Storms to Rattle Nashville to Cleveland, Pittsburgh Wednesday
May 15, 2014; 4:28 AM
Another round of strong, soaking storms is set to slam part of the South and Midwest into Wednesday night. The storms will bring the risk of flash flooding, damaging wind gusts and isolated tornadoes.
Cincinnati; Cleveland; Pittsburgh; Buffalo, New York; Louisville, Kentucky; Nashville and Memphis, Tennessee; Tupelo, Mississippi; and Birmingham, Alabama, could all be rattled by powerful thunderstorms, especially during the afternoon and evening on Wednesday.
Flash flooding could be the most widespread impact as drenching downpours dump as much as 1 to 2 inches of rain in less than an hour from the upper Gulf coast to the lower Great Lakes.
Such a substantial amount of rainfall in such a short amount of time can cause water to pool on roadways, resulting in treacherous travel for anyone attempting to drive through the blinding downpours.
Localized power outages may occur as these storms blast through with wind gusts strong enough to bring down tree limbs and power lines.
A few isolated tornadoes cannot be ruled out in the strongest storms with the greatest tornado risk covering an area from eastern Mississippi to central Kentucky.
Thousands of baseball fans in Cincinnati could face a rainout on Wednesday evening as the Reds are scheduled to host the Padres at the same time that the steadiest rain is forecast to spread over the city.
Other outdoor activities planned across the region on Wednesday may also face a washout with thunderstorms being followed up by a steady rain that will last into the night.
An area of drenching rain will expand north and west of the thunderstorm zone.
According to AccuWeather Meteorologist Mark Mancuso, "Chilly rain will extend from the Lower Mississippi Valley to the Lower Ohio Valley into Wednesday night."
Downpours and gusty thunderstorms will be replaced by cooler, less humid conditions for Thursday and Friday, although a few showers may linger around in Tennessee and Kentucky.
Thunderstorms and flooding downpours will shift eastward Thursday and Friday.
According to AccuWeather Senior Meteorologist Alex Sosnowski, "Converging moisture from the Central states, the Gulf of Mexico and the tropical Atlantic will raise flash and urban flooding concerns over a large part of the Appalachians and in a portion of the Atlantic Seaboard to close out the week."
