By the time fall officially begins on September 22, the Louisville area may be free of the heat and humidity from yet another warm summer, though not all forecasts indicate a break from above-normal temperatures.
According to an outlook released by The Old Farmer’s Almanac on July 11, temperatures in the Ohio Valley region, which includes Louisville, are predicted to be below average this fall.
The cooler temperatures may cause the red, orange, brown, and yellow leaves that are typical of fall foliage to appear in Louisville earlier than usual this year, in addition to the possible return of jackets and jeans.
Forecasters for the Farmers Almanac predicted that “September and October will be cooler and drier than normal across the (Ohio Valley) region,”
Forecasters predict “warm periods with scattered showers” in the early part of September. By the middle of September, Louisville might experience a cooling trend.
According to the Almanac, October temperatures in the Ohio Valley could be as low as 56 degrees, which is two degrees below average. It could be a “mix of showers and sunshine with shifting temps — warm early, cooling mid-month, then slightly warmer to end.”
