  Sunday as well.

.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...
(18Z TAFS)
Issued at 1243 AM CDT Sat Apr 11 2026

VFR conditions present across the area are expected to stay in
place into the early morning hours. Then, reductions in cigs and
vis to IFR are possible due to low stratus or fog.

&&

.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.
