DISCUSSION

Issued at 329 PM CDT Fri May 1 2026

A marginal risk for severe thunderstorms remains in effect through tomorrow morning. There's also a marginal to slight risk of excessive rainfall through the same time frame. Primary areas affected is expected to be the northern Coastal Bend and Victoria Crossroads.

A cold front is pushing through South Texas today, accompanied by a mid-level trough and moisture converge. This setup is producing scattered to widespread showers and thunderstorms, with gusty winds, large hail (~1.0-1.25"), periods of heavy rainfall and localized flooding possible. Generally guidance supports rainfall totals 0.25- 1.0 inch with isolated higher amounts. Behind the front, cooler and drier conditions filters into the region tonight, along with gusty winds. A Wind Advisory is in effect from 7 PM through Saturday morning along the Coastal Bend and barrier island where strong north to northeasterly winds 20 to 30 mph with gusts up to 40 mph are expected. Frequent gusts to gale force expected across the marine zones, so a Gale Warning remains in effect for this evening through Saturday morning. Overnight temperatures tonight fall into the mid 50s inland to upper 60s along the coast.

Minor coastal flooding is possible behind the cold front tonight into Saturday during high tide as strong northeasterly flow develops over the gulf waters, seas build to 10-13 ft, and swell periods increase to around 8 seconds. A moderate rip current risk remains for today through Saturday, but the potential remains that we will need to increase this to a high risk.

On Saturday, subsidence aloft and a surface high will promote clearing skies and kick off a warming trend as onshore flow returns early in the week. Mid 90s return to the forecast for a couple of days around mid-week

AVIATION

(00Z TAFS) Issued at 611 PM CDT Fri May 1 2026

Showers and thunderstorms will continue to move east across South Texas for the next 2-3 hours. MVFR ceilings are expected to linger across the north and east through tonight, though a few sites have already started to see some VFR across the west. Expect ceilings to gradually increase after sunrise and return to VFR by midday Saturday. North to northeasterly wind gusts as high as 30 knots are possible through Saturday morning.

MARINE

Issued at 329 PM CDT Fri May 1 2026

A cold front will increase flow slightly to a more moderate to fresh flow today before shifting to the northeast this evening and then increasing to strong to near gale (BF 6-7) tonight through Saturday. A Gale Warning remains in effect this evening through Saturday morning. Winds will gradually diminish to a moderate to fresh (BF 4- 5) Saturday night through Sunday before further weakening to gentle to moderate flow and turning east to southeast. There's a medium to high (30-70%) chance of showers and thunderstorms the rest of today and tonight will diminish from northwest to southeast Saturday.
