KEY MESSAGES

Updated at 126 AM CDT Fri Jul 3 2026

- Seasonably hot temperatures continue through the Holiday Weekend.

- Forecast trending drier and hotter for next week.

SHORT TERM

(Today through Saturday) Issued at 126 AM CDT Fri Jul 3 2026

The local area sits between an upper level ridge to the east and an inverted upper level short wave trough overhead early this Friday morning. At the surface, a high pressure ridge dominates the region and brings a moist southerly Gulf flow to South Central Texas throughout the overnight and Friday morning period. Clouds are forecast to develop and spread across most areas overnight through at least mid to late Friday morning. Clouds lift and give way to partly cloudy and mostly sunny skies in the afternoon. Forecast highs to reach the mid to upper 90s over most locations and up to 100 along the Rio Grande Plains. Heat index values ranging from 100 to 107 along and east of Interstate 35 corridor including the Coastal Plains and the Rio Grande. Can't rule out a few spots getting into the 108 mark over the Coastal Plains for an hour or two. Also, a few showers are possible to come across the Coastal Plains mid to late morning and again mid to late afternoon.

Weather models continue to show a drier trend for Saturday as the inverted short wave weakens and the subtropical high over the southern Plains strengthens. With that said, another dry and hot day is in store for Saturday with highs in the mid to upper 90s over most locations and up to 101 degrees along the Rio Grande Plains.

LONG TERM

(Saturday night through Thursday) Issued at 126 AM CDT Fri Jul 3 2026

The subtropical high continues to control our local weather with persistent dry and hot conditions. By the middle of the week, the upper level ridge gets stronger and daytime highs are forecast to increase a few degrees more than highs earlier in the week. High temperatures are forecast to reach the upper 90s and up to 101 degrees along and east of Interstate 35, the Coastal and Rio Grande Plains areas. Elevated heat index values are forecast for the I-35 corridor, Coastal and Rio Grande Plains areas through the extended forecast period.

AVIATION

(06Z TAFS) Issued at 126 AM CDT Fri Jul 3 2026

Low clouds will begin to develop and expand across portions of the region shortly. This should result in a mix of MVFR and VFR conditions for portions of the region from the overnight through about mid-morning. KDRT will be slowest to see the low clouds arrive, sometime near or after sunrise. Conditions then return to VFR levels by mid to late morning and will continue into Friday night. Low clouds then return after midnight towards Saturday morning with MVFR conditions possible at the 30 hour TAF sites (KAUS and KSAT). Winds will otherwise remain of light to moderate breezes from the south-southeast to east-southeast.
