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 Morristown, TN wrote its last area forecast discussion before this river flood warning went out at Apr 23, 3:07 PM EDT, 3 hours 52 minutes earlier.

Area forecast discussion, Apr 23, 3:07 PM EDT, 3 hours 52 minutes before
Area Forecast Discussion
National Weather Service Morristown TN
307 PM EDT Sun Apr 23 2017

.SHORT TERM /Tonight and Monday/...
A widespread flooding areal flood event is underway across the
eastern Tennessee Valley and Southern Appalachian region this
afternoon. Abundant moisture is combining with a slow moving cold
front and strong upper-level storm system to generate several
rounds of light to moderate, steady precipitation. Over the last
24 to 36 hours, the region has seen 2 to 4 inches of rain, with a
few localized amounts of 5 to 6 inches. The hardest hit areas have
been along the Cumberland Plateau, the Cumberland Mountains of
Southwest Virginia, and much of Southeast Tennessee. However, all
areas are experiencing rampant flooding along creeks/streams, low
water crossings, poor drainage areas -- which has resulted in
numerous road closures. As a result, a Flood Warning is in effect
for the entire CWA until 6:30 PM. This will need to be reassessed
by the evening shift at that time.

Latest runs of the HRRR/RAP indicate this activity beginning to
wane across the southern areas between 21-00z as a dry slot moves
in. However, locations across the Northern Plateau,
Central/Northern Valleys and the NC/VA/TN mountains may see
several more hours of light to moderate rainfall. This could
result in an additional 1 to 2 inches in some spots where heavy
training occurs. Eventually, some tapering off will occur --
roughly from 03-09z west to east. However, this may be a slow
process, so have expanded the watch for eastern areas until 12z
Monday. Some significant flooding issues may occur in these areas,
so travel is discouraged unless necessary.

Clouds and light rain will linger into the morning hours --
especially over upper East Tennessee and Southwest Virginia. Any
flooding issues may linger as well -- so use caution on the
morning rush hour commute. Temperatures will be slow to climb
given the cloud cover, so highs in the low to mid 60s will be
common.

.LONG TERM /Monday Night through Sunday/...
A few lingering showers are expected to slowly exit the area on
Monday as a upper low tracks along the east coast. High pressure
will build in late Monday into Monday night for a quite weather
pattern for mid week. The high will dominate area weather through
Wednesday for dry conditions and warmer temperatures. Models
beginning to show better consistency with a cold front moving in
around Thursday...bringing our next chance of showers and
thunderstorms. Model consistency deteriorates after Thursday...but
models do indicate a weak boundary moving through the region
around the Friday time frame providing a chance for additional
convective activity. Then...current model runs build a ridge of
high pressure over the area for Saturday and the next system
beginning to approach the area on Sunday.
