.DISCUSSION...
Issued at 1204 AM CDT Sat Oct 4 2025
With a large upper ridge remaining in place over most of the CONUS
east of the Rockies, along with the influence of a large surface
high in the Mid-Atlantic region, expect dry conditions to remain
in the forecast today. Light winds, mostly clear skies, and a
drier airmass in place, will allow temperatures to fall into the
upper 50s to lower 60s this morning. As we move into the remainder
of the day, winds will become more easterly, giving us a slight
uptick in low-level atmospheric moisture over the region. This
will result in the development of an expansive CU field during the
afternoon hours. Afternoon highs will remain similar to Friday,
with temperatures generally ranging from the mid 80s to around 90
degrees.
From Sunday through the first couple of days of next week, the upper
ridge will slide eastward along with the Mid-Atlantic surface high.
At the same time, an easterly wave/upper-level disturbance, which
has been lingering across the northern Gulf near the Louisiana
coast, is expected to shift northward and onshore across South
Louisiana during this period.  This will bring a return in rain
chances across the forecast area on these days. Most of the rain is
expected to be confined to our Central and Northeast Louisiana zones
on Sunday, before expanding northward across most of our forecast
zones on Monday and Tuesday. By the middle of next week, an upper
trough will dive south across the CONUS.  This will push a cold
front into our area on Wednesday, keeping rain chances in the
forecast. In wake of this front, dry weather will return, as upper
ridging is expected to build back into the region from the
southwest. /20/

.AVIATION...
(06Z TAFS)
Issued at 1222 AM CDT Sat Oct 4 2025
With drier air having settled in across our airspace attm, IR
satellite imagery showing clear skies across the entire Four State
Region. A tongue to somewhat higher pwat will be retrograding from
east to west across our airspace today. That moisture will combine
with daytime heating for at least a weak cu field across most of
our airspace and have accounted for that in the 06z TAF package.
Any cu field will have dissipated near or shortly after 00z this
evening. Otherwise, VFR conditions will prevail during this 24hr
TAF package.
