Jul 11, 2020
Showers and thunderstorms developed in a warm and humid environment along and ahead of a stationary front/prefrontal trough during the early afternoon hours of July 11th. With much of northeast New Jersey receiving 2-3 inches of rain the previous day during Tropical Storm Fay, flash flood guidance values were as low as one half inch per hour in some locations, allowing the additional rainfall to result in isolated flash flooding.
