Severe Thunderstorms and Heavy Rain Across the Ohio Valley;

Severe thunderstorms with damaging wind gusts will be possible from the mid-Mississippi Valley into parts of the Ohio Valley and central Appalachians. Heavy rain associated with these storms may lead to considerable flash and urban flooding impacts across portions of the Ohio Valley. Mid-summer heat persists from the Central Plains to the Southeast. Read More >

September 2015 was a seasonably quiet month with almost no stormy weather (the exceptions being a weak downburst in Saint Matthews, KY, on the 1st, and a few trees down around Henryville, IN, and Frankfort, KY, on the 5th). Dry conditions prevailed for the first week of the month, followed by some wet weather from the 9th to the 11th as a couple of slow-moving cold fronts crossed the region. A longer period of dry weather then settled in for much of the rest of the month until the final couple of days when an upper level disturbance combined with a surface cold front to produce widespread light rain.

Temperatures were generally seasonable with no extreme heat or cold.
