Discussion
There is a good chance for significant rainfall in the Mid-Atlantic region during the next 48 hours as a cold front inches its way across the area and localized flash flooding is a concern. This cold front will have support aloft from a strong disturbance that will center itself over the Great Lakes/Ohio Valley and there will be plenty of low-level moisture within the broad south-to-southeast flow of air that forms today on its front side. Occasional showers are likely today with an afternoon thunderstorm possible and they will become more numerous for tonight, tomorrow and tomorrow night. Some of the thunderstorms on Thursday and Thursday night can reach strong-to-severe levels. Following the frontal passage, the weekend is looking quite nice with comfortable temperatures for late September.
