- 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.
