KEY MESSAGES

Issued at 1151 PM CDT Sat Aug 15 2026

- Near triple digit temperatures will continue through at least early next week, posing an increased threat for heat-related illness.

- Elevated fire weather conditions will continue to pose a risk for quick fire starts and rapid fire spreads. - Those spending time outdoors over the next week should follow all heat-related and fire weather precautions and safety tips (refer to weather.gov/shv for more details).

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.
