.DISCUSSION...
Issued at 1132 PM CDT Tue Aug 4 2026

Ridging centered over the Southwest CONUS/Four Corners is expected 
to result in largely uneventful weather over SE Texas through early 
next week at least. The ridge is anticipated to drift north slightly 
beginning Thursday with heights and 850mb temperatures expected to 
drop slightly into the weekend, resulting in a slight downturn in 
heat stress. Decreasing subsidence and rising PWs should bring some 
better rain chances throughout this period, with isolated 
seabreeze/baybreeze showers/storms becoming more scattered in nature 
as a result, especially after today. Overall highs will be in the 
90s each day with heat indices reaching the triple digits in the 
afternoon. Some patchy fog will be possible during the early morning 
hours.

.AVIATION...
(00Z TAF Issuance)
Issued at 710 PM CDT Tue Aug 4 2026

Current VCTS associated with the afternoon sea breeze are being 
monitored around IAH. Remnants of the sea breeze will keep S 
winds elevated around 10 kts, gusting between 15-20 kts. Winds 
will relax becoming variable at 03-05 kts in the early morning 
hours between 05-12Z. Just before sunrise, CIGs and VSBYs could 
drop to MVFR and even VFR at some terminals such as SGR, LBX, IAH,
and CXO due to light winds and overnight moisture supply. After 
sunrise, CIGs will gradually lift and scatter out and fog, if any,
will burn off quickly and return to VFR conditions throughout the
period. Winds will strengthen around 10 kts throughout the 
afternoon out of the S-SE. Sea breeze again brings gusts 15-20 kts
and another round of PROB30 -SHRA, mainly around the I-10 
corridor.

Onshore winds 10-15 knots and seas of 2-4 feet are expected 
throughout the next several days. Rain chances increase slightly on 
Thursday through early next week. Chances for isolated to scattered 
showers and storms will be greatest during the late night through 
early afternoon hours for the Gulf.
