.DISCUSSION...
Issued at 1151 PM CDT Sat Aug 15 2026

Upper-level ridge centered across the region to maintain near
triple digit temperatures areawide. A surface high across the
northern gulf will continue to provide a southerly fetch of gulf
moisture across the ArkLaTex maintaining afternoon heat index
values from 105 to 110 degrees through at least Tuesday. Thus, the
Heat Advisory that is currently in effect through Monday will be
extended into Tuesday.

An areawide Heat Advisory may not be necessary on Wednesday as the
upper-level ridge responsible for the heat builds westward. An
upper-trough is forecast to swing southeast into the mid-
Mississippi Valley bringing increased instability and mixing to
limit afternoon highs across Arkansas and north Louisiana to the
mid to upper 90s from Wednesday onward. However, portions of east
and northeast Texas as well as southeast Oklahoma will remain on
the eastern periphery of the ridge with near triple digit highs
continuing through Friday, likely prompting continued Heat
Advisories across these areas.

Otherwise, with instability increasing across portions of south
Arkansas and north Louisiana, a few showers and thunderstorms may
be possible on Thursday and Friday afternoons. /05/

.AVIATION...
(12Z TAFS)
Issued at 546 AM CDT Sun Aug 16 2026

Latest IR Imagery showing some low MVFR cloud cover trying to form
in the vicinity of the LFK terminal but not seeing near as much
cloud cover as we have been seeing the last couple morning
approach our NE TX terminals. Only added TEMPO MVFR to the LFK
terminal as a result for a few hours this morning. Otherwise, we
should see a growing cu field across our airspace with the aid of
daytime heating. That cu field will dissipate this evening with
VFR conditions prevailing through the next 24 hours.

.FIRE WEATHER...
Issued at 546 AM CDT Sun Aug 16 2026

Combination of dry fuels, low afternoon relative humidity and S to
SW winds sustained near 10kts with some higher gusts possible
across mainly NE TX will result in an elevated wildfire threat
today across all districts in SE OK, SW AR, NE TX and N LA. Those
conditions will begin materializing by late morning with
conditions beginning to improve after sunset with RH beginning to
rise and wind speeds diminishing.
