.DISCUSSION...
Issued at 1153 PM CDT Mon Aug 3 2026

Clear to partly cloudy skies and warm temperatures anticipated 
tonight with lows in mainly in the mid to upper 70s inland and the
upper 70s to lower 80s along the coast. There is a chance for 
some isolated patchy fog early Tuesday morning, but chances are 
low. Fog, if any, will burn off quickly shortly after sunrise. 

Weather conditions will remain hot and on the dry side through 
mid-week as the mid to upper level ridge remains situated over 
Arizona, New Mexico, and extends into Texas. Expect the highs to 
peak in the upper 90s inland (some isolated spots reaching 100 deg
F) and the lower to mid 90s along the coast through Wednesday. 
Heat indices will peak between 103-108 deg F...thus, make sure to 
continue to protect yourself, your loved ones, and pets from the 
heat. From Thursday into the upcoming weekend, the highs are 
expected to range in the lower to mid 90s inland (although some 
spots could peak in the upper 90s) and the upper 80s to lower 90s 
along the coast. 

Subsidence will help limit rain chances early in the week. 
Slightly better chances for showers (20-40%) are expected mid week
into the upcoming weekend as surface moisture moves in from the 
Gulf waters and increases PWs. A good portion of these showers 
are expected to develop near/along the seabreeze during the 
afternoon to early evening hours.

.AVIATION...
(12Z TAF Issuance)
Issued at 516 AM CDT Tue Aug 4 2026

Satellite and observations reveal low-end MVFR ceilings currently
over CLL and approaching UTS early this morning. Can't entirely
rule out these reduced ceilings extending into CXO by sunrise.
Additionally, periods of patchy fog have brought reduced
visibility to LBX as well. VFR conditions will return area-wide by
15Z. Light SSW winds this morning will become S to SSE in the
afternoon with wind speeds approaching 8-12 kt. Isolated SH/TS
possible this afternoon between 21Z-01Z mainly around the Houston
metro terminals. Winds trend back towards light and variable
overnight with potential for another round of patchy fog and
reduced ceilings mainly west of I-45 going into Wednesday morning.
Ceilings/visibilities improve back to VFR by 15Z on Wednesday with
S to SE winds around 8-12 kt prevailing. Another round of isolated
afternoon SH/TS will be possible.
