KEY MESSAGES

Issued at 1024 PM CST Fri Dec 12 2025

- Areas of dense fog will give way to mostly cloudy skies today and some small rain chances across our southern counties/parishes in advance of much colder, frigid air.

- That colder, frigid air arrives late Saturday Night and through the day Sunday with wind chill temperatures during the day Sunday near freezing in some locations.

- The coldest air will settle into our region Sunday Night with a hard freeze likely across at least the northeast and/or eastern third of our region with several consecutive hours of below freezing temperatures through late morning Monday.

DISCUSSION

Issued at 1024 PM CST Fri Dec 12 2025

Dense fog has formed across portions of NE TX, N LA and SC AR in response to weak warm air advection in advance of a prefrontal sfc trough that should begin moving into our northern zones near or shortly before sunrise Sat Morning. This boundary may help to scour out the fog from the northeast as weak isentropic forcing near and especially south of the I-20 Corridor of NE TX and N LA may allow for some isolated showers as we move closer to sunrise. Seeing 2-3kft ceilings across this area currently and that may tend to keep the fog rather patchy in nature but can't rule out areas of dense fog that we currently have across these areas and that potential continuing through at least the mid morning hours on Saturday. For that reason, have issued a Dense Fog Advisory through 9 am Saturday near and south of a line from El Dorado to Shreveport to Tyler, Texas.

Isentropic forcing will only increase across our southern half as we go through the day Saturday and especially Saturday Night resulting in scattered to numerous showers with the greatest coverage likely across our southern and southeastern zones. Cannot rule out a clap of thunder across our far southern zones late today through tonight but not expecting any strong to severe thunderstorms with this activity in advance of the big cool down that will begin impacting our northern zones late Sat Afternoon with more widespread impacts as we go through Saturday Night. Temperatures will fall quickly Saturday Night with near freezing temperatures across our northern most zones. This colder airmass will continue funneling into our region during the day Sunday with high temperatures ranging in the middle 30s across portions of Southern Arkansas to the lower 50s across Deep East Texas. Combine those daytime temperatures with strong north northeast winds and wind chills may remain near to below freezing through much of the day Sunday across SC AR and NE LA. Winds will become light Sunday Night as the sfc ridge moves ovhd and that is when temperatures will really drop with lows ranging from the middle to upper teens across our northeast and eastern third with widespread 20s across the remainder of our region, by far the coldest air of the winter season.

The cold air will not last long as our region will only be skirted by this airmass. South winds return as early as Monday across our western most zones but good southerly return by Tuesday will allow for afternoon temperatures to rebound into the middle 50s to lower 60s areawide. The NBM held only slight chance pops across our northeast and eastern zones Wed into Thu and a weak upper trough across our region could possibly provide enough forcing to support this kind of precipitation but near zonal flow will set up towards the end of the forecast period and into next weekend. The warmup will continue as well with high temperatures in the 70s likely across our entire region as early as Thursday through the upcoming weekend.

AVIATION

(12Z TAFS) Issued at 532 AM CST Sat Dec 13 2025

For the 13/12z TAF update...Widespread sub-VFR conditions prevail for all terminals early this morning due to patchy to areas of fog across much of the region. While most terminals are seeing MVFR CIGs and visibility, there are some IFR to LIFR conditions filtering in at times. Expecting this trend to continue through the rest of the morning, with visibility improving after 13/15z and CIGs improving through the day for most terminals. Light showers will begin to move into portions of the area by late this afternoon and into the evening, but confidence is not high enough to include them at this time. More likely to happen is a shift to northerly winds towards the end of the period as a cold front moves through the region. In addition, winds will be gusty, with gusts of 20 kts or greater possible. /33/
