KEY MESSAGES

Updated at 1217 AM CDT Fri Jun 26 2026

- Dry weather along with near to slightly above normal temperatures continue through the weekend and into early next week.

- Elevated heat index values continue, especially along and east of I-35 and across most the Rio Grande Plains.

SHORT TERM

(Today through Saturday) Issued at 1217 AM CDT Fri Jun 26 2026

The mid and upper level subtropical ridge will remain in place across the south-central U.S. and northern Mexico through the end of the week. We expect to see a persistence of dry weather along with near to slightly above normal temperatures across south-central Texas. Highs will range from near 90 in the Hill Country to near 100 degrees along the Rio Grande. Overnight lows will be in the 70s. Similar to the last couple of days, we also expect to see gusty southeast winds continue, mainly during the late morning through early evening hours. The exception to this has been over the higher terrain of the Hill Country where some Texas Tech mesonet sites have shown some gusty conditions persisting through the overnight hours. The gusty winds will serve to increase the mixing and reducing of dew point temperatures in the afternoon hours during peak heating. This should keep heat index values below Heat Advisory levels through Saturday.

LONG TERM

(Saturday night through Thursday) Issued at 1217 AM CDT Fri Jun 26 2026

The center of the subtropical high will gradually shift eastward into the lower Mississippi River valley early next week as a deep upper trough develops over the western U.S. Overall, this pattern will not result in much change to our sensible weather. We expect to see a continuation of near to above normal temperatures and dry conditions for the region. With a fairly persistent area of surface low pressure over eastern Colorado/western Nebraska and Kansas and surface high pressure over the Gulf, we will continue to see gusty southeast winds well into the middle of the upcoming week. As mentioned above, these winds will help mix (lower) afternoon dew point temperatures, which should largely keep most areas below Heat Advisory levels.

AVIATION

(06Z TAFS) Issued at 1217 AM CDT Fri Jun 26 2026

MVFR ceilings are beginning to develop over the Hill Country into the San Antonio metro and should reach all I-35 sites in the next hour or two. Eventually ceilings spread west to KDRT closer to 11Z. Ceilings may briefly lower to IFR for the I-35 terminals near sunrise, then ceilings are expected to scatter mid to late morning similar to previous days. South to southeasterly wind will become gusty this morning through late evening then weaken slightly overnight.
