What happened

The episode as NWS PAH wrote it up.

Several days of oppressive heat and humidity were experienced across parts of west Kentucky. The extreme western end of the state was impacted the most. From Paducah south and west, heat indices peaked in the triple digits on five consecutive days. The highest heat indices were observed on the 14th, when values from 110 to 115 were recorded. Areas of northwest Kentucky including Owensboro and Henderson were impacted the least. At Owensboro and Henderson, heat indices peaked around 105 degrees on the 14th. Otherwise, heat index readings generally stayed below 100 in northwest Kentucky. High pressure over the Great Lakes region pushed a cold front down into the lower Ohio Valley. Heat indices remained persistently dangerous ahead of the cold front, while slightly lower values infiltrated northwest Kentucky.
