What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Nashville, TN wrote its last area forecast discussion before this river flood warning went out at Aug 31, 7:30 PM CDT, 1 hour 18 minutes earlier.

Area forecast discussion, Aug 31, 7:30 PM CDT, 1 hour 18 minutes before
Area Forecast Discussion

730 PM CDT Thu Aug 31 2017

.UPDATE...
FOR 00Z AVIATION DISCUSSION.

&&

.SHORT TERM...
(Tonight-Sat Night)

Usually do not do it this way, but issued the afternoon suite of
forecast products before this late afternoon AFD composition to
give the variety of customers we serve at least the latest
detailed information within the AFM and PFM products. A lot
of time, effort, detail was put into the grids to ensure the
best and most accurate forecast possible for all those we serve.

Broke out a late this afternoon zone grouping per the latest
regional radar mosiac trends and short range model consensus,
including the latest HRRR solution.

Factored in the latest consensus short range model outlooks into
into this evening forecast period also. In addition to this, in
agreement with latest afternoon WPC Diagnostic Discussion
reasoning and applied it to the mid state region. As stated within
this discussion, model solution consensus seems to be slower than
the actual TD track. However, leaned toward a tri consensus
solution of the 31/12Z GFS, 31/12Z NAM, and the 30/00Z UKMET
across our area. These solutions seem to initialize best and
make reasonable sense with TD Harvey's track progression.
Looks like bulk of the heavier rainfall that the mid state will
experience will be between 01/00Z-01/09Z, bringing definite mdt
to heavy shwrs and the potential of sct tstms to mid state region.

With all this said, TD should continue to make its northeastward
progression and move into wrn portions of the mid state region by
01/12Z. It should be in the Nashville Metro area by 01/18Z, and
then continues its push northeastward into south cntrl KY by
02/00Z. To the east of its track, will continue to mention the
possiblity of iso/sct shwrs/tstms. As is the case with a
tropical system like this, on the east side within the spiral
rain bands that are presently moving across the mid state region
the potential exists thru at least the early evening tonight of
iso tornadoes forming. As the sfc low moves northeastward, any
chance of iso/sct tstms should end, with moderate rainfall
continuing. So, rainfall will be experienced across the mid state
thru Friday night.

As what by then will be after 02/00Z the remnants of TD Harvey
continue to push northeastward, will go with light iso to sct
light shwrs across cntrl and eastern portions of the mid state on
Sat. Rainfall chances should end across the mid state by Sat
night.
