KEY MESSAGES

- Seasonably hot with highs in the 90s and heat index values 100-107F each day. - An isolated late day shower can't be ruled out along the seabreeze in the afternoons. - Slightly better rain chances expected Thursday into early next week for the eastern and southern parts of the region as some deeper moisture flows back inland.

DISCUSSION

Issued at 103 PM CDT Wed Aug 5 2026

With exception to some light showers in the coastal counties, conditions across the forecast area are dry (rain wise) and warm. We could see some isolated to scattered showers and storms across parts of the area this afternoon, and for the next few afternoons during the work week; however, the ridge aloft centered over the Desert SW will keep a lid on this activity.

Going into the weekend and early next week, the aforementioned ridge will shift more to the west, slightly losing its grip over the eastern and coastal counties. That along with a small bump up in PWATs, and diurnal / seabreeze processes will allow for somewhat higher PoPs in the afternoons.

MaxTs for nearly the entire duration of this forecast period will be at or around their climatological normals for this time of year. With that said and with dewpoints in the 70s, we are not looking at heat indices crossing into heat hazard territory.

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.

Winds and seas will be relatively low in the 10 to 15 kt range and 2 to 4 ft range respectively. A stray shower or two cannot be ruled out during the afternoons, with convective activity more likely towards the end of this work week and into next week.
