.DISCUSSION...
Issued at 1135 AM CDT Sat Sep 27 2025
A benign pattern is in play across the region as dry conditions
continue to surge southward in the wake of a mid week frontal
passage. Compared to what was messaged in the previous forecast
package, not much has changed. Dry weather with mild temperatures
will continue across the FA through the rest of the weekend and
into the upcoming week. Deterministic output continues to suggest
that a weak 500mb trough axis will continue to slide east across
the SE CONUS, allowing for a more pronounced upper ridge envelope
to evolve across the center of the country. The subsidence aloft
as a result of this pattern can be seen in the 700-300MB RH
profile with percentages in the single digits extending as far
north as the Upper Midwest. This dry air profile is the same layer
that will attempt to dive south across the eastern Gulf and try
to entrain within the newly designated Tropical Depression Nine as
it advances north across the Bahamas and runs parallel to the
east coast of Florida.
Back at home and looking long term, longwave troughing will
extend into the region come late Monday and into Tuesday. As
expressed in the morning package, and with no real change noticed
in the recent guidance available, lack of sufficient moisture to
work with the upper level ascent will suppress any confidence of
precip from this pattern adjustment. That being said, long range
support across the deterministic suggests some form of long wave
troughing that may retrograde across the SE CONUS by the middle
of the week. Much of the guidance, including the latest NBM
continues to suggest that even with the upper level feature, that
we will continue to stay dry locally though PoPs could change if
confidence improves. For now though, a dry and mild period is
expected through the next 7 days.

Conditions will remain VFR through the period. Most of our
afternoon cu field has dissipated with some high cirrus hanging on
on Deep East Texas. Skies should stay mostly clear overnight with
calm/near calm winds. Another cu field should develop around
midday tomorrow with increasing winds: generally northeasterly at
around 7 kts. Areas east of I-49 should see slightly higher winds
compared to elsewhere, but nothing is looking too gusty at this
time. /57/
