KEY MESSAGES

Updated at 646 PM CDT Sat Jul 18 2026

- Drier conditions through next week.

- Seasonably hot conditions with a moderate to major risk of heat- related impacts through next week. Peak heat indices will range between 100-110 degF.

DISCUSSION

Issued at 126 PM CDT Sat Jul 18 2026

A mid-level ridge will build over the region through the weekend and persist into next week, promoting hotter, drier, and more stable conditions. Other than an isolated seabreeze shower or storm near the coast, most locations are expected to remain dry through at least the first half of the week. Meanwhile, any lingering river flooding across portions of South Central Texas will continue to work downstream, including the Nueces River, Frio River, and the Rio Grande.

Temperatures will steadily warm through the forecast period, with highs slightly above normal and the hottest conditions expected across the Rio Grande Plains and Brush Country. Heat index values will generally range between 100-110 degF, supporting a moderate (level 2 of 4) heat risk across much of the region with isolated pockets of major (level 3 of 4) heat risk. Moderate south- southeasterly winds will persist through early next week, generally increasing to 10-20 mph each afternoon with occasional gusts approaching 25-30 mph before gradually easing by midweek.

By Wednesday, some guidance indicates some mid-level vorticity from Invest 91L over the northeastern Gulf may round the periphery of the ridge and move across South Texas. Although the prominent ridge will continue to favor limited precipitation, this energy could support a slight increase in rain chances, primarily in the afternoon along the seabreeze.

AVIATION

(00Z TAFS) Issued at 646 PM CDT Sat Jul 18 2026

Seasonal conditions are expected through this period with MVFR CIGS developing in the overnight periods with VFR conditions during the daytime. Gusty southeasterly winds develop in the late morning east and gradually spread westward into the afternoon west. Winds subside for most sites overnight, though LRD could remain at moderate levels through the period.

MARINE

Issued at 126 PM CDT Sat Jul 18 2026

A moderate (BF 4) onshore flow is forecast for the next several days, with a fresh breeze developing along the coast south of Port Aransas in the afternoons. By midweek next week, overall flow will lower slightly to become more gentle to moderate (BF 3-4). Rain chances through the period will be very low (<10%).
