Benign conditions will persist for the rest of today and tonight. Expect partly cloudy skies along with southeast winds at 5-10 mph this afternoon and relaxing to 5 mph or less tonight. The highs this afternoon will peak in the lower 90s for much of the inland portions of Southeast TX and the upper 80s along the coasts. Heat indices will range between the upper 90s to lower 100s. Unfortunately, these heat indices will remain in the upper 90s to lower 100s through at least Tuesday. Thus, make sure to practice heat safety and drink plenty of water, take several breaks from the heat/sun, and wear appropriate clothing if you plan to work or spend time outdoors. The overnight lows for the next few nights will range in the lower to mid 70s inland and the upper 70s to lower 80s along the coasts.

There is a chance for isolated to scattered showers and thunderstorms within and near the seabreeze on Monday afternoon, mainly for areas near and south of I-10. Rain chances decrease Monday night as diurnal heating decreases. Chance for showers and thunderstorms are expected to increase on Tuesday afternoon and evening, as diurnal heating and instability increases. We may also have a few vort maxes moves through the area as well as a boundary that could enhance shower and thunderstorm activity. Thus, there is a good chance we see rain activity occur over areas outside of the seabreeze boundary. On Wednesday, we will once again have afternoon showers and thunderstorms develop as diurnal heating peaks, instability increases, and lingering weak vort maxes push through.

For the end of the work week, rain chances look to continue as an upper level low moves east-northeast from Baja California into Northern Mexico and weak embedded disturbances ahead of it move across Texas. We continue to see the trend of somewhat "cooler" temperatures Thursday and Friday, with highs generally in the upper 80s for both days. Stay tuned for more!

MARINE

Issued at 1248 PM CDT Sun May 31 2026

Light onshore winds and low seas are expected through Tuesday. Winds become east-southeast late Tuesday as a weak boundary moves through. Winds also increase late Wednesday into Thursday and may be moderate at times through the end of the work week, which will lead to seas rising to around 3 feet over the nearshore waters and around 5-6 feet over the offshore waters.

The risk of strong rip current will increase starting on Wednesday over the Gulf facing beaches. Seabreeze showers and storms are expected Monday, followed by daily chance of showers and thunderstorms for the rest of the week.
