KEY MESSAGES

Issued at 338 PM CDT Sat Sep 12 2026

- Remnant sfc trough will linger over the region today along the eastern periphery of the ridge axis. This will serve as a trigger for isolated convection through the early evening hours.

- Heat headlines have returned and will remain across the Four- State Region, as upper ridging expands back across the area through the weekend.

- Intense heat will persist throughout much of next week as upper ridging settles over the region. More heat headlines are possible along with increased wildfire concerns. However, we could see a pattern shift by the end of week.

DISCUSSION

Issued at 338 PM CDT Sat Sep 12 2026

Upper ridging has started to build back into the area today, which has yielded dry conditions so far. However, a remnant sfc trough lingers along the northern and eastern periphery of the building ridge axis. This has served as a trigger for some isolated convection north and east of our forecast zones. Some of this convection may hold together and move into portions of the area as it continues to slowly push southward this afternoon into the early evening hours. Also, there could be enough weakness under the ridge for some isolated convection to develop across the region during peak heating. So, decided to add slight chances POPS areawide through the early evening hours, when most of the convection should diminish. There is a Marginal Risk for severe weather across our SE Oklahoma and Southwest Arkansas zones with this convection. Damaging winds are the primary threat, along with some small hail. Expect another quiet, mild, and humid night, with lows in the low to mid 70s. Because of the building ridge, a Heat Advisory was issued for the entire Four-State Region today. That advisory has been expanded through Sunday evening, as the ridge continues to gain a footing in the area. High's on Sunday, will climb back into the mid to upper 90s, with a few isolated triple digit readings possible.

Upper ridging will become anchored across the region for a good portion of next week. This should bring us much drier conditions, although a stray isolated shower and thunderstorm can't be ruled out during peak heating. The drier conditions will likely keep heat headlines across the region and cause some elevated fire weather concerns. By the end of next week, long-term models suggest we could see a pattern change, with the ridge sliding west of the area. At the same time, the models also introduce some activity in the northern Gulf. At the very least, this could bring us some cooler conditions and much needed rainfall. /20/

AVIATION

(00Z TAFS) Issued at 645 PM CDT Sat Sep 12 2026

For the 13/00Z TAF update, a round of VCTS/-TSRA continues to proceed southward across the airspace, producing some isolated chances of MVFR vis/cigs through 13/02Z before diminishing with the loss of daytime heating. Surface winds will slacken to VRB through 13/15Z before returning from a southerly direction through the end of the period. Another round of VCTS convection is expected to redevelop across the entire airspace after 13/20Z through the end of the period. /16/

SPOTTER INFORMATION STATEMENT

Issued at 338 PM CDT Sat Sep 12 2026

Spotter activation is not expected, but a few strong to severe storms cannot be ruled out across parts of Southeast Oklahoma and Southwest Arkansas through the early evening hours. /20/
