KEY MESSAGES

Updated at 537 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

(12Z TAFS) Issued at 537 AM CDT Fri Jul 3 2026

A mix between MVFR and VFR conditions is mainly ongoing across the region early this morning with the formation and expansion of a sct to bkn deck of low clouds generally with ceilings between 1000 and 2000 feet. KSSF has briefly become IFR and that could persist for another hour or so. The low clouds will be slowest on reaching the Rio Grande, including at KDRT, but may be possible beyond sunrise. Conditions return to VFR levels all sites by mid to late morning and will continue through Friday evening. Low clouds then return from overnight into Saturday morning with MVFR ceilings. Winds remain of light to moderate speeds, mostly from the south to southeast.
