DISCUSSION

Issued at 1009 AM CST Sat Dec 13 2025

Weak frontal boundary across the I-20 corridor to linger through today. Low-level moisture south of the boundary which has contributed to morning fog will eventually translate into increased showers and isolated thunderstorms later this evening in advance of a stronger cold front that will dive south across the region. The best chances for rainfall will be across mainly Deep East Texas and North Louisiana. Could see post-frontal elevated showers late this evening as the shallow arctic air begins to deepen areawide. By daybreak, temperatures across southeast Oklahoma and south Arkansas are forecast to have fallen into the upper 20s to lower 30s. Any lingering precipitation is forecast to to be be driven south with the front.

Cold air advection to continue into Sunday with afternoon high temperatures forecast to range from the mid 30s into the 40s. However, an increased pressure gradient will allow for wind speeds around 10 to 15 mph with higher gusts. The higher winds will allow for wind chill values to from the upper 20s across south Arkansas and north-central Louisiana to the lower 40s across east and northeast Texas. On the bright side, wind speeds are forecast to become near calm on Sunday night across most areas mitigating wind chill impacts. However, overall ambient temperatures are forecast to fall into the upper teens to lower 20s across most of the ArkLaTex. From 10 to 15 hours of below freezing temperatures can be expected across the region.

In terms of advisories or warnings, the only area of concern would be across portions of northeast Louisiana as wind speed values of 5 to 10 mph may persist into Sunday night as temperatures fall into the low to mid 20s. Resulting wind chill values of 15 degrees across a few counties remain marginal for a Cold Weather Advisory. Will monitor trends over the next couple of forecast packages to determine if an advisory will be needed.

The arctic airmass to exit the region to the east on Monday allowing for a gradual warming trend as southerly flow returns. However, another round of subfreezing temperatures in the upper 20s across north Louisiana is expected on Monday night with departing surface high.

Otherwise, scattered rain chances from Tuesday night into Thursday as a broad weak upper-trough swings east across the region. Zonal flow behind the trough will maintain a semi-unstable airmass with partly cloudy skies prevailing. Expect mild temperatures with highs in the 60s and lows in the lower 50s. /05/

AVIATION

(18Z TAFS) Issued at 1137 AM CST Sat Dec 13 2025

IFR/LIFR cigs will continue through mid-afternoon across the region before slowly improving to MVFR, along and N of a warm front that has begun to lift N into Lower E TX and N LA S of I-20. In fact, areas of FG will likely persist through mid- afternoon as well along the I-20 corridor as well just N of the front, primarily affecting the SHV/MLU terminals, before the bndry stalls later in the day in VC of I-20. Isolated -SHRA will be possible this afternoon along and just N of the front, and could affect MLU, but should do little to affect cigs/vsbys other than what is currently being observed. An arctic cold front will begin to shift S into the region by/after 00Z Sunday, which will maintain low MVFR cigs this evening through at least a portion of the overnight hours before exiting the region shortly after 06Z. Widely scattered -SHRA should develop in VC of the front especially across portions of E TX/N LA, and thus have inserted VCSH mention for all but the TYR and SW AR terminals this evening. Cigs should gradually improve with the passage of the front as the colder/drier air begins to deepen, with cigs beginning to scatter out/clear from NE to SW by mid to late morning Sunday. VFR conditions will return to Deep E TX/Cntrl LA shortly after the end of the 18Z TAF period. Vrb winds 5kts or less this afternoon will become NNE 10-17kts with gusts to 25kts following the fropa later this evening. /15/
