The episode as NWS OKX wrote it up.
Several waves of low pressure rode along a slow moving cold front approaching the area on July 23. A tropical airmass was already in place across the local area from Tropical Storm Cristobal which passed by to our east the previous day. The combination of these systems interacting with this airmass led to torrential rainfall and flash flooding.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before the first event at Jul 23, 9:55 PM EST, 35 minutes earlier.
