A boundary was stalled over western Middle TN in a very humid air mass, which was the focus for continuous and training thunderstorms for several hours.

Someone else might come in with a better meteorological explanation.

I will say that I noticed at the time that Henri was out in the Atlantic moving northward toward the Northeast. I was wondering at that time if it could have been an indirect factor and put the breaks on features moving through the US. A Bermuda high or ridge to the east can do that too, though.
nailed it man… bingo

Not the 17 inches but the heavy rain was forecasted. It actually set up a little east of the forecast. Dyersburg was in the bullseye but only received a couple of showers.

OHX was on it 48 hours in advance.  They were eye-balling the Tennessee River corridor as ground zero.  The amounts, each subsequent model run, were increasing.  To say they were concerned would be an immense understatement.

That's great to hear. I hope some of the folks knew in advance. I'm certain OHX saved lives.
