What happened

The episode as NWS SHV wrote it up.

An upper trough shifted southeast from Illinois across the Ozarks into East Texas during the afternoon of September 4th, which reinforced a weak surface front south into Southeast Oklahoma and Western/Central Arkansas. Afternoon temperatures climbed into the lower 90s just ahead of the front over Southeast Oklahoma and Southwest Arkansas, with adequate low level moisture present resulting in moderately unstable conditions. This trough increased large scale forcing along the front and within the moderately unstable environment, with isolated to widely scattered showers and thunderstorms developing over Southeast Oklahoma and the northern sections of Southwest Arkansas. One isolated severe thunderstorm did result over Northern Sevier County, which produced damaging winds that downed power lines in Gillham before weakening early in the evening.

.SHORT TERM...
(This evening through Monday Night)
Issued at 227 PM CDT Sun Sep 4 2022

Partly to mostly cloudy this afternoon with Tyler the hot spot at
93 degrees and still on the fringe of a large cirrus shield.
Elsewhere, under the clouds we see mid to upper 80s. Our winds
are light and variable and that will continue as the front is not
doing much any longer but dissolving. The troughing in the MS
River valley is shipping another core into the base over OK for
the most part right now. This low will be our friend for fighting
the drought and normal summer temps for the week ahead. However,
with the clouds today we are quite stable, but the approaching
low is helping to facilitate some new lift now with peak of
heating in progress and development that will linger into the
evening in SE OK and NE TX. Overall, we will see more convective
activity tomorrow than today and little change on temps for now
with more lows around 70 degrees and highs for our Labor Day
holiday back close to 90. If thunder roars, go indoors. /24/

.LONG TERM...
(Tuesday through next Saturday)
Issued at 227 PM CDT Sun Sep 4 2022

Not too often I can talk about this in an active pattern. My last
midnight shift was Wednesday morning, and here we are Sunday, and
not much has changed from my forecast then until now. That is a dish
typically served with the ridging pattern we find ourselves in
during the summer. While the ridge is certainly helping to dictate
this forecast, it's not the typical hot/dry scenario that usually
comes along with it.

Upper-level troughing remains comfortably in place over the region,
sandwiched between a relentless ridge over the Rocky mountains, and
the the Bermuda High. These two features look to hold this trough in
place for the long haul. It only looks like this pattern begins to
break down into next weekend, as an even larger trough begins to
move through the Great Plains. It doesn't look like this larger
trough will have an immediate effect on the region, but it could
certainly influence us down the stretch. What that means for us in
the interim is continued divergence aloft, resulting in consistent
afternoon rain chances. These rain chances will continue to be
highly influenced by peak daytime heating, and should diminish after
sunset. Locally heavy rainfall will continue to be possible with
these thunderstorms, as PWAT values will remain stout as well. Given
these rain chances and afternoon cloud cover, temperatures this long-
term will just be slapping the persistence button. Afternoon highs
should range in the mid-80s, with overnight lows ranging in the
upper-60s to low-70s. /44/

Increased instability combined with a moist environment will
maintain an unsettled weather pattern across the region through
the terminal forecast period ending 06/00Z. VCTS conditions to
improve through the early evening hours with IFR/LIFR ceilings and
VSBYs possible across some terminals near daybreak. Conditions to

This Hazardous Weather Outlook is for south central Arkansas,
southwest Arkansas, north central Louisiana, northwest Louisiana,
southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...Today and tonight.

Isolated to widely scattered showers and thunderstorms are expected
this afternoon into early this evening across the Four-State region.
Some of these slow-moving storms will be capable of producing locally
heavy downpours which could result in minor flooding of low lying and
poor drainage areas. Gusty winds and lightning may also accompany any
heavy downpours. If thunder roars, go indoors is a good reminder this
holiday weekend.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Isolated to scattered, mainly afternoon, showers and thunderstorms
are expected on Labor Day. The minor flooding threat will continue
with very moist soil conditions and the potential for slow-moving
thunderstorms to drop a quick one to two inches of rainfall in very
isolated locations. Expect this forecast to be repeated through most
of next week as daily rain chances will persist under an upper-level
trough pattern. Once again, gusty winds and dangerous lightning may
continue to accompany any heavy downpours throughout next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
