Scattered thunderstorms developed early in the morning on June 23rd within a zone of weak theta-e advection at 850 millibars, from Southwest Oklahoma into Northeast Texas. Rich boundary layer moisture as well as overall strong instability was in place across this region, along with effective deep-layer shear of 35-40 knots.

The episode as NWS SHV wrote it up.
Scattered thunderstorms developed early in the morning on June 23rd within a zone of weak theta-e advection at 850 millibars, from Southwest Oklahoma into Northeast Texas. Rich boundary layer moisture as well as overall strong instability was in place across this region, along with effective deep-layer shear of 35-40 knots. Wind profiles indicated 850 millibar winds out of the south to southeast at around 25 knots, aiding in lift across the warm advection zone. As low-level winds veered and strengthened during the morning hours, forcing for ascent also increased. Slow-moving thunderstorms with heavy rainfall began to rapidly increase in this environment, even extending through the afternoon. Given the high precipitable water (PWAT) environment, localized strong downbursts also occurred with some of these storms. Widespread rainfall amounts of 2-6+ inches fell over Southern McCurtain County Oklahoma from the morning through the evening, contributing to areas of flash flooding. An isolated severe thunderstorm also developed over this area during the evening hours on the 23rd before diminishing. As a result, several reports of flash flooding were recorded across McCurtain County Oklahoma along with an isolated damaging wind report.

- 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.

.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/
