The episode as NWS GYX wrote it up.
A very warm and humid air mass was in place over the region on the 2nd of July. Precipitable water values approaching 2 inches were common across the forecast area. Thunderstorms which formed on this day produced very heavy rainfall of 2 to 4 inches in less than 3 hours over already saturated ground. This resulted in the destruction of many roads and the flooding of apartments and residences in both Sullivan and Grafton counties.
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 Gray, ME wrote its last area forecast discussion before the first event at Jul 2, 2:26 PM EST, 29 minutes earlier.
