- Temperatures will be slightly cooler today, but a warming trend commences for Tuesday through the rest of the week.

DISCUSSION

Issued at 1211 AM CDT Tue Apr 21 2026

An upper-level disturbance will traverse central and east Texas today, serving as the primary catalyst for increased convective activity. Expect shower and thunderstorm chances to increase throughout the day, focused primarily across our east Texas counties, although some of this activity could bleed over into southeast Oklahoma, southwest Arkansas and northern and central Louisiana. This setup will yield a notably tight thermal gradient across the ArkLaTex with mid 60s common across east Texas, where persistent cloud cover and precipitation will inhibit heating. Elsewhere, temperatures will successfully climb into the 70s, with some lower 80s possible across our far eastern zones. By Wednesday, robust low-level moisture advection will broaden the threat, supporting scattered showers and thunderstorms that could encompass much of the region, although the higher chances will remain across our western half of the region. Highs on Wednesday will be slightly more uniform, ranging from the mid 70s to around 80 degrees.

Looking ahead into the late week, the 80s will return to the entire region on Thursday and should persist this way into the weekend. While the setup for convection appears much less favorable on Thursday, attention will shift to an approaching surface front on Friday. Although the boundary is expected to stall before reaching our area, we anticipate some convective development across some of our northern zones. The environment warrants watching, with ample CAPE, steep lapse rates, and decent wind shear that would help the develop of stronger storms. That being said, there is limited upper-level support with this and it does appear that there will be some CAP which could be a limiting factor. Given the uncertainty, we will continue to monitor the evolution of the system. SPC currently maintains a 15% (Slight Risk) for portions of our northern zones. Disagreement remains in the forecast for Saturday through Monday, but additional rainfall chances remain on the table through early next week. /33/

AVIATION

(12Z TAFS) Issued at 641 AM CDT Tue Apr 21 2026

For the ArkLaTex terminals, VFR should prevail for AR/LA, but rainfall arriving overnight will bring down cigs to MVFR/IFR by later in this cycle with additional showers stalling over more of the region. Isold TS will be possible by late morning as this weak disturbance moves over E TX and will hang around for a few days with more scattered convection through this week and even more so into the weekend. SFC winds will veer light E/SE for another hour or two, but increase to SE 5-15KT by mid morning. /24/
