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

(00Z TAFS) Issued at 618 PM CDT Sat Aug 15 2026

For the 16/00z TAF update...No changes needed to be made for this TAF period. VFR conditions will continue to prevail for all terminals throughout. Left some mention of BR for KLFK towards morning, but not expecting them to fall below VFR. Otherwise, still seeing a few stronger gusts out there this evening, but we will gradually calm for all areas during the overnight hours and remain under 10 kts through the remainder of the period. /33/

FIRE WEATHER

Issued at 1140 AM CDT Sat Aug 15 2026

Fire weather conditions will remain favorable for fire starts and fire spreads into next week given the continued hot and dry conditions. Min RH values will dip to between 30 and 40 percent this afternoon with SW winds generally around 10kts. Sunday will feature lower afternoon RH values area-wide, but especially across East TX where more aggressive mixing is expected to lower dewpoints into the 60s (closer to 70 or in the lower 70s elsewhere). This could result in min RH values near 20 percent, with the remainder of the area continuing to dip into the 30 percent range. Winds will still remain out of the SW around 10kts.
