.DISCUSSION...
Issued at 947 PM CST Wed Dec 17 2025

A Dense Fog Advisory is currently in effect for much of the Ark-
La-Tx overnight tonight through 9am Thursday morning. Relatively
cool soil temperatures and ample low-level moisture from
persistant southerly flow is leading to increasing confidence of
lower cloud development. Areas in the Ouachita Mountains and
Central LA have already been reporting lowering visibilites over
the past few hours and is expected to spread in coverage
overnight as winds begin to die down. Areas of dense fog may
linger into the mid morning hours, so use caution while driving
since fog patches can catch drivers by surprise.

As the fog clears Thursday morning, a cold front is expected to
move through the area and bring some light rain/drizzle to our
north and eastern zones Thursday afternoon and into the evening.
Previous forecasts have included thunder with these showers, but
recent model guidance has the few areas of instability that would
be necessary for thunderstorms setting up further east, making
thunderstorms much less likely for the Ark-La-Tx. The persistant
warm temperatures should get a brief knock back after the frontal
passage. Temperatures will drop into the 30s Thursday night, with
some northern zones flirting with freezing again, before climbing
back into the mid 50s to low 60s on Friday afternoon. After which,
the zonal flow and southerly winds at the surface will take back
over and allow for a gradual warming trend going into the weekend.

One element of interest in the long range forecast is a low-level
disturbance that has the potential of bringing some low rain
chances to portions of our south and east. There is plenty of
uncertainty in this part of the forecast due to the overall lack
of consistency and the fact that there is little upper-level
support should this forecast verify. However, it is worth
mentioning and monitoring for any impacts to holiday celebrations
and travel. As it stands now, this rain would linger in our
southeastern zones from Sunday morning until late Sunday
night/early Monday morning. This rain would bring temperatures in
these areas down a bit due to the increased cloud cover and
evaporative cooling, likely into the 50s or 60s. Other areas
would likely still see temperatures in the 60s or 70s.

Regardless, expect temperatures to be well above average through
this weekend and into next week. Long-range model estimates have
Christmas temperatures solidly in the 70s for the entire region
with no rain in sight. The benign upper-level pattern seems to
support the quiet Christmas forecast, but there is still plenty of
time for tweaks between now and then.

(06Z TAFS)
Issued at 1128 PM CST Wed Dec 17 2025

For the 18/06z TAF update...Sub-VFR conditions will remain the key
focus throughout this TAF period thanks to lower ceilings and
some BR across the area. Visibility has already dropped for some
terminals and this trend will continue throughout the night
tonight and into the early morning hours on Thursday. I did leave
mention of some VCSH for tomorrow afternoon as a cold front
traverses the area along with a dramatic wind shift back to the
north. We probably won`t see much improvement in flight conditions
till late in this TAF period. /33/
