KEY MESSAGES

Issued at 609 AM CDT Sun Oct 25 2026

- Mostly dry conditions expected into the beginning of the work week, with isolated showers possible.

- Low to moderate rain chances return Monday night through Tuesday.

- Minor coastal flooding becomes increasingly possible late this weekend into midweek.

DISCUSSION

Issued at 142 AM CDT Sun Oct 25 2026

Upper-level ridging will gradually shift eastward through midweek as a low pressure system lifts northeastward from the Desert Southwest into the Great Basin. Increasing southwesterly flow aloft will allow disturbances to move across South Texas combined with moisture from the Gulf, supporting a wetter pattern beginning Monday.

While PWATs briefly decrease to below the 50th percentile Sunday night, moisture will rapidly recover Monday into Tuesday, with ensemble guidance suggesting values approaching 1.7 - 1.9" or higher. Rain chances will increase Monday night and continue through much of Tuesday, with locally heavy rainfall possible. Most locations should receive around one-half inch, although isolated totals of 1-2 inches cannot be ruled out.

Temperatures will generally range in the 80s, but increase next weekend with the Brush Country returning to the low 90s. Overnight lows will range in the 60s across most locations increasing to around 70 degrees by the end of the forecast period.

Minor coastal flooding remains a concern through at least mid-week as increasing swell periods and elevated tides coincide with the upcoming full moon. Water levels may approach 1.8-1.9 feet above MSL during high tides during this time.

AVIATION

(12Z TAFS) Issued at 609 AM CDT Sun Oct 25 2026

Mainly VFR conditions through the TAF cycle with CIGs remaining above 4,000ft. There is a low chance of showers this morning across CRP and in the afternoon across ALI. Brief MVFR conditions may accompany the showers, but should have minimal to no aviation impacts. Most of S TX will remain dry. Light and variable winds this morning will increase from the east-southeast to 10-15 knots with gusts 20-25 knots. Light and variable winds expected tonight.

MARINE

Issued at 142 AM CDT Sun Oct 25 2026

Moderate onshore flow (BF 4) will occasionally increase to fresh levels (BF 5) through Monday, with seas generally 3-4 feet. Seas may briefly build to 5-6 feet Monday night before gradually subsiding by Tuesday night. Rain chances increase Monday and Tuesday, with scattered to numerous showers and thunderstorms possible.

FIRE WEATHER

Issued at 142 AM CDT Sun Oct 25 2026

Elevated fire weather conditions are not anticipated through the period. Minimum RH values above 30%, along with increasing moisture and rainfall chances early in the week, will limit fire weather concerns. Widespread wetting rainfall is possible Tuesday, particularly across the eastern portions of South Texas.
