- A few minor changes to the daily temperatures for this afternoon into the weekend and continuing through the middle of next week. - Persistent dry conditions with slightly above normal temperatures for the rest of June into early July 2026.

SHORT TERM

(Tonight through Saturday night) Issued at 1232 PM CDT Fri Jun 26 2026

The short term forecast remains intact for the most part with a few changes on daily temperatures over some locations. Forecast highs range from the low 90s across parts of the Hill Country and southern Edwards Plateau to the mid and upper 90s across the rest of South Central Texas. Can't rule out for Del Rio to get to the 100 degree mark on Saturday. Otherwise, dry and hot with heat index values reaching 100 to 107 along and east of Interstate 35 including the Coastal Plains and areas along the Rio Grande during the afternoons. A southerly wind flow will be dominating the local area with breezy conditions and wind gusts of 20 to 25 mph.

LONG TERM

(Sunday through next Friday) Issued at 1232 PM CDT Fri Jun 26 2026

An upper level ridge is in controls of the local area weather through the extended forecast period. The GFS and ECMWF models bring an inverted short wave trough across the middle Texas coast and then into the Rio Grande Plains on Sunday. In the wake of it, southerly winds increase in addition of Gulf moisture and somewhat Sahara dust. So, breezy and gusty winds of 20 to 25 mph possible.

By Monday, the breezy and gusty conditions persist, however, humidity decreases as an augmented Saharan dust layer pushes across South Central Texas. With dry air in place, daytime temperatures are forecast to increase a few degrees higher than those on Sunday. Also, this setup keeps breezy and gusty conditions across the local area with gusts of 20 to 30 mph possible. Less Saharan dust is forecast for Tuesday, but the heat continues with highs in the mid to upper 90s across most locations.

The upper level ridge moves to the east over the weekend into early next week and establishes over the Lower Mississippi Valley by Wednesday. By then, some increased moisture from the Gulf could be enough for a shower or two or maybe a thunderstorm over the far southeast portion of the Coastal Plains. Similar conditions are in place through the rest of the work week. One more thing to mention, can't rule out a close shower or storm to the west of Val Verde County each afternoon for the next several days as an active dry line lingers over west Texas.
