What forecasters said that day

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

NWS New Orleans, LA wrote its last area forecast discussion before this flash flood watch went out at Sep 13, 12:22 PM CDT, 2 hours 23 minutes earlier.

Area forecast discussion, Sep 13, 12:22 PM CDT, 2 hours 23 minutes before
Area Forecast Discussion
National Weather Service New Orleans LA
1222 PM CDT Mon Sep 13 2021

.UPDATE...
Updated for the 18Z aviation discussion.

&&

.AVIATION...
18Z TAF Package...
MVFR conditions prevail at most area airports due to lower
ceilings. TEMPO groups are highlighted for some area airports
this afternoon, mainly HDC, HUM, and BTR, for thunderstorms,
which will cause lower ceilings and visibilities. Vicinity showers
and thunderstorms will be possible at all other area airports
this afternoon. VFR conditions will return briefly overnight for
most area airports. Conditions will deteriorate to MVFR and IFR
conditions tomorrow in the early morning due to some fog
conditions and in afternoon due to showers and storms across the
area. These MVFR and brief IFR conditions will persist through the
end of the forecast period. MSW

&&

.PREV DISCUSSION... /issued 349 AM CDT Mon Sep 13 2021/

SHORT TERM (Today through Wednesday) AAAAAnd the moisture is back.
PW values will be at or above 2.0 for the next several days which
means any sh/ts will be able to produce heavy rainfall. Activity
will be moving at a good pace for the next few days which will help
keep rainfall totals for any individual storm within tolerance. A
flood watch could be contemplated if the system gets within or close
enough to keep any of its rain bands over the area for longer
periods. At this time there will be no new watches or advisories
posted. With a farther west forecast than some of the models were
hinting at yesterday, it will keep tide levels higher than normal
west of the river but should stay within 1 to 1.5 feet above normal
levels and this would not prompt a coastal flood advisory either.
All this being said, any forecast that shifts this system east, will
bring these numbers higher and would produce headlines. The bright
side of things for our neighbors, family and friends to the west is
that this system will have a hard time strenghtening as a portion of
the inner core is interacting with land and on its fcasted path,
this would continue to be the case. It is also interacting with an
upper trough to its west and NW imparting some SW shear over the
system.

Long Term (Wednesday night and beyond)...

Much uncertainty in the extended portion of the forecast regarding
the eventual disposition of Tropical Storm Nicholas. Current NHC
forecast (10 PM CDT Sunday) has it as a depression near the Texas-
Louisiana border Wednesday evening, and between Alexandria and
Monroe Thursday evening as it weakens or dissipates. Current
operational medium range models don't really indicate any deep layer
drying (1000-500 mb RH) through next weekend, It should be noted
that GFSBufr soundings from the 18z run do try to lower precipitable
water values over southwest Mississippi well below 2 inches for next
weekend. Across the remainder of the area, values remain above 2
inches. This will certainly present at least some threat of heavy
rain near wherever the center of the remnants end up for at least
Wednesday night into Thursday night. As the forecast scenario
becomes a little better defined, there may be shifts in forecast
rain amounts, both in magnitude and location.

With no rapid changes indicated by the models in the extended
period, there's little day to day change in PoP values or
temperatures noted in the NBM guidance. NBM PoPs somewhat more
resemble the GFS medium range PoPs (ECMWF looks a little dry). No
significant adjustments made to NBM PoPs or temperatures. Later
shifts may need to bump up the wind fields a bit though. 35

MARINE...

SE winds with speeds around 15kt should continue. Any thunderstorms
will be capable of bringing rapidly higher winds and seas. As
Nicholas moves north, a swell train will continue to cause the
overall seas to remain in advisory status west of the river through
Tuesday. After Nicholas weakens, seas will fall back to a wind
driven sea but SE winds of 10-15kt will remain into Wed and shift to
S and finally SW Wed through Thu.
