September 2020 Climate Review: Temperatures finished near to slightly above normal. The first 2 weeks averaged warmer than normal while the last 2 weeks of the month flipped to cooler than normal. Paducah observed 4 straight days in the 90s from September 8-11 and exceeded 80 degrees every day for the first 17 days of the month. The pattern flipped on September 18, with upper 60s and 70s for highs occurring much of the rest of the month. Lows dipped into the mid 40s to low 50s on many nights over the final 2 weeks as well.

September was drier than normal across the majority of the region. This was most pronounced across northern portions of southern Illinois and southwest Indiana, where many locations only picked up 0.5” to 1” for the entire month. By the October 1 drought monitor update, abnormally dry conditions (D-0) had developed along the I-64 corridor. There were exceptions to the dry conditions though, with southern portions of southeast Missouri into parts of western Kentucky registering a wetter than normal September. This included Paducah, which recorded nearly 5 inches.
