.KEY MESSAGES...

- Elevated rain chances continue through Sunday as a weak frontal
boundary interacts with deep tropical moisture.

- Storms will be capable of high rainfall rates that could lead to
nuisance street flooding.

- Below normal temperatures expected through much of next week as a
  series of weak frontal boundaries pushes through the region and
  reinforce a drier/cooler atmosphere.

.SHORT TERM...
(Today through Monday night)
Issued at 1210 AM CDT Sat Aug 30 2025

Outside of a few patches of drizzle, the radarscope is
clear early this morning as a quasistationary frontal boundary
continues to bisect the region roughly along the HWY 190 corridor.
The latest several hours of CAMS guidance have performed poorly in
showing significant convective redevelopment that has not yet
materialized. A few isolated showers could develop over the next few
hours, but the majority of activity doesn't seem likely to
initialize until late this morning through this afternoon. Calm
winds across the region may allow for some patchy early morning
fog development especially across areas that saw significant
rainfall yesterday. Parts of lower acadiana and southeast
Louisiana are already reporting fog at this hour. Any fog that
develops should dissipate by 14Z.

The frontal boundary and deep tropical moisture in place across the
region (2.19 PWAT on the 00Z KLCH sounding) will support another day
of widespread thunderstorm development with any of these capable
of high rainfall rates that could lead to nuisance street
flooding. The entire region remains in WPC's marginal risk for
excessive rainfall today through Monday. Convection should wane
through the evening similar to Friday although a couple of storms
could last into the late night.

The boundary and the deepest moisture will ooze to the coast by
Sunday keeping the highest PoPs confined to southeast Texas and
coastal portions of southwest and south central Louisiana with only
isolated storms possible as far north as Alexandria. Similar
conditions expected Monday as the boundary remains stalled near the
coast.

.LONG TERM...
(Tuesday through Saturday)
Issued at 1210 AM CDT Sat Aug 30 2025

Another, more progressive, shortwave will swing through
the area Tuesday pushing the stationary front further offshore and
advecting in a slightly drier airmass. This will largely bring
precipitation chances to an end by Wednesday. Another weak,
reinforcing boundary pushes through the region Thursday. Dewpoints
will fall into the mid to upper 60s Wednesday and Thursday allowing
overnight lows to fall into the mid to upper 60s for the first time
since June 1. Following the secondary frontal boundary Thursday, NBM
advertises lower 60s across central Louisiana and interior parts of
Southeast Texas which would be about 10 degrees below normal
should it verify (although nowhere close to records which are in
the mid 50s for the first week of September across cenla).

.AVIATION...
(06Z TAFS)
Issued at 1155 PM CDT Fri Aug 29 2025

Showers and storms have completely ended across the area however
we will see a redevelopment in activity over the next several
hours. While there could be dense fog near a few terminals, model
guidance seems to hint at no serious impacts at the terminals.
This will have to be watched through the night along with the
redevelopment of showers. A weak front still exists west to east
almost in line with the I-10 corridor. This will assist in seeing
more rounds of showers and storms for the southern terminals later
in the morning to afternoon hours on Saturday.

&&

.MARINE...
Issued at 1210 AM CDT Sat Aug 30 2025

Scattered showers and storms will redevelop across the
coastal waters today ahead of a meandering frontal boundary. This
front will slide toward the coast later in the day where it will
stall continuing to serve as a focus for storm development Sunday
through Monday. Winds will turn offshore from Saturday afternoon
through the middle of next week as the frontal boundary moves off
the coast and into the Gulf waters.

&&

.FIRE WEATHER...
Issued at 1210 AM CDT Sat Aug 30 2025

Showers and thunderstorms will develop again today
through Monday in response to a slowly advancing frontal boundary
bisecting the region. The boundary will push through the area
Saturday afternoon turning light winds out of the north through mid
next week pulling some slightly drier air into the region Tuesday
and Wednesday. A reinforcing frontal boundary will move through the
region Thursday maintaining the drier air through the end of the
week.
