KEY MESSAGES

Updated at 541 AM CDT Wed Jul 1 2026

- Hot and seasonable temperatures continue through the Holiday Weekend.

- Low shower and thunderstorm chances return late this weekend into early next week.

UPDATE

Issued at 541 AM CDT Wed Jul 1 2026

Some streamer showers are showing good organization and a few heavy echoes at times, so have opted to add a couple hours of Pops nearby. New cells continue to form, so another reactive update may be needed in another 30 minutes to an hour to add low chances for showers to more areas.

SHORT TERM

(Today through Thursday) Issued at 1234 AM CDT Wed Jul 1 2026

A 597dm High remains in control over the eastern CONUS, contributing to record heat out east and continued dry weather here in south central Texas. While some seabreeze shower activity cannot be ruled out today and tomorrow, it's more likely to be dry as capping and a lack of forcing keep things in check. Temperatures will climb into the mid to upper 90s both days with heat indices in the 100-106 range, typical for early July.

LONG TERM

(Thursday night through Tuesday) Issued at 1234 AM CDT Wed Jul 1 2026

The ridge slowly starts to weaken and slide eastward closer to the eastern seaboard, allowing flow aloft to weaken slightly and turn a bit more northwesterly by the end of the Holiday weekend. Some low end rain chances will return with this shift in the jet stream, but it doesn't look significant at this distance. After a hotter and drier stretch the past 2 weeks, most would be welcoming to additional rainfall during the start of the hottest month of Summer.

AVIATION

(12Z TAFS) Issued at 541 AM CDT Wed Jul 1 2026

A few streamer showers have popped up east of SAT/SSF. Minimal impacts are expected, but some of the downpours seen on radar would suggest some MVFR or lower VSBYS should new ones pop up closer to the VCNTYs. Broad but ragged coverage of MVFR CIGs continue near all 4 TAF sites, and the plentiful breaks in coverage should lead to rapid mixing and decreases in coverage through 15Z. Similar speeds and directions are projected for the winds over the next day, so we'd anticipate a persisence type of forecast in the handling of the morning MVFR CIGs going forward.
