.DISCUSSION...
Issued at 1059 AM CDT Wed Aug 12 2026

Starting off with early this afternoon, seeing a few shallow
showers developing inland, as well as a few anchored to SW/NE
boundaries in nearshore marine areas. Latest NBM PPI grids from
the 13Z guidance supports this well, as CAMS continue to support
best rain chances along/north of the I-10 corridor. A few that
interact/anchor to the seabreeze boundary aided by greater
forcing could grow tall enough to become thunderstorms with time.
Regardless of nearby high pressure, the vertical column/thermal
profile according to proximity soundings remains rather moist
adiabatic, with a slug of enhanced tropospheric moisture locked in
across SE LA, east to our general area. But we`ll see all
activity come to an end later on around sunset once we lose
diurnal support.

Generally quiet tonight, then another hot one coming up tomorrow.
Did pay close attention to afternoon dewpoints, implementing a
more realistic PBL mixing regime and lowering inland dewpoints a
few degrees. Wanted to do this first before looking at MaxApt
values which even after the fact, clearly places us in Heat
Advisory criteria for the I-10 corridor. Now farther inland,
especially across interior AL along the I-65 corridor, yes,
greater deep mixing could prohibit reaching criteria (moreso
104-107), but did not want to split hairs and obscure the
messaging that impacts will be increasing starting tomorrow for
those spending time outdoors. The upper-level ridge center
overhead continues to retrograde west, with remnant energy over
the Ohio Valley region to rotate south into AL/GA, in conjunction
with building tropospheric moisture to enhance afternoon
shower/storm coverage. NBM PoPs are targeting greater coverage
for mainly eastern areas, which appears plausible given
aforementioned reasoning. A few storms could be locally strong,
with strong gusty winds the main risk. Will monitor that.

Friday through the weekend, the main key message will be the
heat, with heat headlines likely to persist. Otherwise, will
monitor this same mid-level impulse, then drifting west along the
northern Gulf coast that could aid in dynamic lift to support a
bit greater, mainly late morning into afternoon scattered
shower/storm coverage, particularly on Saturday. A few storms may
be locally strong to severe depending on how storms behave across
intersecting boundaries enhancing localized ascent, but will
monitor.

Next week, the heat continues with no real major changes in the
impacts. Afternoon heat indices in the 106-110 range will
persist, with typical mainly afternoon pop-up storm chances. We
could see a bit of a breakdown in the ridge mid-week, allowing a
trending weakness in upper-level heights to support greater
shower/storm coverage and less in the way of the heat, however,
will be able to fine tune that closer especially into early next
week. KLG

.AVIATION...
(00Z TAFS)
Issued at 624 PM CDT Wed Aug 12 2026

VFR conditions are expected with the exception of a few showers
and storms this evening and on Thursday. Winds become light and
variable this evening, then a southwesterly flow at 5-10 knots
develops on Thursday. /29

.MARINE...
Issued at 1059 AM CDT Wed Aug 12 2026

Nearby high pressure will continue to promote light southwesterly to
westerly winds through the forecast period. Waves/seas will remain
light with no impacts anticipated. KLG
