KEY MESSAGES

Updated at 125 AM CDT Sun Jul 5 2026

- Seasonably hot July temperatures continue.

- Low end rain/storm chances early week and next weekend, best chances Monday afternoon/evening from Hill Country to the I-35 corridor

SHORT TERM

(Today through Monday) Issued at 125 AM CDT Sun Jul 5 2026

A mid to upper level trough has moved into the Mississippi Valley with a ridge from northern Mexico to the central Rockies. This is producing weak flow over Texas. Surface high pressure over the Gulf is keeping southeasterly flow in the low levels and a warm, moist airmass in place. A cold front will stall near the TX/OK border and generate thunderstorms over north TX. These storms will generate outflow boundaries that could send some convection into our northeastern area this evening. Otherwise it will be another seasonably hot day and warm night. Monday there will be another round of storms along the stalled front near the Red River. Models are showing a better chance for some storms to move into our northern counties starting during the afternoon Monday and continuing into the evening. Any storms should be confined to the Hill Country and southern Edwards Plateau.

LONG TERM

(Monday night through Saturday) Issued at 125 AM CDT Sun Jul 5 2026

The upper ridge will push the stalled front back northeast, and dry weather will return to our entire CWA for the rest of the work week. Hot and dry weather will be the foreast each day. Temperatures will rise a few degrees by Friday, but heat indices will remain below Heat Advisory levels for most of the CWA. A few spots in the east could reach advisory level each afternoon Thursday through Saturday. Saturday another upper trough will ride over the ridge to the southeast US. This will bring another front north TX. This will bring a chance for showers and thunderstorms to South-Central Texas Saturday.

AVIATION

(06Z TAFS) Issued at 125 AM CDT Sun Jul 5 2026

VFR flight conditions begin the TAF period with some high clouds moving across the region. A batch of low clouds will begin to form shortly and will spread mainly across central portions of the region overnight into the morning, including the San Antonio terminals (KSAT and KSSF) with probably a mix of MVFR and VFR conditions. KAUS and KDRT looks to generally stay VFR during the overnight through the morning. All sites will trend VFR during the latter half of the morning into Sunday night. Some high clouds do continue to move across the region as well. We'll once again monitor for development of low clouds from the overnight into early Monday morning, but kept conditions VFR for now with scattered coverage at the 30 hour TAF sites (KAUS and KSAT). The winds will remain of light to moderate speeds from the south to southeast with peak speeds at around 10 kt with locally higher gusts at times.
