Area Forecast Discussion
National Weather Service Lake Charles LA
533 PM CST Thu Nov 30 2023
...New AVIATION...
.SHORT TERM...
(Tonight through Saturday night)
Issued at 345 PM CST Thu Nov 30 2023
Mid-afternoon sfc analysis shows a warm front lifting slowly nwd
across the cstl zones while a sfc low is noted over the TX
Panhandle...otherwise high pressure centered over the sern CONUS
continues providing a moist serly low-level flow across the
region. Water vapor imagery shows troffing over the wrn CONUS with
a cutoff low/significant shortwave moving out of the Rockies.
The combination of all these features has led to the development
of widespread rainfall across the vast majority of the forecast
area/adjacent coastal waters, although stronger convection has
been limited by a dry layer aloft and a definite lack of
instability/CAPE per 18z KLCH sounding. That being said, some
embedded heavier convection has managed to develop behind the
warm front, primarily over the coastal waters where
instability/CAPE has been more readily available.
In the near term, the Wind Advisory already in effect has been
extended for the ern zones past the original midnight expiration
time based on latest guidance showing criteria force gusts
continuing...the new expiration time for these areas is 09z/03CST.
In addition, a Dense Fog Advisory has been issued for Jefferson
County (south and east of I-10) and Cameron Parish (all) as well
as areas generally surrounding Sabine and Calcasieu Lakes in
Orange County and Calcasieu Parish due to an encroaching marine
fog as mid 60s dewpoints over upper 50s/around 60 SSTs continues
to get pushed inland on the stiff serly/srly winds. Skycams from
around the Golden Triangle and Lake Areas have already shown this
fog pushing well inland today and this problem will likely get
worse tonight as inland temps cool.
Otherwise not many changes to the inherited grids/zones this
afternoon. Rain/heavier showers/storms will continue through this
evening before departing the forecast area from west to east late
this evening through the overnight hours as the attendant
shortwave pulls away from the region. High res guidance indicates
that as we move through the evening, higher CAPE air is progged to
surge nwd with the frontal boundary, which could open the door to
a round of severe weather primarily this evening and into the
overnight as forecast soundings continue to show abundant low-
level shear. Therefore, much of the forecast area remains in a
slight risk for severe weather (primarily tornadoes and damaging
wind gusts) through tonight per SPC. Similarly, the risk for
excessive rainfall should expand nwd as the stronger
convection/heavier rains spread more inland later..and thus a
slight risk for flash flooding rains remains in place per WPC.
The low over the TX Panhandle will gradually pull a weak cool
front into the area tomorrow, with initially just some lingering
showers/few storms expected over our far sern zones. However the
boundary is progged to slow and as another disturbance rounds the
wrn CONUS trof and pushes into the region, accompanied by a good
slug of Gulf moisture, another round of showers/storms is expected
to spread across the forecast area from the Gulf. This activity
will gradually start moving out of the area by late Saturday
night.

.LONG TERM...
(Sunday through next Wednesday)
Issued at 345 PM CST Thu Nov 30 2023
The long wave trough axis will be roughly over the region at the end
of the weekend with moisture streaming northeast across Southeast LA
into the SE states. A cold front will also be departing the forecast
area early Sunday with a drier air mass filtering in, however a few
light showers may still be possible across the coastal waters and
into lower Acadiana which may still be under the stream of Pacific
moisture to start the day.
Early next week, a surface ridge will shift east across the gulf
coast with pleasant, near normal to slightly warmer than normal
conditions stretching into mid week. The onshore flow will resume
by late Monday as the ridge center exits east and another front
approaches.
Late Tuesday into Wednesday low pressure will move across the Ohio
Valley with a short wave. This will swing a cold front through the
local area, however no precip is expected at this time. High
pressure will dip south through the plains decreasing temperatures
for the second half of the week to slightly below normal.

.AVIATION...
(00Z TAFS)
Issued at 521 PM CST Thu Nov 30 2023
Widespread showers are ongoing across the region along with strong
southeast winds and low cloud ceilings. This is all occurring
ahead of a low pressure center swinging across the region. A
period of thunderstorms is expected from about 00 to 03Z when
better wind shear starts to work into the region.
Otherwise, on and off showers and all other impactful conditions
(winds and low ceilings) will prevail through at least midnight
tonight. At this point, the low starts moving to the north and the
pressure gradient can relax. Winds will diminish after 06Z which
should allow ceilings to fall further and for fog to develop.
Especially at LCH and BPT where a Dense Fog Advisory has been
issued through 15Z tomorrow morning.
The final hurrah of showers will be a line of heavy showers and
some thunderstorms that moves through from west to east after 06Z.
Timing of the end of SHRA will follow this line, ending at LFT and
ARA sometime around 12Z.
&&
.MARINE...
Issued at 345 PM CST Thu Nov 30 2023
The only changes to the inherited headlines on the coastal waters
this afternoon was the addition of the marine Dense Fog Advisory
late tonight for the near shore waters west of Intracoastal City
(although guidance shows dense fog potential mainly west of
Cameron) as well as Sabine and Calcasieu Lakes. Otherwise, the
Gale Warning continues through its expiration time of midnight
tonight with SCA conditions expected thereafter.
