DISCUSSION

Issued at 118 AM CDT Wed Oct 28 2026

Low to medium rain chances will continue over the Coastal Plains today as another shortwave moves across the area. By Thursday, the remnants of Pacific Tropical Storm Vance will move into South Texas, with the highest moisture along the Rio Grande. This will shift medium rain chances over the Brush Country and Rio Grande Plains. WPC has placed the Brush Country under a Marginal Risk (level 1 out of 4) of excessive rainfall Thursday, with a Slight Risk (level 2 out of 4) extending into northwestern portions of the region. Locally heavy rainfall and isolated flash flooding will be possible, especially where storms become persistent or training develops. Isolated flooding and ponding will be possible in low lying poor drainage areas. However, uncertainty remains regarding the location and magnitude of the heaviest rainfall. Rain chances will diminish to low Friday into the weekend as the remnants move to the northeast. Fortunately, rain chances look like they will be out of the area by the evening Saturday night and we will remain dry through the rest of the weekend.

Another cold front is possible Tuesday, which could increase our rain chances once again. For now, we will continue to focus on the beneficial rain this week.

Minor coastal flooding remains a concern through much of the week as persistent onshore flow, elevated swell periods, and astronomical tides contribute to higher water levels during high tide. An increased risk of rip currents will also persist.

AVIATION

(06Z TAFS) Issued at 118 AM CDT Wed Oct 28 2026

There is a low to medium chance of mainly showers with a few storms, along with patchy fog, developing after 08Z across the ALI, CRP and VCT TAF sites leading to periods of IFR/MVFR conditions throughout Wednesday afternoon. The chance of showers shifts to the west to LRD and COT Wednesday afternoon and evening. Outside of the convection, VFR CIGs/VSBYs can be expected. Winds will be light varying between northeast and east through Wednesday morning, becoming east-southeast at 5-15 knots Wednesday afternoon.

MARINE

Issued at 118 AM CDT Wed Oct 28 2026

Gentle to moderate (BF 3-4) southeasterly flow will persist through much of the week, with seas generally 3 to 5 feet, occasionally reaching 6-7 feet offshore early Tuesday. Medium to high rain chances are expected through Wednesday, with lower chances Thursday and Friday. Locally higher winds and seas will be possible near thunderstorms.

FIRE WEATHER

Issued at 118 AM CDT Wed Oct 28 2026

Abundant low-level moisture and winds generally below 20 knots will limit fire weather concerns through the forecast period. Showers and thunderstorms through the work week will continue to limit fire weather concerns.
