.SHORT TERM...
(Today through Saturday night)
Issued at 1223 AM CDT Thu Aug 28 2025

A few light showers have hung on late this evening
near the coast supported by a weak quasistationary frontal boundary.
While one or two showers can`t be completely ruled out through the
early morning, expect this activity to remain minimal. However,
convection will increase again by late morning with the boundary
providing a focus for slightly above normal PoPs through the
afternoon.

The bigger weather issue in the short term will be a surge of deep
moisture expected to push into the region Friday into Saturday ahead
of another frontal boundary. Widespread showers and thunderstorms
are expected to begin by late Friday morning and continue through
Sunday evening. Coverage may be somewhat lower during the overnight
hours Friday and Saturday, but storms are expected to continue
through the night. The saturated moisture profile will yield
efficient rainmakers capable of producing periods of torrential
rainfall that could lead to nuisance street flooding. WPC has
maintained a marginal risk for excessive rainfall across the entire
region Friday through Sunday. The high rainfall and cloud cover will
moderate afternoon highs which will peak in the mid to upper 80s
over the weekend.

.LONG TERM...
(Sunday through Thursday)
Issued at 1223 AM CDT Thu Aug 28 2025

A frontal boundary will push through the region Sunday
with a somewhat drier and marginally cooler airmass advecting into
the region Monday and Tuesday. Afternoon highs will peak in the
upper 80s with overnight lows ranging from the mid 60s to 70 and
dewpoints in the same range. It`s not quite fall, but it looks to be
a noticeable and somewhat early relief from early September heat.
Long range guidance shows the synoptic pattern of upper troffing
remaining in place across the eastern conus through the end of
next week possibly pushing another noticeable frontal boundary
through the area toward the end of next week.

.AVIATION...
(12Z TAFS)
Issued at 616 AM CDT Thu Aug 28 2025

A few nocturnal showers over the Gulf are heading onshore and may
reach the KBPT/KLFH/KARA terminals before weakening. Also, some
brief patchy ground fog may occur at KAEX before sunrise,
otherwise, VFR conditions are expected.

For the afternoon, with daytime heating, scattered showers and
thunderstorms are expected to develop. Will mention VCTS at all
terminals after 28/18-19z to account for this. Away from any
convection VFR conditions are expected.

.MARINE...
Issued at 1223 AM CDT Thu Aug 28 2025

Light onshore winds will prevail into early Saturday. A slowly
advancing front slides south Friday into Saturday which should
bring about widespread shower and thunderstorm activity. Winds
will turn offshore late Saturday or Sunday through the middle of
next week as the frontal boundary moves off the coast.

&&

.FIRE WEATHER...
Issued at 1223 AM CDT Thu Aug 28 2025

Scattered afternoon thunderstorms are expected Thursday enhanced
somewhat by a weak boundary near the coast. Humidity will increase
significantly Friday through Sunday as moisture surges ahead of another
frontal boundary yielding widespread showers and thunderstorms through
much of the weekend. The front will push through the area Sunday
turning light winds out of the north Sunday through mid next week pulling
some slightly drier air into the region Monday through Wednesday.
