KEY MESSAGES

Updated at 533 AM CDT Sat Jun 27 2026

- A persistence forecast continues with dry weather and near to slightly above normal temperatures into early next week.

- Gusty southeast winds continue, especially during the late morning through early evening hours.

SHORT TERM

(Today through Sunday) Issued at 1223 AM CDT Sat Jun 27 2026

Little change in the large scale weather pattern will continue to result in a persistence forecast through the weekend. We will keep the forecast dry, but will monitor for the possibility of an inverted, mid-level trough moving in from the south late Saturday into Sunday. This weak feature may provide enough lift to generate some afternoon convection near the coastal plains. However, confidence is low and we will not mention in the latest forecast. Otherwise, look for near to slightly above normal temperatures across south-central Texas with highs from near 90 in the Hill Country to near 100 degrees along the Rio Grande along with overnight lows in the 70s. Gusty southeast winds will continue, especially during the late morning through early evening hours. Some of the higher terrain locations in the Hill Country can expect some intermittent gusty conditions during the overnight hours. The gusty winds and drying of soils will help reduce afternoon dewpoint temperatures and this should result in peak heat index values remaining below Advisory levels.

LONG TERM

(Sunday night through Friday) Issued at 1223 AM CDT Sat Jun 27 2026

The center of the subtropical ridge will become established over the southeastern U.S. early next week as an upper trough deepens over the western U.S. The medium range models suggest some weak upper disturbances on the southern periphery of the upper ridge may move towards south Texas in this pattern. This may result in some isolated afternoon convection near the coastal plains, with a continuation of dry weather elsewhere. Time series plots of low- level thermal fields suggest a slight amplification early next week. This may tack on a degree or two to the temperature forecasts early next week on Monday into Tuesday.

AVIATION

(12Z TAFS) Issued at 533 AM CDT Sat Jun 27 2026

Areas of MVFR ceilings have developed over the region impacting I-35 terminals while KDRT likely remains VFR. Low clouds scatter mid to late morning with VFR conditions expected through tonight before low ceilings form overnight into Sunday morning. South to southeasterly wind increases mid-morning with gusty conditions expected to continue into late this evening.
