.DISCUSSION...
Issued at 1240 AM CDT Thu Jul 30 2026

The weakening of the eastern periphery of a large upper ridge,
that brought us hot and dry weather over the past several days,
allowed a weak cool front to backdoor into the Lower Mississippi
Valley, as a deep trough has settled across the eastern CONUS.
Although the front didn`t quite get into our forecast area,
showers and thunderstorms that developed along the front were
able to move into portions of our SW Arkansas zones and the
northern half of McCurtain County, OK. This convection has finally
diminished and conditions should remain quiet over the next
several hours. However, as we move through the overnight period,
the front will continue backdoor into our forecast zones. Progs
suggest the southwestward movement of the front will come to a
halt somewhere near a line from Southeast Oklahoma to near
Texarkana to around the I-20 corridor of North Louisiana Thursday
afternoon. Showers and thunderstorms are expected to develop
again over the area, with the best chances during the afternoon across
McCurtain County Oklahoma, all of SW Arkansas, and along and east
of the Interstate 49 corridor of our Louisiana parishes. Although
the synoptic set-up isn`t great for severe weather, an isolated
strong to severe thunderstorm with damaging wind gusts can`t be
ruled out, along with some locally heavy rain. Hot and humid
conditions will remain in place ahead of the expected rainfall,
so the current Heat Advisory has been extended until 8 PM Thursday
evening.

By Friday, the front will retreat back to the northeast, as the
aforementioned ridge will try to re-establish itself over the
region. This will bring a return of hot and mostly dry conditions
areawide, and the possibility of another areawide heat advisory.
But, this pattern will be short-lived, as the center of the ridge
will shift westward. With the deep trough remaining across the
eastern CONUS, the upper pattern over the region will become more
northwesterly. Models continue to suggest the northwesterly flow
will drive another weak cool front into the region over the
upcoming weekend, with the front eventually stalling south of the
I-20 corridor on Sunday. Rain chances are expected to return with
this front, with the best chances each day along and south of the
Interstate 20 corridor. The front is expected to wash out by early
next week, with upper ridging returning across the region. This
would bring a return in hot and dry conditions for the first half
of next week. However, long-term progs are trying to hint at some
afternoon rain chances in our Eastern Louisiana zones next
Tuesday and Wednesday. /20/

.AVIATION...
(06Z TAFS)
Issued at 1240 AM CDT Thu Jul 30 2026

For the 06z TAF cycle, precipitation has just about dissipated late
this evening across our airspace. The exception to this is north of
the I-30 Corridor but it`s well north of the TXK terminal and should
continue dissipating as we get closer to midnight. Otherwise we are
left with lots of high mid and high cloud cover across our airspace
and that will continue through the next 24 hours. Continued the
trend of VCTS mention tied to daytime heating once again across all
terminals with the exception of the TYR and LFK terminals. A
backdoor cold front remains stalled out across our region near an
Idabel to Texarkana to Natchez line this late hour Wed Evening and
it appears to stay there through this TAF period as well. It`s near
and in the wake of this boundary where isolated to widely scattered
convection will be possible in the 3pm to 10pm timeframe on
Thursday.

.SPOTTER INFORMATION STATEMENT...
Issued at 1240 AM CDT Thu Jul 30 2026

Although spotter activation is not expected over the next 24
hours, an isolated strong thunderstorm or two can`t be ruled out,

front. /20/
