DISCUSSION

Issued at 159 PM CDT Tue Jun 9 2026

Another warm and humid day, as upper ridging has settled into the region. This prompted us to issue a Heat Advisory for southeast Oklahoma, and portions of northeast Texas and adjacent southwest Arkansas, as heat index values are forecasted to reach the 105 degree threshold. Despite the ridge in place, a stray shower or thunderstorm can't be ruled out with peak heating this afternoon, especially across our Deep East Texas and adjacent Central Louisiana zones. Currently, we are seeing some isolated seabreeze induced convection across southeast Texas and adjacent southwest Louisiana near the I-10 corridor, which is pushing northward. If this activity makes it into our region, it will likely dissipate around sunset due to the loss of daytime heating. Expect similar conditions over the next couple of days, as upper ridging will remain in place over the region. Afternoon highs will continue to climb into the low to mid 90s. We can't rule out additional heat advisories, as afternoon heat indices will likely range between 100-106 degrees during this period. We could also see more stray to isolated showers with daytime heating, especially on Wednesday across our Deep East Texas and adjacent Central Louisiana zones.

By Thursday night, the synoptic weather patter will start to change, as the aforementioned upper ridge will start to flatten out. This will allow a long-wave trough to dive southward into the region by Friday morning. At the moment, long-term progs halt the southward progression of the trough to the northern half of our forecast area through Saturday. This will likely keep the best rain chances along and north of the I-20 corridor through the first half of the weekend. By Sunday, what's left of the ridge will start to shift westward into the southwest CONUS. Flow aloft will become more northwesterly, driving a cool front into the region late Sunday into Early Monday morning. This will bring widespread rain chances across the region. Previous model runs had the front stalling across the area, keeping rain chances in the forecast for Tuesday. However, the most recent runs are suggesting the front will push through the region. This would bring a return of dry weather, along with slightly cooler and less humid conditions.
