.SHORT TERM...
(Today through Saturday night)
Issued at 328 AM CDT Thu Sep 19 2024

Patchy ground fog has developed once again this morning primarily
across central LA and interior SETX. May see some additional
development closer to the coast through the early morning, but
don`t expect significant visibility restrictions. Fog should
dissipate no later than 14Z.

Little change to the overall forecast philosophy through the
weekend as upper level ridging presently centered over southern
Texas will continue to dominate the weather pattern over the
western Gulf of Mexico. While a couple of isolated showers or
thunderstorms can`t be completely ruled out across the Atchafalaya
basin, consensus probs are below 20%. Temperatures will again
climb into the lower 90s with forecast heat indices at or just
above 100. Weak surface high pressure over the Southeastern U.S.
will keep the surface gradient very relaxed with light, variable
winds generally under 5 MPH. Near carbon copy conditions will
prevail through Saturday.

(Sunday through Thursday)
Issued at 328 AM CDT Thu Sep 19 2024

Late in the weekend a ridge will be situated across southern Texas
and Louisiana while a short wave pushes into the central plains.
Summertime temperatures can be expected while chances of rain remain
near zero.

Early to mid week, the ridge will drift east across the northern
gulf coast as the aforementioned short wave moves into central
sections of the country. As the ridge departs the local area, a very
modest increase in rain chances may occur. Temperatures will remain
near to slightly above climo norms.

.AVIATION...
(18Z TAFS)
Issued at 1201 PM CDT Thu Sep 19 2024

High pressure centered overtop the Texas/Louisiana state line is
in control of the forecast for the period, with only fair-weather
cumulus with MVFR ceilings and light, variable winds ongoing.

A few gusts may develop this afternoon with daytime mixing, but
due to high pressure, gusts will be variable/turbulent in nature.
After sundown, the same trend as in previous days can be expected:
improving skies after 01Z and patchy fog (4 to 5 SM) at most or
all terminals from 09 to 14Z.

After 14Z, any lingering fog will dissipate and mild, variable
conditions expected once again.

High pressure will continue building into the region today. This
ridge will bring about a prolonged period of warm, dry conditions
with light winds and low seas.
