The historic heat wave that began in late June continued into July. This heat was comparable to the intense heat experienced in the 1930's. The high temperature reached or exceeded 100 degrees on 9 out of 10 days going back to June 28 and ending on July 7. At Paducah, the high of 107 degrees on the 6th was one degree shy of the all-time highest temperature recorded there. The all-time record at Paducah was first set on July 17, 1942 and tied on June 29, 2012. Daily high temperature records were broken on six of the first seven days of the month. New daily records were 105 degrees on the 1st, 101 on the 2nd, 101 on the 4th, 105 on the 5th, 107 on the 6th, and 104 on the 7th. From the 1st to the 6th, humidity levels were not especially high due to the ongoing drought, so heat index values were close to the actual temperature. Higher humidity on the 7th and 8th raised peak heat index values to between 106 and 113 degrees. Strong high pressure aloft remained anchored over the middle part of the country through the first week of July.
