.DISCUSSION...
Issued at 1022 PM CDT Fri Jul 18 2025

Hot and generally rain free conditions are expected through the
forecast. Rain chances look to remain below 10%, though a couple
brief showers along the sea breeze, or overnight streamer showers
can`t be ruled out. An upper-level ridge looks to remain over the
Central US through the next 7 days, possibly building
northwestward next week. This pattern will likely support a broad
area of persistent subsidence across the region. At the surface,
southeasterly flow will continue to advect warm, humid air to the
region. Combined with generally mostly sunny skies, this will lead
to a gradual warming trend this weekend and early next week. High
temperatures will likely range from the upper 90s to low 100s
through the forecast, with low triple digits becoming more
widespread early next week. Heat indices look to largely remain
between 105-108, though brief spikes to 110-112 are possible. The
short duration of higher heat indices will likely not warrant any
Heat Advisories through the forecast.

.AVIATION...
(12Z TAFS)
Issued at 606 AM CDT Sat Jul 19 2025

After brief MVFR early this morning, VFR will prevail at all
aerodromes for the remainder of the day. Light winds around
sunrise will become breezy today before diminishing early this
evening. No precipitation is anticipated.

.MARINE...
Issued at 1022 PM CDT Fri Jul 18 2025

Generally favorable marine conditions are expected to continue
for the Gulf waters. Light to moderate southeasterly winds and
slight seas will likely persist through the forecast, with high
pressure firmly in place across most of the Gulf. Closer to
shore, some increase in wind speed is likely each afternoon as
pressure gradients along the coast tighten in response to daytime
heating. This may result in wind speeds along the Laguna Madre
reaching 15-20 knots during the afternoons this weekend and early
next week. The best chance for higher wind speeds, and resultant
Small Craft Should Exercise Caution headlines will likely occur
Sunday or Monday afternoon.
