...NewARINE... .KEY MESSAGES... - Seasonably hot conditions will continue through the weekend. Peak heat index values between 102-107F (39-42C) through Sunday.

- Moderate to high rip current risk along area beaches through the weekend.

- Rain chances re-enter the forecast heading into the middle parts of next week.

Issued at 1242pm CDT Fri Jun 26 2026

No significant changes were made to the ongoing forecast. Mid-upper ridging will dominate through the weekend. Though a short lived rogue shower can't completely be ruled out, subsidence aloft will largely inhibit precipitation chances. Temps will generally be around, or just slightly above, seasonable norms (highs in 90s, lows in the 70s to around 80). Though heat indices and WBGT values should remain below advisory criteria, those with outdoor plans should still take the necessary precautions to avoid heat stress.

Mid-upper ridging centered over the central Gulf states should strengthen and gradually lift north-northeast going into the mid and late parts of next week. This should allow for some weak disturbances to move westward under the ridge toward the upper Texas coast. Since subsidence shouldn't be quite as dominate, we'll the return of isolated-scattered shower/thunderstorm chances to the forecast. 47
