After an excessively wet start to the year, a drier weather pattern abruptly took hold of our region beginning the last 5 days in August and continued into early October. This was the worst drought to affect western Kentucky since November 2016. September was a very dry month, particularly across western Kentucky, southeast Illinois, and southwest Indiana. Several locations observed their driest September on record, including Evansville, which received a whopping 0.08” the entire month! There were numerous locations that received a tenth of an inch or less, especially in the northern Pennyrile region of western Kentucky. The streak of 12 consecutive months with above normal precipitation came to an abrupt end in Paducah, as we only picked up 0.32”. This was the 4th driest September on record in Paducah, and the driest month since October 2005.
Paducah went 29 days without measurable rain from August 27 through September 24. This was the longest dry spell since September 1999 and the 8th longest dry spell on record, dating back to 1937.
The graphic below is an interpolated rainfall map using actual observations. Please note that there are likely discrepancies in between observations, since the values are estimated based on nearest reports. (Ex: Estimates in Bollinger County Missouri appear too high, but we have no observations from that county.)
