.SHORT TERM...
(Tonight through Tuesday night)
Issued at 1142 PM CDT Sun Aug 10 2025

A fairly tranquil night has evolved across the CWFA late this
evening. Our area remains on a rather dry side (at least aloft) of
an H5 weakness across southeast portions of Texas this evening.
With the slight delay in low level moisture, today didn`t really
see as much overage as initially thought. Monday and especially
Tuesday will be the days of transition. Looking upstream, there is
an easterly wave over the southeast Gulf. This feature and the
upper level weakness above it will continue to move toward our
region through the start of the new workweek. This will certainly
enhance the low level tropical moisture and help produce more in
the way of diurnally driven showers and thunderstorms. Right now
the best potential looks to be on Tuesday with plenty of low level
convergence and the upper level weakness overhead. With respect to
higher POPs and cloudiness, temperatures will be held down
slightly below average perhaps with some struggling to reach 90
degrees, especially east of I55. (Frye)

.LONG TERM...
(Wednesday through Sunday night)
Issued at 1142 PM CDT Sun Aug 10 2025

With the surface trough still in closer proximity, rain chances to
start off the long term will remain across the region. That said,
it will not take long for the upper level ridge to spread eastward
from Florida and across the Gulf. Each day as we get closer to the
upcoming weekend, POPs will decrease as the ridge centers over our
region once again. Rain chances will not be zero of course, but
with the 595 dam H5 ridge setting up here shower coverage will be
more limited for sure (below climo POPs for early to mid August).
Speaking up, as we are used to this time of year, as POPs decrease
you can expect those afternoon highs to increase, especially as
the upper ridge centers over the region through the weekend.
Temperatures in the middle and upper 90s will be possible once
again with the potential for heat headlines as early as Friday.

.AVIATION...
(12Z TAFS)
Issued at 644 AM CDT Mon Aug 11 2025

Currently VFR, with most convection offshore. Isolated SHRA/TSRA
could get going as early as 15-16z, but expect most to be this
afternoon. Generally, will carry TEMPO at terminals south of
Interstate 10, and PROB30 at KMCB/KBTR/KHDC, with most dissipating
around sunset. Will carry mention of SHRA/TSRA prior to sunrise
Tuesday at southern and eastern terminals as easterly wave
approaches and spreads precipitation back into the area.

.MARINE...
Issued at 1142 PM CDT Sun Aug 10 2025

Winds and waves are forecast to remain mostly benign through the
forecast period with winds staying below 15kts. The only marine
concerns through the forecast period are related to convection.
Winds and waves will be locally higher around any thunderstorms
that develop. The early morning hours have the best chances of
marine convection each day with some storms on the stronger side
bringing higher winds and seas. Convective coverage is expected to
increase early to midweek before decreasing as high pressure
builds back into the region by the end of the workweek. (Frye)
