What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Oct 5, 1:55 PM CDT, 5 hours 16 minutes earlier.

Area forecast discussion, Oct 5, 1:55 PM CDT, 5 hours 16 minutes before

Area Forecast Discussion
National Weather Service Nashville TN
155 PM CDT Tue Oct 5 2021

.DISCUSSION...

Upper low remains camped out over MS this afternoon. The favorable
moisture channel is setup along and east of the axis which extends
north of the low. The system will slowly move northward over the
next 24 to 36 hours. Impulse driven energy will continue to work
northward across our area this evening then again late tonight with
likely to categorical pops.

On Wednesday, some west to east curvature and shear will develop to
the east of the upper low. Energy will again pick up late in the day
with pops once again reaching the likely category. In fact
categorical pops are on order for a good portion of the Plateau for
Wednesday night.

As for precip amounts through Wednesday night, it looks like 1 inch
far northwest up to 2 inches far southeast/south central areas. This
is below ffg levels so will not be including any flood watches with
the forecast.

Pops will begin a down trend on Thursday as the low lifts northward
and the better channeling moves eastward. By late Thursday night
only a 20/30 percent chance will reside along the plateau.

Near term temps look to be above normal, especially overnight lows.

In the extended forecast, upper ridging to build in over the weekend
with warm and pop free conditions. A weakening frontal boundary will
be on approach early next week with low pops returning. Forcing
appears to be a little overdone with the models,gfs especially,
given the mslp model returns. Otherwise, temperatures looking warm
to the tune of 10-12 degrees or so above normal.

.AVIATION...
18Z TAF DISCUSSION.

BNA/MQY/CKV/CSV...Mainly light showers continue to spread into
Middle Tennessee as an inverted trough develops across the mid
state. At the same time, a low height center near the confluence
of MS/LA/AR is helping to pull additional moisture into Middle
Tennessee, so we can expect high rain chances today and tomorrow.
The HRRR brings mainly scattered cells across the mid state during
the next several hours. There may be some storms embedded in these
echoes, but the chance of storms is low enough that we'll mention
just showers in the TAF's for now.
