Dangerous heat persists in the South and Southeast while building into the Southwest. Overnight lows will be so warm that little-to-no relief from the scorching daytime highs will be available.

September was a warm and dry month this year, with mostly uneventful weather. The generally warm and dry conditions led to moderate drought developing by the end of the month across most of southern Indiana and in central Kentucky roughly north of a line from Hardinsburg to Columbia to Richmond.

There was one severe thunderstorm event during the month, though, when an upper low crossing the Midwest and a surface low over southern Illinois brought a round of severe storms to Hancock and Breckinridge Counties between 9:30pm and midnight on the 27th. Unfortunately one of the powerful storms contributed to two fatalities when an 18-year-old student pilot and his 22-year-old instructor flew too close to the storm and crashed in a forested area south of Whitesville near the Ohio/Daviess County line. Another storm that evening produced a 71 mph wind gust and blew trees down in and near Hardinsburg.
