   increase though Sunday afternoon through Tuesday across the

.DISCUSSION...
Issued at 153 PM CDT Sat Oct 4 2025
As expected, a scattered cu field has developed areawide early
this afternoon across the region, as a result of a tongue of low
level moisture that has advected WNW from the Lower MS Valley. The
visible satellite imagery continues to depict an upper low
spinning off the coast of SE LA, with an attendant sfc low
analyzed via buoy data farther to the SW over the WCntrl Gulf. The
short term progs remain in agreement with the center of this low
drifting a bit farther W tonight, with a NW drift expected with
the sfc low through Sunday as it begins to open up into an
inverted trough as it nears the SE TX coast. Thus, a deeper slug
of low level moisture will begin to increase from SE to NW Sunday
across N LA, and portions of Srn AR/Deep E TX, characteristic of
PW`s of 1.5-1.7+ inches. As a result, the potential for at least
isolated convection will be possible Sunday afternoon over these
areas, with the greater coverage remaining to our S over S LA. If
anything, the increasing cigs will help to cap temps in the mid to
upper 80s Sunday afternoon, but may cool a bit especially later in
the afternoon over much of N LA. Still believe the NBM is too
scarce with pops, and thus have maintained persistence with slight
chance pops extending farther NW into portions of Deep E TX into
NW LA/SCntrl AR. While this should mostly diminish during the
evening, the opening H850 trough will lift N across the area
Monday, and should focus more in the way of scattered convection
through the day especially across N LA/Srn AR. This convection
doesn`t appear to be very deep though, given the extent of dry mid
level air that will spread N with this low level trough passage.
However, cigs will keep max temps below 90 and coolest along/N of
the I-20 corridor, before the trough lifts N out of the area
Monday night.
Adequate low level moisture should persist across the region
Tuesday as the remnants of this weakness aloft continue to
diminish, with flat ridging beginning to build back in from the
Big Bend region of SW TX N and across the Lone Star state before
eventually expanding farther E into the Lower MS Valley. Thus, any
pops Tuesday will become more isolated, with the heat increasing
a touch once again as the ensembles suggest that the ridge aloft
will begin to amplify N across the remainder of the Srn and into
the Cntrl Plains by late week, which could persist through at
least mid-month. This synoptic pattern would help to maintain the
above normal temps in place, as well as the very dry conditions
that have been observed over the last 10+ days.

.AVIATION...
(18Z TAFS)
Issued at 153 PM CDT Sat Oct 4 2025
Afternoon field of cumulus around 5kft is once again the theme to
start the TAF period. Winds across the local terminals are a bit
breezy, trending on the higher side of the 5-10kt range from the
E/SE. Nonetheless, VFR is expected to remain in place through the
remainder of the day, with the CU field turning to SKC by the
evening, and overnight. Again, another routine CU field will
materialize by the afternoon on Sunday. Terminal proximity to an
area of disorganized showers and storms across the northern Gulf may
allow for a few showers and storms to develop tomorrow afternoon.
That being said, current hi-res suggests that this develops outside
of this TAF window and will likely be addressed in the 00z package.
