Updated at 129 PM CDT Wed Apr 22 2026

- Coastal Flood Advisory is in effect through 7 PM this evening. Minor coastal flooding and moderate to high risk of rip currents remains possible through the week.

- Moderate Heat Risk beginning this weekend for the inland Coastal Plains to the Rio Grande Plains. A major risk may develop across portions of the western areas early next week.

DISCUSSION

Issued at 129 PM CDT Wed Apr 22 2026

Isolated weak showers will remain possible across the Southern Coastal Bend while scattered showers and thunderstorms are expected across the Victoria Crossroads this afternoon. Otherwise, rain chances are expected to end tonight as a mid/upper level ridge builds across the region. Little to no rain is expected through the remainder of the week into the weekend.

With ridging aloft and less cloud cover, temperatures will increase through the period. Highs are expected to approach 100 across the western areas by the weekend and 100-102 by early next week. These temperatures combined with elevated humidity will lead to heat indices 100-105 degrees. Thus, there is a moderate risk of heat related impacts this weekend across the inland Coastal Plains and westward to the Rio Grande Plains. A major heat risk could develop early next week across portions of the Brush Country and Rio Grande Plains.

Minor coastal flooding currently occurring along portions of the gulf facing beaches is expected to recede through late afternoon/evening as we head into low tide. The chance for minor coastal flooding during times of high tide are less certain the remainder of the period. Some models indicate 8 second period swells return by Thursday night which could lead to minor coastal flooding and/or moderate to high risk of rip currents through Friday. The PETSS indicates tide levels to remain above 1.5ft MSL at Aransas Pass during high tide through the weekend. The longer swell periods could provide enough momentum for the water to reach the dunes. Will continue to monitor trends for possible Coastal Flood Advisories through the period.

AVIATION

(18Z TAFS) Issued at 129 PM CDT Wed Apr 22 2026

Expect generally VFR conditions to prevail through this afternoon with brief periods of MVFR. This is due to isolated showers across the southern Coastal Bend to scattered showers and thunderstorms expected across the Victoria Crossroads through the afternoon. The VCT TAF site has the best chance of TSRA's this afternoon and have kept the PROB30 for that reason. Rain chances are expected to diminish tonight with little to no rain chances through the weekend. Drying in the mid/upper levels will result in an environment conducive for fog to develop overnight/early Thursday morning. However, confidence is low that VSBYs will drop to IFR as most models indicate MVFR-VFR VSBYs. This may be due to forecasted wind speeds at or above 4SM. CIGs are more likely to lower to IFR/LIFR overnight. VFR conditions expected by mid to late Thursday morning.

MARINE

Issued at 129 PM CDT Wed Apr 22 2026

A mainly gentle to moderate (BF 3-4) onshore flow will persist through the week and into the weekend. Rain chances end tonight with little to no measurable rain expected through the weekend.

FIRE WEATHER

Issued at 129 PM CDT Wed Apr 22 2026

The chance for wetting rains ends tonight with little to no measurable rain expected through the period. Minimum RH values will remain generally above 30-40%. Temperatures will increase to well above normal. The ERC is expected to remain low along with above normal moisture for fuels. Overall, fire weather concerns are not anticipated at this time.
