.DISCUSSION...
Issued at 1150 AM CDT Fri Aug 29 2025

There are only a few minor changes to the forecast for this
weekend through next week. Heat impacts will remain the greatest
concern for this holiday weekend with heat index values
approaching 110 for a large portion of South Texas Saturday and
Sunday. Please use caution when spending time outside this
weekend: take breaks in the shade, drink plenty of water, and
spend time in the air conditioning as often as possible.

By late this weekend, the ridge axis will move to the west. A few
mid-level shortwaves will ride along the eastern periphery of the
high which, when combined with a stationary front over Texas and
sufficient moisture (PWAT 2 inches or more) will lead to an
increased chance for convection. Currently have low to medium
(20-60%) chances of showers and thunderstorms across South Texas
Sunday into Monday. A few storms could produce high rainfall
rates leading to a localized risk of flash flooding--mainly in
low-lying and/or poor drainage areas. WPC continues to highlight a
Marginal Risk (level 1 of 4) of Excessive Rainfall Sunday through
Tuesday morning. Rain chances will diminish by mid-week as the
boundary finally begins to work its way south bringing drier air
with it.

Just a quick note on the forecast rain: Have continued our
forecast as it has been, though I did lower PoPs just a hair as I
have concerns that the bulk of the moisture could remain to the
north of the area.

.AVIATION...
(00Z TAFS)
Issued at 608 PM CDT Fri Aug 29 2025

VFR conditions are expected through the TAF cycle. Have not
included any mention of reduced VSBYs or CIGs, though we could
see some MVFR conditions in the pre-dawn/early morning hours,
particularly for ALI and VCT. South-southeasterly 10-15 knot
winds, with gusts to around 20 knots, will diminish to become
light and variable overnight tonight increasing once again by
Saturday afternoon. A low chance of showers and storms across the
Victoria Crossroads tomorrow afternoon prompted the inclusion of a
PROB30 group for -TSRA from 18Z to 24Z at VCT.

.MARINE...
Issued at 1150 AM CDT Fri Aug 29 2025

Gentle to moderate (BF 3-4) onshore flow with occasionally fresh
(BF 5) breezes along the southern bays and nearshore waters will
continue through the weekend. Rain chances will become low to
medium (20-60%) Sunday through Monday night. Chances will diminish
Tuesday as a boundary moves south through the waters, shifting
winds to the north and bringing in drier air. Winds will return to
onshore flow by Wednesday.
