KEY MESSAGES

Issued at 325 PM CDT Tue Jun 2 2026

- Scattered thunderstorms will be relatively widespread across the area in the vicinity of a southward-moving cold front. A few storms could become severe through this evening posing a threat for damaging winds and large hail.

- Daytime high temperatures will be near seasonal norms, generally in the 80s, Wednesday through Sunday before most locations warm into the lower 90s early next week.

- Chances for thunderstorms will remain in the forecast each afternoon across portions of the area through the beginning of next week. The best chances for widespread rains should be Saturday and Sunday afternoons.

DISCUSSION

Issued at 325 PM CDT Tue Jun 2 2026

Scattered strong to severe convection is ongoing generally between the Interstate 20 and 30 corridors across Northeast Texas, Northwest Louisiana, and Southwest Arkansas. These storms are developing along a couple of residual outflow boundaries and ahead of an advancing cold front. The 18z KSHV raob indicated strong surface-based instability in excess of 4000 J/kg and an uncapped atmosphere. The strong buoyancy has been enough to overcome very weak deep layer shear to build deep, robust convection. A severe weather threat will likely persist through the evening hours until the convection and the cold front exit to the south of the forecast area. Damaging winds will continue to be the primary threat. Inverted-V forecast soundings and high PWAT values suggest high likelihood of wet microbursts. However, large hail will also be a threat with the tallest and more organized storms. These storms have also been extremely efficient rainfall producers. Given the somewhat slow movement of the storms, flash flooding may become a concern, especially in urban locations and flood-prone areas.

Northeast winds behind the front will usher some cooler air into the region helping to bring daytime high temperatures back down to near seasonal norms. High temps will generally hold steady in the 80s from Wednesday through the weekend before a slow warming trend returns early next week. Chances for showers and thunderstorms will be in the forecast each afternoon with maximum convective coverage expected during peak diurnal heating.

Surface and upper ridging will move into the Southeast CONUS late this week allowing deep southerly flow to return to the area. As deep layer moisture surges north, one shortwave trough will move northeast across the Southern Plains Friday, followed by another, stronger, and slower moving trough Saturday and Sunday. With ample instability and deep layer moisture and weak capping, showers and thunderstorms are likely areawide during the afternoon and evenings Saturday and Sunday. Broad vertical ascent and the lack of a front to serve as a focus mechanism means convection could develop pretty much anywhere, although the best chances for rain should be over Southeast Oklahoma and East Texas where vertical ascent will be greatest.

Rain chances will likely persist into early next week as weak upper ridging develops over the Central CONUS.

AVIATION

(18Z TAFS) Issued at 1242 PM CDT Tue Jun 2 2026

For the 02/18Z TAF update, TSRA/VCTS continues to rapidly develop across the airspace with some gradual southward propagation expected through 03/03Z before dissipation. This TSRA convection will produce some localized MVFR vis/cigs through the same time period. By 03/12Z, some patchy MVFR/IFR vis/cigs will be likely through 03/15Z. /16/

SPOTTER INFORMATION STATEMENT

Issued at 325 PM CDT Tue Jun 2 2026

Spotter activation may be needed through this evening south of the Interstate 30 corridor, mainly across Louisiana and East Texas.
