KEY MESSAGES

Issued at 1227 PM CDT Wed Jul 29 2026

- A Heat Advisory remains in effect through 8 PM Thursday night as heat indices will climb each afternoon from 105 to 109 degrees areawide.

- Isolated to Scattered showers and thunderstorms have returned today and will continue into Thursday afternoon, with highest chances along and East of I-49, as a backdoor front edges into the Four State Region. - Seasonable temps and rain chances return once again this weekend, with the highest precipitation probabilities along and south of I-20.

DISCUSSION

Issued at 1227 PM CDT Wed Jul 29 2026

Afternoon mesoanalysis reveals the Four State region under the continued influence of the upper level ridge centered over the NM/TX border. This ridge will bring once again the persistant hot and mostly dry conditions that we've seen over the past two weeks. Temperatures areawide will rise once again into the upper 90s, which combined with the continuous South-Southwestern winds that bring moist air from the Gulf will see us reach heat indices up to 110 across the Ark-La-Tex. As a result, the areawide Heat Advisory that has been in place has once again been extended, now through 8 PM Thursday Night. Continue to practice good heat safety, hydrate often, limit outdoor exposure, have access to air conditioning, and check on heat sensitive neighbors.

An approaching backdoor frontal boundary will bring isolated to scattered showers and thunderstorms, mainly limited to the zones in Oklahoma, Arkansas, and Northern Louisiana this afternoon into the overnight hours as the front stalls out. Moving into Thursday, there is good agreement on both our forecasts and hi- res models in the front backdooring slightly to the west to a line from roughly southeast Oklahoma to the I-20 Corridor of Louisiana. Showers and thunderstorms are expected to remain to the East and South of this boundary. While wider cloud coverage and increased PoPs will help to limit our high temperatures, opted to extend the Heat Advisory areawide through 8 PM Thursday as a moisture pool builds into the area ahead of and along this frontal boundary, keeping dew points and our heat indices elevated.

On Friday our friendly neighborhood ridge is progged to build back over us from the west, pushing out the front and keeping most our zones hot and dry. At the same time, a shortwave will form over the midwest and start to make its way southward. This shortwave will kick out this ridge to the west by Saturday night, bringing along with it increased PoPs along and South of I-20 and near average temps areawide through the end of the weekend. Unfortunately, this relief won't last for too long as by Tuesday of next week, we will see a return to the ridging which is all too familiar. The exact specifics of this ridge will be further nailed down in future forecasts.

AVIATION

(18Z TAFS) Issued at 115 PM CDT Wed Jul 29 2026

For the 29/18Z TAF period, VFR conditions prevail to begin the TAF period as a cu field continues to expand ahead of a weak frontal boundary just north of our airspace. Some high based altocumulus and cirrus decks are also noted along and ahead of the boundary. As this front continues to slowly seep S/SW into our northern airspace, will be watching for possible convection at our S AR terminals closer to 30/00Z and possibly farther south toward I-20 at KMLU/KSHV into the early evening hours. However, given low confidence of this scenario, have opted to only maintain VCTS at these sites and will re-evaluate with the next TAF cycle or handle with amendments if that becomes necessary prior to 00Z. Otherwise, expect much of this cloud cover to linger overnight with the boundary still making further progress into our airspace. However, cigs should remain VFR, albeit low VFR in some cases as the cu/altocu decks will likely maintain or even increase in coverage. Winds will maintain W/SW component ahead of the front between 5-10 kts before trending light and variable later in the period on Thursday morning with the boundary stalling out.

SPOTTER INFORMATION STATEMENT

Issued at 1227 PM CDT Wed Jul 29 2026

Although spotter activation is not expected over the next 24 hours, an isolated strong thunderstorm or two can't be ruled out, as scattered showers and thunderstorms backdoor in with our cool front. /24/
