Overview and Graphics

Temperatures averaged near normal to slightly above normal across the Quad State. The warmest stretch of the month occurred from the 19th through 21st when record highs were established at several locations. Temperatures soared to 100 degrees at Paducah and Cape Girardeau on the 20th and 21st. This was the latest occurrence of experiencing triple digit temperatures at both locations. September 22nd was the first day of the month observing highs below 80 degrees in Paducah and Cape Girardeau. The month ended with below normal temperatures from the 26th through 30th as lows routinely dipped into the 40s and highs were only in the 60s and 70s. Some locations even dropped into the 30s on the mornings of the 27th-30th.

The vast majority of the region experienced an abnormally dry month, and 4 of our 5 climate sites observed one of their top 10 driest September’s on record. Many areas struggled to pick up more than 2” of rain the entire month. This was especially true across southeast Missouri, the Jackson Purchase area of western Kentucky, and far southern Illinois where many areas only received 0.5” to 1”. Monthly rainfall deficits of 1 to 3” were commonplace. The exception to the dryness was across the Evansville Tri state where localized amounts exceeded 6” for the month. This was primarily due to heavy rain that occurred on September 3rd, which lead to Evansville experiencing their wettest September day on record with 4.48” of rain (3.22” occurred in 32 minutes and 4” occurred within an hour that afternoon)! This was Evansville’s wettest calendar day in over 8 years, since picking up 4.96” on April 3, 2014.
