For the remainder of this evening and into the overnight period, a couple additional rounds of showers and thunderstorms are anticipated. The first is moving into portions of southeastern PA and northern Delaware now, and should continue spreading east. An additional round is possible overnight, but less confidence on that. The main threat with the activity tonight will be locally heavy rainfall that could lead to flooding, as well as frequent lightning. The severe threat has diminished from earlier today, however we cannot rule out an isolated severe storm through the night. Tuesday's thunderstorms are expected to be more widespread than today's and more organized in nature. Potential impacts from thunderstorms tomorrow will include damaging winds and flash flooding. Remain alert for changing weather conditions through Tuesday, and have multiple ways to receive any warnings that may be issued!
