.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...
(06Z TAFS)
Issued at 1142 PM CDT Sun Aug 10 2025

VFR conditions should continue overnight and into Monday. By
afternoon showers and thunderstorms will again start to develop.
Coverage (as we have seen today) is still in question, so mostly
kept PROBs going through the afternoon. If coverage does appear
to increase on Monday, this may be adjusted a bit to represent
that in subsequent updates. Otherwise, outside of brief VIS/CIG
reductions within convection VFR should prevail with generally
light winds below 10kts. (Frye)

.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)
