KEY MESSAGES

Updated at 137 PM CDT Mon Jun 1 2026

- Isolated to scattered afternoon showers/thunderstorms possible each day with moderate (~50%) rain chances Tuesday and 50-75% towards the end of the week.

DISCUSSION

Issued at 137 PM CDT Mon Jun 1 2026

A broad subtropical ridge will remain the dominant synoptic feature across the Southern Plains through much of the forecast period. While the ridge will support general warm and humid conditions across South Texas, occasional weak disturbance moving around its periphery combined with abundant low-level moisture will maintain at least low-end precipitation chances each day.

A few shortwaves are expected to increase chances for precipitation (40-65%) across much of the region from mid-week into the weekend. The primary focus for convective development will be the afternoon sea breeze and any residual outflow boundaries. Scattered cu development is expected by late morning, with isolated to scattered showers and thunderstorms developing during the afternoon and early evening hours with better coverage across the Coastal Plains and Victoria Crossroads. Any storms that develop will be capable of brief heavy rainfall, gusty winds, and frequent lightning. Consequently, due to the amount of moisture progged to be present later this week, the Weather Prediction Center (WPC) has placed portions of South Texas in a Marginal Risk (level 1 of 4) for Excessive rainfall Thursday and Friday mainly across the Brush Country, Northern Plains and the Victoria Crossroads.

Temperatures will remain near to slightly above normal through the weekend. Afternoon highs are expected to reach the lo to mid 90s across much of the region, with mid- to upper 80s along and near the immediate coast. Combined with persistent Gulf moisture, heat index values will generally range from 100 to localized spots up to 105 degrees during the afternoon hours each day. Warm overnight temperatures are expected with lows generally in the mid to upper 70s.

AVIATION

(18Z TAFS) Issued at 137 PM CDT Mon Jun 1 2026

Currently have VFR conditions this afternoon across all terminals despite some isolated showers along the Coastal Bend. Low end chances for showers expected throughout the afternoon into evening hours. MVFR to VFR conditions are expected overnight tonight into tomorrow morning with VFR conditions expected toward the end of the current TAF period. There's some lower probabilities for IFR CIGs as well. Winds are expected to remain light and variable.

MARINE

Issued at 137 PM CDT Mon Jun 1 2026

Generally, a gentle to moderate (BF 3-4) onshore flow will persist through the period as high pressure remains over the Gulf. There's low chances for showers and thunderstorms over the bays and Gulf waters each day, primarily during the overnight and morning hours and again along the seabreeze; with chances becoming moderate briefly this weekend.
