What happened

The episode as NWS BGM wrote it up.

A slow moving storm from the Ohio Valley brought 2 to 4 inches of rain on April 2nd and 3rd. Before this storm, the rivers and streams had high flows due to a previous rainstorm March 28th and snowmelt. All towns were affected in the county by flash flooding. Roads, bridges and buildings were damaged. Numerous streams and creeks came out of their banks.

What forecasters said that day

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Apr 2, 3:15 PM EST, 5 hours 45 minutes earlier.

CONVEYER BELT OF MODERATE TO HEAVY RAINFALL CONTINUES TO STRETCH
FROM COASTAL NORTH CAROLINA NORTHWEST THRU THE FINGER LAKES AND

NEXT FORECAST PROBLEM FOR SUNDAY WILL BE WRAP AROUND PRECIP AS THE
