Above normal temperatures and below normal rainfall were noted across our region throughout the summer. The warmth and dryness was the result of a persistent high in the upper levels of the atmosphere. The location of the high shifted around, but generally remained across the Tennessee and Lower Mississippi Valleys.

The remnants of a tropical system named Hermine brought copious rainfall from 3 to 4 inches across southeast Missouri and parts of western Kentucky on Sept. 9 and 10. However, the rainfall occurred within a 24 to 36-hour window. The relatively short duration of the rain limited the impact of the rainfall on drought conditions. As of Sept. 14, most of western Kentucky and parts of southeast Missouri were still designated in moderate drought. Locations further north were abnormally dry.
The forecast for the upcoming fall and early winter calls for drought conditions to persist in the same general area.
The forecast for the month of October calls for a continuation of generally warm and dry conditions. The remnants of tropical systems are not accounted for. Systems such as Hermine in early September could bring wetter than forecast conditions.
