Showers and thunderstorms developed during the afternoon across northeast New Jersey ahead of an approaching backdoor cold front. With relatively weak flow aloft, these storms moved slowly, resulting in heavy rain across some areas. CoCoRaHS observations indicate a widespread 0.5-2 inches of rain in areas that received storms, with the ASOS at Teterboro Airport reporting 2.89 inches of rain. Much of this rain fell over a 1-2 hour time period, resulting in flash flooding.
