Elevated convection developed in response to low level moisture convergence just north of a slowly retreating warm front. With very high precipitable water values in excess of 2 inches, this created very heavy rainfall rates as the storms trained over the same locations for over 5 hours. This caused flash flooding in a number of locations.
