Area Forecast Discussion
National Weather Service Lake Charles LA
1153 PM CST Mon Nov 28 2016

.DISCUSSION...
For 06z TAF issuance.

&&

.AVIATION...
Kind of a challenging forecast tonight with several different
aviation parameters to deal with. First off, fog chances
overnight. A few ob sites around the region have already seen
visibilities fall below 1SM and multiple short-range/high-res
models depict this trend continuing as winds further decouple...
mainly starting coast and moving inland while also starting west
and spreading east. Conditions are only expected to improve
gradually through the morning hours, although copious low-level
moisture will maintain low ceilings likely on through the
afternoon. The next issue looks to be rain chances late in the
period as the next impulse aloft and sfc cool front begin to move
into the area. For now earliest shot at rain looks to be KAEX, but
shower development is expected to spread swd/sewd into the evening
hours as the impulse progresses. Thunder chances look much better
to our north...later TAF issuances will better refine the storm
threat through the night/morning.

.PREV DISCUSSION... /issued 944 PM CST Mon Nov 28 2016/

UPDATE...Coastal flood advisory and wind advisory for lower
Acadiana has expired. Updated zone package has been sent out.
Additionally expanded fog development into interior southeast
Texas where skies have cleared and radiational fog development has
begun. Much of the remainder of the area will see advection fog
south of stalled ne-sw boundary located from just south of
Alexandria to Just north of Beaumont. Dense fog development will
be possible and will continue to monitor.

PREV DISCUSSION... /issued 740 PM CST Mon Nov 28 2016/

UPDATE...Radar now showing minimal convection over the area and
have reduced evening pops to slight chance. Vigorous shortwave
trof is now advancing north and northeast of the region with
sharply drier air overspreading the area in its wake. NE-SW
oriented surface boundary extends from just south of Alexandria to
just north of Beaumont. Radar showing a few showers holding on
along the front. Expecting limited further advancement of front
through the night and have introduced areas of fog along and south
of feature. Will allow lower Acadiana wind advisory and coastal
flood advisory to continue to expiration at 9 pm.

PREV DISCUSSION... /issued 550 PM CST Mon Nov 28 2016/

DISCUSSION...
For 00z TAF issuance.

AVIATION...
Local 88Ds show convection has mostly ended for the wrn 1/2 of the
area with just a few stray showers around KLCH. Activity is much
more likely in the neighborhood of ern TAF sites for at least the
next hour or so before pushing ewd with the vort max aloft.
Thereafter the primary issue appears to be fog potential as low
clouds clear, winds try to decouple and copious low-level moisture
lingers...for now have hit fog the hardest at the
climatologically-favored sites. Expect conditions to improve
tomorrow morning post-sunrise with VFR conditions expected most
of the day...will take a closer look at late afternoon convective
possibilities at 06z issuance.

PREV DISCUSSION... /issued 320 PM CST Mon Nov 28 2016/

DISCUSSION... Wx map shows the strong surface and upper level
storm system over most of the Central and Eastern U.S. with
strong gusty winds over our region this afternoon. The cold front
is just entering Tyler and Northern Jasper counties in SE Texas,
with limited convection so far here. Radar showing a little more
showers with limited thunderstorm activity across Louisiana.
Tornado watch 501 will continue until 5 PM CST for most of
Louisiana along and north of I-10 into Central Louisiana, and
Orange/Jasper/Newton counties in SE Texas. For the remainder of
the hazards, will make no changes at this time to earlier
updates. The wind advisory will expire at 3 pm over inland SE TX
as the frontal trough approaches, 6pm for SE TX/C and SW LA, and
over Acadiana at 9 pm. See marine discussion below for hazards.

Tides are near 3.0 to 3.5 feet MLLW this afternoon within the
double maximum high tide cycle. With the large wave run up today,
will leave the Coastal Flood Advisory through this afternoon and
early evening over SC LA.

For the forecast now, this first round of thunderstorms will end this
evening with minimal pops overnight as the front moves through and
energy aloft shifts northeast. Another shortwave trough will move
through Tuesday afternoon and evening with the front moving back
north and showers and thunderstorms increasing once again over the
region. The best chances of showers and thunderstorms will be over
Louisiana, as well as a slight chance of severe thunderstorms as
outlined by SPC Day 2 outlook. This will continue into early Wednesday,
ending after the stronger cold frontal passage to bring much
cooler and drier air to the region. Cooler than normal
temperatures expected for Wednesday night into the weekend.

The next system to affect the region will begin Friday, gradually
increasing showers with an isolated thunderstorm. This will be
more of an over-running event as most of the region will stay in
the cool sector, with a coastal trof or surface low developing for
Saturday. Shower chances looks to remain on and off through Monday
of next week.

DML

MARINE...
Gale Warning for the 20-60nm zone from Cameron westward expired at
3pm, with the remaining 20-60 nm zones to expire at 6 pm. SCA
will continue through this evening, slowly expiring from west to
east. Otherwise, front expected to stall over the coastal waters
tonight, to move back north as a warm front Tuesday. The stronger
cold front expected to move through Wednesday, yielding moderate
offshore flow through Thursday.
