A storm system pushing out of the Ohio Valley and into the Eastern Seaboard will produce numerous showers and thunderstorms today (Friday). Heavy rain is a concern, as soils are already over-saturated from rainfall earlier this week. Flash Flood Watches have been issued through eastern Pennsylvania southward along the Potomac River to north of Richmond, including Baltimore and Washington, D.C. Rainfall amounts are not expected to be as heavy as earlier in the week, but any additional rain will quickly become runoff and could lead to flash flooding. The cold front will move into the region later this afternoon and evening, bringing the highest rain threat. The system will shift into the Atlantic Ocean into Saturday morning, ending the flooding risk. For WeatherNation: Meteorologist Mace Michaels
