Sunday Overview: Tropical rains, flooding likely again
Tropical moisture and just enough lift combined to support the development of torrential rains on Saturday, with localized flash flooding reported both in New Jersey and throughout the Mid Atlantic. Much of the same is forecast on Sunday, with a warm front nearing the area during the afternoon. This may be particularly true across Northeastern New Jersey, where a convergence zone will allow for moisture to “pool” along a frontal zone.
This allows for a few things to occur, but most notably, it juxtaposes lift and moisture to develop torrential rains. With plenty of anomalous moisture still available throughout the area, the recipe could be there once again for flash flooding in localized areas. Upwards of 2″ of rainfall in relatively short periods of time could cause problems, especially in flood prone areas.
