What forecasters said that day

The local office's own words before this small craft advisory 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 small craft advisory went out at Jan 30, 1:04 PM CST, 2 hours 32 minutes earlier.

Area forecast discussion, Jan 30, 1:04 PM CST, 2 hours 32 minutes before
Area Forecast Discussion
National Weather Service New Orleans LA
104 PM CST Sat Jan 30 2021

.UPDATE...

Updated for 18z aviation discussion.

&&

.AVIATION...

Mainly VFR conditions will prevail through the evening hours along
with southerly winds occasionally gusting 20 to 25 knots. Lowering
CIGS to MVFR range are expected along with some lowered visibility
at times as SHRA moves into the region. These lower MVFR
conditions are expected to start from west to east during the
03-06z period from KBTR to KMCB/KHDC/KHUM and 06-12z for
KMSY/KNEW/KASD/KGPT. A few hours of IFR are expected at several
airports mainly from early to mid morning. 22/TD

&&

.PREV DISCUSSION... /issued 443 AM CST Sat Jan 30 2021/

SHORT TERM...

High pressure will move east of the CWA today bringing an increase
in cloud cover with a primarily dry day for the daylight hours. A
much warmer day with highs approaching 70 as a brief return flow
ahead of the next system takes place. A vigorous surface low
along with a short wave trough will march eastward from the Texas
panhandle and into the middle Mississippi valley throughout the
day today. The trough will drag an associated frontal boundary
into the Arklatex area by this evening bringing a round of showers
into the area with the best chances of rain for most areas being
between midnight and sunrise on Sunday. Rainfall totals appear to
be mostly less than an inch as best instability and lift are not
present while the stronger dynamics remain well to our north.
Front will move through the region on Sunday around noon with
temperatures remaining relatively mild through the day on Sunday
as the full cold advection lags until Sunday evening. A gradual
decrease in clouds will occur on Sunday with breezy conditions
expected behind the front especially south of the lake. High
pressure will settle in Sunday night bringing dry and cold
conditions through Monday with highs only rebounding into the low
to mid 50s. Near freezing conditions will be possible on Monday
night/Tue morning as clear skies and calm winds will prevail
though that period.

LONG TERM (Tuesday through Friday)...
Deep longwave trough continues to shift east and out into the open
Atlantic Ocean. Strong surface ridge will be building in across the
entire mid section of the country. This will provide clear skies and
below average temps for the area, with highs and lows 5 to 10
degrees below normal on Tuesday. NBM guidance was a couple degrees
cooler than previous run, but seems to match well with MEX guidance
trend as well. The upper level pattern will be fairly progressive
next week, meaning expect temps to bounce back up to and above climo
quite quickly. Highs reach mid 60s Thursday and mid 70s on Friday.
Low temps on those days will show a more dramatic change from mid
30s to mid 50s in just a 24 hour run.

A series of shortwaves will then be moving through the Central
Plains Friday onward before the main trough tracks across the
country. The first wave will bring a weak boundary into the region
as well as accompanied showers. Its possible that the front may
stall in the CWA before the next shortwave pushes it through. New
guidance was slightly different than previous in terms of POPs.
Not surprised as models tend to struggle in the long range with
weaker systems. Either way, likely looking at shower activity
Friday through the weekend. MEFFER

AVIATION...
Seeing occasional visibility reductions to MVFR, but as clouds
encroach from the west, any radiation fog should diminish. Clouds
will gradually increase in coverage and lower in height with time as
the day progresses. MVFR ceilings look to become increasingly likely
after 18z as lower layers begin to saturate. IFR ceilings likely for
a few hours just in advance of the cold front, which looks to move
through the area between 06z-12z Sunday. Conditions should improve
to VFR behind the front prior to 18z Sunday. Forecast soundings show
thunderstorms shouldn't be much of a threat with the inversion near
800 mb. 35

MARINE...

High pressure will slide off to our east as a shortwave and
association front move through the eastern plains and then
eventually into the coastal waters tonight. Southerly winds will
increase ahead of the front today bringing exercise caution
conditions to the outer waters. Front pushes through
tonight...that along with a tightening gradient winds will
strengthen behind the front. Offshore flow will prevail through
the early part of the week with Small Craft Advisory conditions
likely for Sunday night into Monday for most if not all of the
coastal waters. Winds will decrease by Tuesday as high pressure
builds in overheard.
