A warm front approaching the area combined with a strong low level jet ushering in precipitable water values in excess of 1.5 inches, resulted in flash flooding across parts of northeast New Jersey. Newark Airport (3.05 inches) and Teterboro Airport (3.01 inches) received just over 3 inches of rain during the event, with the majority of that rain falling during a three hour period. Hourly rainfall rates of up to 1.5 inches were reported at Teterboro, with rates over one inch per hour at Newark.
