Beneficial rains swept across much of the region in September, especially in southern Indiana and northern Kentucky where drought conditions had been at their worst over the summer. On Labor Day weekend the remnants of Hurricane Isaac came through and dropped general amounts of 1 to 3 inches across the region. Additional wet systems followed through much of the month, including a stretch of four consecutive wet days from the 25th to the 28th that resulted in 2 to 4 inches of rain along and about 35 miles either side of the Ohio River.
Severe weather occurred on only two days during the month. On the 5th a squall line developed from southern Indiana to western Kentucky and swept southeastward during the afternoon, producing strong gusty winds. On the 7th another squall line developed during the afternoon hours, this time from Indiana to Arkansas. Though the line weakened as it entered southern Indiana and central Kentucky it still managed to generate strong gusty winds.
The first cold snap of the fall season occurred on the 23rd-24th as temperatures fell into the 30s under a strong dome of Canadian high pressure. It gave Lexington the city's earliest frost (36 degree temperature) on record.
