Area Forecast Discussion
National Weather Service Lake Charles LA
323 PM CST Thu Dec 29 2022

...New SHORT TERM, LONG TERM, MARINE...

.SHORT TERM...
(Tonight through Saturday night)
Issued at 245 PM CST Thu Dec 29 2022

Low pressure is currently moving across the central plains while
the trailing cold front stretches into northern TX. A ridge is
just off the mid Atlantic coast. Aloft, moisture is streaming
north across TX into the upper MS Valley ahead of an upper
disturbance that is also moving into the plains. Locally, the
pressure gradient between the plains low and Atlantic ridge is
fairly tight producing gusty winds that are advecting in gulf
moisture which has dramatically increased over the past couple of
days. A modest coverage of showers and a few storms have been
streaming across SE TX today, but coverage is currently
increasing.

Tonight the coverage of convection will continue to increase as
the cold front and short wave draw closer. Modest instability and
shear, but ample moisture will provide the threat of an isolated
severe storm and marginal to slight flash flood potential. While
the ground is somewhat saturated due to rains a couple weeks ago,
enough drainage has occurred to lessen the flash flood risk.
Overall amounts are forecast to be between 1 and 3" area wide
through Friday with higher amounts possible. As always, localized
flooding may occur in urban areas where or if storms train.

Convection will gradually exit from west to east through Friday
with drier weather expected Saturday and for the New Year's Eve
festivities.

&&

.LONG TERM...
(Sunday through next Wednesday)
Issued at 245 PM CST Thu Dec 29 2022

The first day of the new year will start off quiet. Nearly zonal
flow aloft with a deepening pacific trough over the western CONUS.
Going into the end of the day, flow aloft will become southwesterly
as the trough and attached front moves eastward. At the surface, the
pressure gradient will tighten up leading to elevated and gusty
southerly flow. This will advect a plume of warm and moist air over
the region ahead of the front.

Forecast PWATS are in the 1.5-1.8 range which is clear above the
climo 90th percentile of 1.33 inches and closer to the daily max of
1.72 inches. Additionally, forecast soundings are showing some
elevated parameters for severe weather. Mainly CAPE and lapse rates.
Shear continues to look unimpressive, however better than model runs
yesterday. SPC has maintained the risk area over our northern
Parishes and extended it west over our northern Counties. In
addition to this, WPC has outlined all save lower Acadiana / the
Atchafalaya Basin in a slight risk for excessive rainfall. Flooding
appears to be the primary threat with QPF totals in the 2-3 inch
range Monday into Tuesday.

PoPs will linger post frontal passage however they will be isolated
with not as much moisture to work with. A weaker secondary cold
front is set to move through Wednesday into Thursday which will
clear out PoPs, bringing cooler and drier air.

Temperatures will be 10-15 degrees above climatological norms ahead
of the first front with highs in the low to mid 70s and lows in the
mid 50s to mid 60s. In addition to that, it will be quite humid with
dewpoints matching or falling a few degrees below air temps. The
front will help bring temps down near normal in the 60s for highs
and 40s for lows.

.AVIATION...
(18Z TAFS)
Issued at 1135 AM CST Thu Dec 29 2022

Gusty south winds along with patchy MVFR ceilings will continue
through the afternoon. While TS coverage has been fairly sparse,
coverage is expected to increase through the afternoon and
evening. Ceilings will also lower tonight and sea fog may move
into the coastal zones to near the I-10 corridor lowering vis.
Conditions will only gradually improve from west to east Friday,
but mainly after the TAF period.

&&

.MARINE...
Issued at 245 PM CST Thu Dec 29 2022

After an earlier report of sea fog near Cameron and satellite
imagery confirming fog along the coast east of Cameron into
Vermilion Bay, the coverage of fog has decreased. Imagery still
indicates fog near Pecan Island into Vermilion Bay, however, even
with a fair bit of mixing.

Winds are expected to decrease somewhat in the coastal waters
this evening and fog is expected to redevelop and/or spread. The
advisory was trimmed for the afternoon and evening, but left in
place for the nearshore waters plus the lakes and bays from 6Z
through 15Z.

Farther into the gulf waters where the cold water induced
inversion is not as strong, winds continue at 15-25kts. The SCA
will remain in place into Friday.

A boundary will move through the coastal waters tomorrow with an
offshore flow and lower dewpoints moving in. The moderate flow
will relax and sea fog will gradually dissipate.

The respite will be brief as another system will enter the region
early next week with a moderate to strong onshore flow and high
dewpoints once again affecting the coastal waters.

This Hazardous Weather Outlook is for central Louisiana, southwest
Louisiana, west central Louisiana and southeast Texas.

.DAY ONE...This afternoon and tonight.

Scattered showers and a few thunderstorms are expected tonight as a
band of convection moves through the area. There is a Marginal Risk
for severe weather, from this through tonight, across southeast Texas
into southwest Louisiana, west of an Alexandria to Pecan Island
line. The primary threats will be isolated damaging wind gusts and
isolated spin-up tornadoes.

There is also the potential for heavy rainfall overnight, with a
Slight Risk for excessive rainfall across southeast Texas into much
of central and southwest Louisiana that could lead to flooding of
urban and poor drainage areas.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

An ongoing band of showers and storms will be progressing east
across our Louisiana Parishes Friday morning. This band of storms
will be capable of producing strong to severe weather as well as
heavy rainfall. There is a Marginal Risk for severe weather for
portions of south central Louisiana, with isolated damaging wind
gusts and isolated weak spin-up tornadoes the main threats. There is
also a Slight Risk for excessive rainfall across central and south
central Louisiana that could lead to flooding of urban and poor
drainage areas.

The threat for severe weather and flooding should come to an end
Friday afternoon.

Another strong storm system will move into the area by Monday into
Tuesday. This system could bring the potential for severe weather as
well as heavy rainfall.
