Threat for Flooding from the Jersey Shore to the Central Plains
Heavy rain has been falling across the Ohio Valley and more is ahead through the middle of this week. Some areas saw more than 4″ of rain on Sunday and an additional inch or two Monday. With more rain in the forecast, flooding is possible. Flash Flood Watches extend from the Jersey Shore through the Ohio Valley and into the central Plains.
Over the next several days, more than 5″ of rain could fall from the Northeast to the Plains. With the ground already saturated, additional rounds of showers and embedded thunderstorms through Friday could result in flash flooding. Some locations could have rain repeatedly move across spots which have already received up to 2 to 3 inches of rain in the past several days. This may result in flooding even with lighter rainfall amounts than would otherwise be expected.
Humidity remains high across the region with southerly winds increasing dew points and moisture from the Gulf of Mexico. A stalled front will barely move through the middle of the week, aiding to produce several rounds of showers and thunderstorms. With persistent rain and pockets of heavy storms, the flooding threat will continue.
