.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...
(12Z TAF Issuance)
Issued at 557 AM CDT Wed Aug 5 2026

Current satellite imagery depicts MVFR/IFR ceilings developing
over areas along and west of the Brazos River. These reduced
ceilings are anticipated to move into CLL and UTS over the next
couple of hours and may extend into CXO and IAH as well later this
morning. Additionally, periods of patchy fog have brought reduced
visibility to LBX as well. Based on yesterday, SGR may also experience
reduced visibility for a few hours around and shortly after 
sunrise. 

VFR conditions will return area-wide by 15Z. Light south-southwest 
winds early this morning will become southerly by the afternoon 
with wind speeds in the 8-12 kt range. Occasional gusts of 15-20
kt will be possible through the afternoon. Isolated SH/TS 
possible again this afternoon between 21Z-01Z mainly around the 
Houston metro terminals. Winds become light and variable 
overnight with potential for another round of patchy fog and 
reduced ceilings mainly west of I-45 going into Thursday morning.
Ceilings/visibilities improve back to VFR by 15Z on Thursday with
south to southeast winds around 8-12 kt prevailing. Another round
of isolated to scattered SH/TS possible in the afternoon.

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

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.
