KEY MESSAGES

Issued at 1140 PM CDT Fri Aug 14 2026

- Heat wave continues with our hottest temperatures this summer likely this weekend into early next week.

- Wildfire threat continues to increase with persistent drying. prevails. - An upper-trough swinging across the central US could split the upper-ridge bringing slightly cooler temperatures to the region by midweek.

DISCUSSION

Issued at 1138 PM CDT Fri Aug 14 2026

Heat ridge aloft to remain parked over the ArkLaTex through the the middle of next week driving afternoon high temperatures to near or slightly above 100 degrees each day. A surface high in the gulf will continue to maintain south to southwest flow across the region. However, wind speed values will be slightly lower on Saturday compared to the previous few days due to a more relaxed pressure gradient. In terms of heat index values, many of our observation sites observed dewpoint values mixing down into the 50s and 60s earlier today, limiting heat index values to a couple of degrees on either side of 105 degrees. However, with lower wind speeds forecast for Saturday, mixing may be more limited, preventing dewpoint values from falling much below 70 degrees. The ConsAll model seems to also agree with this line of reasoning and will thus be used for Saturdays dewpoint values in the official forecast, positioning heat index values more within the 105 to 110 degree window.

An upper-trough swinging into the central CONUS on Wednesday could bring changes to the weather pattern across the ArkLaTex late in the forecast period. Should the trough dig far enough south to split the upper-ridge, afternoon high temperatures will struggle to climb above the mid 90s across southwest Arkansas and southeast Oklahoma on Thursday and Friday. /05/

AVIATION

(12Z TAFS) Issued at 531 AM CDT Sat Aug 15 2026

So far, MVFR ceilings appear like they may just remain just west of our western most airspace this morning but will ride with TEMPO MVFR ceilings at the TYR and IFR TEMPO at our LFK terminals through 14-15z this morning just in case. Otherwise, VFR conditions will prevail through the next 24 hours. A weak cu field will develop with the aid of late morning and afternoon heating with that cu field dissipating during the evening. Not enough confidence to add low ceilings during the overnight hours tonight and predawn hours Saturday morning.

FIRE WEATHER

Issued at 531 AM CDT Sat Aug 15 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.

FIRE WEATHER

Issued at 141 PM CDT Fri Aug 14 2026

Increasingly hot and dry conditions will result in rapidly drying vegetation and fuels as soil moisture is further depleted in this building heat wave with more widespread triple-digit temperatures. Flash drought conditions already appear to be underway with spot fires popping up over the past week, and elevated fire danger will only escalate further in this currently stagnant weather pattern. Therefore, the threat of wildfire starts and potential for rapid growth will only increase through this weekend as temperatures climb higher and daily min RH drops lower into the 25-35 percent range. Winds will also shift more southwesterly, resulting in even drier air mixing down to the sfc during the hours of peak heating. A Fire Danger Statement is already in effect for Saturday and more likely to follow into next week.

SPOTTER INFORMATION STATEMENT

Issued at 1141 PM CDT Fri Aug 14 2026

Spotter activation is not expected at this time, but spotters are encouraged to report any wildfire activity to your local officials and fire department personnel.
