Issued at 947 PM CST Wed Dec 17 2025

- Mild to warm conditions will continue over the next week, with temperatures hitting the 70s before a cold front moves through Thursday afternoon.

- Friday will be cooler behind the front, followed by a return to the warming trend for the weekend and into next week, likely continuing through the approaching holidays.

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.

AVIATION

(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/
