- A stationary front will allow for continued rounds of thunderstorms overnight, early Tuesday and potentially lingering with daytime heating over the same areas.

- The Flood Watch is in effect for the overnight hours and for Tuesday for much of the ArkLaTex north of I-20 until 3 PM.

- Temperatures will climb into the mid 90s by late week into the weekend possibly prompting Heat Advisory headlines each day.

DISCUSSION

Issued at 1229 AM CDT Tue Jun 23 2026

Northeast winds across Oklahoma and Arkansas have pinned a now stationary frontal boundary along the Red River of Oklahoma and Texas, and then extending eastward right along the Arkansas and Louisiana state line. We have seen a continued train of showers and thunderstorms, some heavy briefly with confirmed 1 to 2 inch amounts of additional rainfall this evening and more to come overnight. So keep a NOAA WX Radio on duty overnight for any Warnings. The previously issued Flood Watch has been extended for a few northern most counties including McCurtain, Sevier and Howard. In addition, as the front will be lifting back northward on Tuesday, and we have cleared the southern row of counties and parishes from the Watch.

This new Flood Watch area has also been extended in time until Tuesday mid afternoon. We continue with high chance to likely PoPs for the watch area with more heavy downpours expected, due to slow and persistent light NW flow aloft. Our evening balloon sounding continues to show high water content with our PWAT over 2 inches. The WPC continues their Slight Risk for excessive rainfall overnight, then dipping down into NE TX for Tuesday before slowly lifting out the Marginal Risk out of our area late week. Also of note, our surface CAPE remain in the 3-4k J/kg range with our DCAPE over 1000 J/Kg with a Marginal severe threat from damaging winds. The SPC concurs with a Marginal Risk overnight north of I-20 in NE TX into SE OK and S AR and along and south of I-20 in LA. The day 2 indicates this risk will be shifting northward by around daybreak.

Heating will allow additional convection to fire along the remaining cool pool area and lingering outflow boundaries. Otherwise, it will coolest, but still quite warm under the rain clouds across our north, while areas south of I-20 will be bordering on hot again with lower 90s and Heat index values right around the 105 degrees threshold. One thing is for sure, when this front lifts back northward in the afternoon as the upper ridge over New Mexico soars to 597dam by late tomorrow, we will be seeing those hotter temps areawide with likely Heat Advisory headlines going forward into the weekend and early next week. The model forecast temperatures will see widespread mid to upper 90s and until we dry out again, a Excessive Heat Warning may be required for the most humid areas. /24/

AVIATION

(12Z TAFS) Issued at 651 AM CDT Tue Jun 23 2026

Low MVFR cigs have developed across much of E TX this morning, with cigs mostly scoured out over SW AR and much of N LA where deep convection moved through earlier. However, this may be short-lived as additional IFR/low MVFR cigs develop by mid-morning over these areas, with cigs slowly lifting/becoming VFR by midday/early afternoon. Meanwhile, a NW to SE line of deep convection ongoing along a stalled sfc bndry extending from near the Red River of SE OK SE to just W of TXK then S along the TX/LA border will persist through at least mid-morning before gradually diminishing as additional convection development focuses farther W, but still may impact the TXK/SHV terminals through mid/late morning before ending. Elsewhere, the remaining terminals should remain mostly dry, although the presence of this bndry may focus additional isolated to scattered convection late this afternoon through tonight, although low confidence in the timing and location uncertainties remains too low to include VCTS in the TAFs attm. Could see the return of low MVFR or IFR cigs to portions of Lower E TX/N LA by the end of the TAF period, with cigs more likely to fill in briefly after daybreak Wednesday before lifting. S winds 5-10kts today, except VRB around 5kts across SW AR will become light S or Lt/Vrb after 00Z. /15/
