Discussion

The combination of very moist air, a strong and slow-moving upper air system and a stalled out surface frontal system will generate numerous showers and thunderstorms today and tonight throughout the Mid-Atlantic region and some of this rain will fall heavily at times. The potential exists for renewed localized flooding problems over the next 24-36 hours given the already saturated grounds and the expected new rainfall of up to 2 or 4 inches or even more in isolated spots. Do not drive through flooded roadways. This prolonged unsettled weather pattern will continue right into the middle of next week thanks to the stubborn upper air system that will only crawl to the northeast coast from the Ohio Valley. On the positive side, this same vigorous upper air low that is causing our unsettled weather pattern will likely keep Tropical Storm Ophelia out to sea as it should eventually make a turn away from the east coast before ever making landfall.
