Area Forecast Discussion
National Weather Service Lake Charles LA
1153 AM CST Thu Dec 7 2017

.DISCUSSION...
18Z TAFS

&&

.AVIATION...
Steady light to moderate showers will continue to traverse the
region beneath a mid layer stratus deck. VFR conditions will
prevail through the period with CIGs potentially lowering briefly
near convective bands.

Big question mark with this package remains the potential for the
rain to transition to snow during the early morning hours Friday.
Based on the latest guidance, continued to show rain mixed with
snow for the I-10 terminals beginning around 08Z, but this is only
a rough estimate. No accumulation is expected at any of the
terminals. Think that the precipitation will likely be out of AEX
before temperatures cool enough to support snow. As temperatures
warm following sunrise, any lingering precipitation (mainly for
LFT and ARA) will revert back to rain before clearing the area by
mid to late morning.

&&

.PREV DISCUSSION... /issued 1008 AM CST Thu Dec 7 2017/

DISCUSSION...
Update the grids through the night with the latest guidance.
Wintry precipitation chances have increased over the past 24 hours
and will be evaluating the latest guidance and make a
determination after coordination on any need to expand the winter
weather advisory.

PREV DISCUSSION... /issued 556 AM CST Thu Dec 7 2017/

DISCUSSION...
07/12Z TAF Issuance.

AVIATION...
Overrunning moisture is producing widespread VFR clouds based
around 6-8K FT. Patchy -DZ/-RA continues over the region and
expect off and on lt/modt RA to persist through the day as winds
remain southwesterly aloft in advance of a trough over wrn TX.
Northerly winds will be between 8-15 KT through tonight. Expect
rain to end at AEX during the evening while moisture will be slow
to clear the southern TAF sites through 12Z. Toward the end of the
period, a mix of -RA/-SN will be possible at these locations
as sfc temperatures approach the lower to middle 30s.

24

PREV DISCUSSION... /issued 535 AM CST Thu Dec 7 2017/

DISCUSSION...
Temperatures held in the the 40s overnight as clouds helped to
keep things a bit warmer. But there will be a  chance for some
ice pellets across central Louisiana and into the lakes region of
southeast Texas through the noon hour. Rains mostly light will
continue through the day and into the evening hours. A slight
chance for ice pellets return this evening and into the overnight
hours as temperatures drop. There will be a chance for black ice
on some of the area bridges in central Louisiana around
Alexandria and in the lakes region of Texas. Temperatures should
be a bit to warmer down along the I-10 corridor.

Observations in the coastal waters indicating sustain wind speeds
around 30 knots this morning. A gale warning for will continue in
the coastal waters today with seas ranging from 3 to 6 feet
nearshore and up to 11 to 12 feet 60 nautical miles from the
coast.

Another surge of colder air that extends from central Arkansas
down into north Texas will make it's way into the region
overnight. This will bring freezing temperatures into central
Louisiana and around the lakes region for southeast Texas towards
sunrise. As this latest system pushes down and into the coastal
waters... the upper level trof will finally push the precip off to
the south and east. Skies clearing late in the afternoon hours
Friday. Freezing temperatures to start out the morning hours
across central Louisiana into the lakes region in Texas over the
weekend. Temperatures down towards the coast will range from the
lower 30s to mid 30s for morning lows. This colder air mass will
remain in place into most of next week. Remember your pets and
plants.
