An unusually persistent upper level ridge of high pressure centered near and over the Tennessee Valley caused a prolonged period of record to near-record heat and dry weather throughout Middle Tennessee from September 2019 into early October 2019. This heatwave set new records for warmest September ever at Crossville and second warmest September ever at Nashville, as well as the hottest temperatures ever observed in the month of October at both locations. In addition, the lack of rainfall in both Nashville and Crossville made September 2019 the driest month of September ever since records began. Interestingly, this occurred only one year after the very wet month of September 2018, which was the #7 wettest at Nashville and the #1 wettest September ever at Crossville. In addition, although 2019 started off extremely wet with record rainfall and flooding in February and March, the lengthy dry conditions in September and October created moderate to severe drought conditions across the entire region, with several brush fires reported in late September and early October. Thankfully, much cooler and wetter weather arrived by the second week of October, ending this period of record heat and dryness.
