degree days, peaking at 106 on July 29. Adding to the deadly effects of the heat was the lack of nighttime cooling, especially in the urban areas. Overnight temperatures in downtown Kansas City did not drop below 78 degrees for a 13-day period, and nighttime heat indices remained in the 80s. The heat wave claimed a total of 22 lives in northwest Missouri. Most of the victims were elderly, and 16 of the fatalities occurred in the urban core of Kansas City. The other heat-related deaths occurred outside Kansas City in Jackson County (one death), and in Cass (2 deaths), Bates (1), Buchanan (1), and Harrison (1) Counties.

The most deadly and costly flooding occurred in Jackson County where nine people lost their lives on the evening of October 4th. The Kansas City metropolitan area experienced the worst of the flooding which was similar in historical context as the devastating flash flood in September 1977. Several episodes of heavy rain producing thunderstorms commenced on the morning of October 4th and continued into early afternoon. In Lee's Summit, up to 10 people had to be rescued from a flooded apartment complex and the depth of the water on 3rd St reached 3 feet . This heavy rain fell on top of already saturated soil from rain that occurred 6 out of 7 days prior to October 4th. Shortly after 7 PM, a line of slow moving thunderstorms moved into the Kansas City metropolitan area. These thunderstorms produced 3 to 5 inches of rain in less than 2 hours in many locations. The combination of very intense downpours and dangerous lightning forced a 52 minute delay in the nationally televised Kansas City Chiefs-Seattle Seahawks football game at...
