KEY MESSAGES

- Moderate risk of heat-related impacts through next week, afternoon heat indices of 100-110

- Hazardous marine conditions through Monday

- Rain-free conditions through this week

DISCUSSION

Issued at 128 PM CDT Sun Jun 21 2026

Moisture and rain chances decrease tonight as a mid-level ridge centered over far West Texas into northern Mexico protrudes itself into South Texas and washes away the wet effect a coastal trough had on us. This ridge will be the dominant feature controlling our weather throughout this entire week, bringing warm, mostly sunny, and rain-free conditions. Temperatures will be relatively steady with highs in the 90s and lows in the mid to upper 70s. Dewpoints in the mid to upper 70s will cause heat indices to range from 100-110 daily in the afternoon, raising heat-related impacts to a moderate risk. Winds will persist out of the south to southeast at a sustained 10-20 mph with lighter winds at night. Although moisture decreases to near or below normal PWATs, can't count out a few showers and thunderstorms with the seabreeze.

AVIATION

(00Z TAFS) Issued at 627 PM CDT Sun Jun 21 2026

A mix of VFR and MVFR conditions for VCT, ALI and CRP, will become predominantly MVFR between 03-06Z. Farther west, COT could briefly see MVFR CIGs around sunrise. LRD may also see brief MVFR CIGs, but is less likely, thus did not include in the TAF. Otherwise, VFR conditions can be expected by mid morning Monday and will continue through Monday afternoon. S-SE winds will relax this evening, then restrengthen Monday morning with gusts 20-25 knots through Monday afternoon.

MARINE

Issued at 128 PM CDT Sun Jun 21 2026

A fresh to occasionally strong south to southeasterly breeze (BF 5-6) is expected through Monday morning, warranting a Small Craft Advisory to be in effect. The Advisory may need to be extended through the afternoon for the bays and nearshores south of Port Aransas. Afterwards, the flow becomes moderate to fresh (BF 4-5) with seas 3-5 feet for the rest of the week.
