What forecasters said that day

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

NWS Lake Charles, LA wrote its last area forecast discussion before this freeze warning went out at Dec 7, 11:46 PM CST, 3 hours 15 minutes earlier.

Area forecast discussion, Dec 7, 11:46 PM CST, 3 hours 15 minutes before
Area Forecast Discussion
National Weather Service Lake Charles LA
1146 PM CST Thu Dec 7 2017

.AVIATION...

Light showers continue across SE Texas and SW Louisiana tonight
with light snow/sleet mixing in at times towards the Texas Lakes
Region. Low stratus is expected to produce prevailing MVFR
ceilings throughout the overnight hours. The main precipitation
type is expected to remain as rain for the next few hours before
colder air filters into the region. Snow/sleet should begin to mix
in more frequently at area TAF sites after 3 AM and thus have
TEMPO -SN in the TAFs through the morning hours. No accumulation
is expected at this time. Precipitation is expected to gradually
come to an end from northwest to southeast with ceilings improving
to VFR. Currently, precipitation is forecast to end at
KAEX/KBPT/KLCH by mid-to-late morning and KLFT/KARA by mid-to-late
afternoon. Northerly winds will gradually shift to northwesterly
throughout the day and decrease to 5-10 knots.

&&

.PREV DISCUSSION... /issued 945 PM CST Thu Dec 7 2017/

DISCUSSION...
Quite a challenging forecast this evening. Regional 88Ds continue
to show a large swath of mainly light precipitation extending from
cntl AL/srn MS through much of LA/ern TX down to the Rio Grande
Valley. Of most interest is a band of sometimes moderate snow
extending from the TX Hill Country to Deep East TX just outside
the forecast area which has been making a steady ewd progression.
WPC discussions this evening have leaned toward the thinking that
mid-level drier air approaching from the west should bring this
precipitation to an end as we approach the midnight hour, although
this would lead to an assumption that some frozen precip could
begin impacting the far nwrn zones shortly. However observations
from KJAS still show temps near 40...although evaporative cooling
has allowed the temp to drop several degrees in past 30 minutes.
With temps expected to stay above freezing, not expecting any
accumulation which would deem any advisories unnecessary...will
continue to monitor. However the nearby precipitation did require
I at least raise the POPs across the nwrn zones for now.

Farther southeast...some reports of occasional sleet are being
received from the Acadiana region via the media. This area is
already under the Winter Weather Advisory, even if it's not
scheduled to begin til 06z. Toyed with the idea of extending the
advisory to the coast around Vermilion/Atchafalaya Bays per WPC
probabilistic guidance, but with temps expected to stay above
freezing and the most likely p-type not being of the frozen
variety (thus no accumulation), elected to maintain the advisory
as is.

Elsewhere, just minor tweaks at most.

Update out shortly.

PREV DISCUSSION... /issued 552 PM CST Thu Dec 7 2017/

AVIATION...

No major changes were made from the previous TAF package. Light to
occasionally moderate showers will continue through the overnight
hours. The stratus ceiling should be prevailing from 3-5 kft with
TEMPO MVFR ceilings near the steadier bands of showers. After
midnight, there will be the potential for some snow or sleet to
mix in with the rain at KARA/KLCH/KLFT. No accumulation is
expected at any of the terminals at this time. Showers should come
to an end at KAEX/KBPT by mid morning and KLCH/KLFT/KARA by mid
to late afternoon Friday. Winds will remain northerly overnight
and gradually shift to northwesterly during the day Friday.

PREV DISCUSSION... /issued 316 PM CST Thu Dec 7 2017/

DISCUSSION...
This afternoon light rain and drizzle continues across much of the
area with temperatures from the lower 40s in the rain to to lower
50s outside the rainfall. A secondary front is located just to the
north of the region and will move south rather quickly this
evening and overnight.

The main concerns with this forecast is the potential for winter
weather overnight into Friday morning. Overall the past 24 hours
the probabilities for wintry weather have increased especially
east of a Lake Charles to Marksville line. Most guidance has rain
mixing with or changing to snow from north to south overnight. As
far as accumulations the best guess with the deterministic
forecast is for possible accumulations of less than 1 inch where
temperatures will be near freezing or snowfall rates will
compensate for warmer temperatures. This appears to be most likely
along and north of I-10 from Jefferson Davis and Allen Parishes
east. The worst case scenario for this event could shift things
a little more to the west and south with as much as two inches
possible and later shifts will continue to monitor the trends for
any possible advisory expansion.

Another concern is temperatures going below freezing across
northern portions of the area. Any water on area bridges may have
a chance to freeze across east Texas and West central Louisiana
despite precipitation coming to an end.

Temperatures will warm to above freezing across all areas by late
morning Friday and precipitation will be coming to an end as well.

Otherwise dry weather is forecast beyond tomorrow. The only
concern after tomorrow is the potential for Hard freeze conditions
in central Louisiana.
