Area Forecast Discussion
National Weather Service Lake Charles LA
1227 PM CDT Sun Aug 25 2019
.AVIATION...Rain and isolated to scattered thunderstorms will
continue through the afternoon which will create periods of MVFR
or IFR conditions. Convection is expected to decrease in coverage
around sunset, however showers can still be expected along the
I-10 corridor to the coast through the night. Winds will be
generally light however gusts of 15kts or more may accompany any
stronger shower or storm.

.PREV DISCUSSION... /issued 957 AM CDT Sun Aug 25 2019/
UPDATE...
Still having difficult time getting instability to make it inland,
however some breaks in the cloud cover across portions of the area
may help aid in increasing instability and produce locally heavy
rainfall this afternoon, but at this time it does not appear
widespread enough to continue the watch past the current
expiration time. CAM guidance does continue to indicate the
potential again tonight for a heavier band from portions of
Cameron Parish into lower Acadiana, watch was already extended for
this region and see no reason to deviate from that thinking at
this time.
Minor updates coming with current radar trends included.
PREV DISCUSSION... /issued 630 AM CDT Sun Aug 25 2019/
DISCUSSION...
For the 25/12Z TAF Issuance.
AVIATION...
A mid level low off the southwest Louisiana coast will move
northeast and work with tropical like moisture to produce numerous
showers and a few thunderstorms today. Looks like the majority of
the activity will be moving from off the coast into south central
Louisiana and affect KLFT/KARA by mid morning and continuing into
the afternoon. MVFR with brief IFR conditions expected in the
stronger showers and storms.

PREV DISCUSSION... /issued 412 AM CDT Sun Aug 25 2019/
DISCUSSION...
Short Term [Today and Monday]
A diffuse surface trough continues to persist along the coast of
the northwestern Gulf of Mexico this morning. This system
supported numerous showers and thunderstorms across the region
yesterday. While most areas saw less than an inch of rain, MRMS
derived precipitation totals indicate some parts of Cameron Parish
received over 5 inches of rainfall yesterday.
The atmosphere will continue to be supportive of efficient
rainfall production again today. The 00Z KLCH sounding sampled a
PWAT value of 2.64" and satellite derived PWAT values across much
of the northern Gulf Coast remain well above 2". Meanwhile, the
warm cloud layer continues to exceed 10 kft and the vertical wind
profile remains weak.
While all of southeast Texas and southwest Louisiana will have the
potential to see rainfall today, the most likely chance for
heavier rainfall will extend primary along and south of I-10 from
southwest Louisiana into lower Acadiana. These areas will have the
potential to receive 1-3" of rainfall with higher end amounts of 5
inches or more possible. The potential for heavy rainfall will
continue through late this afternoon into the overnight hours
across lower Acadiana as the surface trough begins to lift
northeastward. Some of the CAMs, in particular the NMM and NAM
Nest, were hinting at the potential for a narrow heavy rainband to
develop across Acadiana during the overnight hours. While not the
most likely scenario, this supported at least a threat for
flooding and the Flash Flood Watch was extended for Acadiana and
southeast Louisiana through Monday morning.
On Monday, a shortwave trough will move across the Mississippi
River Valley and into the Great Lakes. In the process, it will
"pick up" the weakness in the upper level height field that has
been located over the area the past several days. The decreasing
upper level support and exiting surface trough will result in less
widespread precipitation and warmer temperatures on Monday.
Long Term [Tuesday through Saturday]
Another shortwave is forecast to dig into the Central Plains
during the Tuesday to Wednesday timeframe. This should provide
enough support for a surface boundary to push southward to the
Gulf Coast along with some slightly drier air. As a result, a more
typical late August weather pattern is expected for the long term
period with chances for isolated to scattered showers and
thunderstorms each day, mainly from mid-morning through the late
afternoon hours. Temperatures will also return to normal values
with highs in the low to mid 90s and lows in the low to mid 70s.
MARINE...
A surface trough along the northwestern Gulf of Mexico will
continue to support scattered to numerous showers and
thunderstorms today and Monday. The trough will exit the region on
Tuesday which will result in daily precipitation chances over the
coastal waters trending closer to normal for late August by early
next week.

A very moist and unstable tropical airmass is in place across the area. Meanwhile...the vertical wind profile over the area is light and variable. These conditions are favorable for the development of tropical funnel clouds...especially where rain cooled boundaries...known as outflow boundaries...and the seabreeze collide. These tropical funnel clouds are usually short-lived and do not reach the ground. If the funnel cloud becomes more severe and reaches the ground...minor damage may occur...and a tornado warning will likely be issued.
