  Inexperienced mariners and those operating small craft should
  avoid navigating in rough conditions.

- Sunny skies and warm temperatures are on tap at least through
  the weekend. With a lot of outside activities like sports and
  festivals, sun and temperature related health risks are present.
  Make sure you are using sunscreen and drinking enough water.

- Potential exists for development of dense fog toward sunrise
  Sunday as well.

.UPDATE...
Issued at 634 PM CDT Sat Apr 11 2026

Interesting forecast regarding fog development overnight. Mid-
afternoon dew points were in the lower to middle 50s for much of
the Interstate 10/12 corridors. However, forecast lows are well
above that point, so while we are expected to have clear skies and
light winds, confidence in fog development isn`t as high as last
night. We`ll see how hourly temperature trends respond after
sunset, but there are no imminent plans for any advisories.

.SHORT TERM...
(Now through Sunday)
Issued at 1243 AM CDT Sat Apr 11 2026

Surface high pressure continues to dominate the local weather.
This will bring sunshine and above normal high temperatures that
will begin reaching into the mid 80s as we move into the new
week. Overnight lows will also be on the above-normal side ranging
into the mid 60s. Supporting all this is developing upper level
high pressure centered over the Gulf.

&&

.LONG TERM...
(Sunday night through Friday)
Issued at 1243 AM CDT Sat Apr 11 2026

Surface and upper level high pressure continue to
dominate through the long term. Unfortunately, this means the
next rainfall is not in the foreseeable future, so our dry period
and drought conditions will continue. The one possible exception
to this is the possibility of a shortwave on Thursday that could
provide enough lift to generate some showers. Temperatures will
continue to be above normal with highs creeping to near 90 in
places.

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Sat Apr 11 2026

All forecast terminals VFR and are expected to remain that way
through at least 06z. Main concern overnight will be radiation
fog development potential. As noted in the update section above,
afternoon dew points vs forecast overnight lows would argue
against development. If there`s going to be favored terminals, it
would be at KGPT/KASD/KHDC/KMCB. The fact that those areas can get
cooler than expected in regimes like the current one means it`s
not a slam dunk decision. Will carry several hours of MVFR
visibilities at those terminals from about 10z to 13z with TEMPO
IFR, but if temperatures get cooler than forecast, we`ll need to
amend to LIFR or VLIFR. As soon as we get any heating/mixing
Sunday morning, the fog will dissipate, with VFR the remainder of
the day.

.MARINE...
Issued at 1243 AM CDT Sat Apr 11 2026

Strong surface high pressure from the northeast gulf into the
Atlantic continues to produce a moderate easterly to southeasterly
fetch over the northern Gulf. Rough marine conditions with winds at
15+ kt are present and expected to continue in our western
offshore waters through the weekend prompting issuance of Small
Craft Exercise Caution headlines. Conditions will improve slightly
into the new work week as winds ease to around 10kt.
