...New UPDATE...

.UPDATE...

Wx map shows weak high pressure ridge extending from East
Texas/Louisiana northeastward, giving a weak pressure gradient
over the region. Winds are light and variable to calm inland, and
from the south around 5 kts across the coastal waters. Radar
showing a persistent shower around 15-20 miles south of Marsh
Island this evening, with no precipitation detected inland. With
the exception of the shower noted, satellite imagery showing
mostly clear skies across the remainder of the coastal waters and
inland areas. Patchy fog will be possible once again towards
daybreak Saturday for most of the area. Lows in the lower to mid
70s. Forecast on track with no updates needed at this time.

.SHORT TERM...
(Tonight through Sunday night)
Issued at 303 PM CDT Fri Sep 20 2024

Looking at the current pattern, an upper-level ridge extends
across the southern plains towards the northeast and is working
together with a high-pressure system that is located across the
Gulf Coast. This one-two combo will limit rain with rain chances
to near zero through the weekend with higher chances along the
coast. During this time the high pressure will keep our winds
light and variable.

Temperatures will be elevated each day this weekend, with high
temperatures in the 90s and low temperatures in the mid-70s. Dew
points will also be in the mid-70s. When combined with light and
variable winds, it will support the development of fog each
morning. A combination of the low winds and high dewpoints could
lead to widespread fog across Acadiana. While the NAM model shows
dense fog that would require a dense fog advisory, no other model
shows that happening so we will hold off on any advisories right
now.

.LONG TERM...
(Monday through next Thursday)
Issued at 303 PM CDT Fri Sep 20 2024

Long-term conditions will remain hot and dry, with daytime
temperatures several degrees above normal for this time of year.
The broad ridge will continue to dominate our weather pattern for
the first half of the week. Starting around midweek, a shortwave
trough will begin to move across the Midwest and will drive a cold
front south towards the coast. This front will be diffuse by the
time it reaches us, with the main impact being our winds shifting
to come from north. While the front will drop our temperatures and
dew points to more enjoyable levels, don`t expect fall-like
conditions yet.

Models are in large disagreement on the location
and strength of the front, especially in regards to precipitation,
so make sure to stay tuned to the forecast.

.AVIATION...
(00Z TAFS)
Issued at 627 PM CDT Fri Sep 20 2024

Afternoon clouds will continue to dissipate this evening, leaving
generally clear skies in place overnight. Outside of some patchy
fog developing late tonight, VFR conditions should prevail through
the period. Any vsby reductions to fog will likely only last a
few hours, with MVFR to IFR conditions possible. Light and
variable winds will trend more southeasterly by Saturday afternoon
with speeds less than 10 KT.

.MARINE...
Issued at 303 PM CDT Fri Sep 20 2024

High pressure offshore will continue the trend of hot, dry and
calm conditions. Seas are below 2 feet and will stay there
through the weekend. In addition winds will be light and variable.
The pattern will start to change around midweek as a front moves
offshore, increasing winds.

In the Gulf the NHC has a 50% region for development of a tropical
cyclone. There is little consistency between individual models or
model run-to-run consistency. It will be important to keep a
close eye on the forecast for the next several days.
