PITTSBURGH, PA – A developing weather system could bring periods of heavy rain, thunderstorms and localized flash flooding to portions of the Ohio Valley on Wednesday, Oct. 14, as a cold front moves into the region and slows near the Ohio River.
According to the National Weather Service Ohio River Forecast Center, relatively quiet conditions Tuesday will give way to increasing rain chances Wednesday as the approaching cold front interacts with abundant atmospheric moisture.
The system is expected to affect portions of Ohio, Pennsylvania, West Virginia, Kentucky, Indiana and Illinois, although the heaviest rainfall and greatest flooding concerns are focused farther south across the lower Ohio Valley.
Heavy Rain and Flash Flooding Possible Wednesday
Forecasters expect the cold front to stall near the Ohio River around midweek, allowing showers and thunderstorms to develop across a broad section of the basin.
Rainfall could become heavy at times, particularly across the middle and lower portions of the Ohio Valley.
The Weather Prediction Center's outlook for Wednesday into Thursday identifies a slight risk of excessive rainfall in parts of the lower Ohio Valley, with a broader marginal risk extending northeastward.
A slight risk indicates at least a 15% chance of rainfall exceeding flash flood guidance within 25 miles of a location.
Despite the potential for localized flooding, the Ohio River Forecast Center expects river levels across much of the basin to remain largely unaffected.
Stronger Winds Could Follow Friday
Additional weather concerns may develop Friday, Oct. 16, as the cold front moves through and brings gusty west winds to the upper Ohio Valley.
The National Weather Service in Pittsburgh reports a 60% to 80% probability of wind gusts reaching at least 45 mph at some traditionally wind prone ridgetop locations.
Drivers should remain alert for reduced visibility during heavier downpours Wednesday and changing road conditions where water collects.
Residents are encouraged to monitor updated National Weather Service forecasts as the system develops through the remainder of the week.
