Depending on your location, you either picked up a few hundredths of rain, if any at all, or as much as one half inch or more, in some of the heavier showers and thunderstorms that rolled across the region Monday evening. At Barkley Regional Airport, prior to the rainfall Monday evening, only 0.60 inches of precipitation had been recorded for the month of September. That was on target for the 4th driest September on record. However, 0.43 inches of rain Monday evening bumped the monthly total up to 1.03. Not enough to keep the monthly total out of the top 10 driest Septembers on record (8th driest, with no more rain expected). The normal for the month is 3.56.
Similar story at Evansville Regional Airport. Prior to yesterday evening, the monthly total at Evansville was 0.79. That total was on pace to be just outside of the top 10 driest Septembers on record (dating back to 1896). Monday evening, 0.37 inches was measured, which brought the monthly total up to 1.16. While not a top 10 finish, it will be below the monthly normal which is 2.99.
