KEY MESSAGES

Issued at 519 PM CDT Mon Oct 19 2026

- Temperatures gradually warm to above normal by middle of the week.

- Low to very low rain chances through Wednesday across South Texas. Higher chances across the coastal waters south of Port Aransas.

- Minor coastal flooding will remain possible through the week.

- Moderate Rip Current Risk through Tuesday.

DISCUSSION

Issued at 143 PM CDT Mon Oct 19 2026

Temperatures will gradually warm to above normal temperatures by the middle of this week due to a mid/upper level ridge of high pressure and a modifying airmass.

Deep mid and upper level moisture associated with a shortwave moving across South Texas will continue to bring a very low chance of light rain through early tonight. Chances for rain will increase along the coast and over the waters as a surface trough develops, streaming low level moisture into the area Wednesday. As the trough shifts to the west, low rain chances will slide west over the southern Coastal Plains. High pressure will then become more dominate late this week, reducing rain chances to nearly zero through the weekend.

Northeast to east winds are expected to continue through Thursday. Even with winds only 5-15 knots, the persistent direction and swell periods around 8 seconds could lead to minor coastal flooding during times of high tide. As mentioned previously, guidance does keep tide levels below the 2 ft MSL threshold, but will continue to monitor conditions.

Although the northeast flow tends to limit the rip current risk to a low risk, the 8 second period swells makes it hard to go with a low risk. Have left the moderate rip current risk as moderate through Tuesday.

AVIATION

(00Z TAFS) Issued at 519 PM CDT Mon Oct 19 2026

VFR conditions expected to remain through the TAF period with light northeast to east winds across all terminals. There is a small chance for isolated showers that could come up from the coastline to the inland terminals, but not enough confidence to include in TAFs.

MARINE

Issued at 143 PM CDT Mon Oct 19 2026

A moderate to occasionally fresh (BF 4-5) northeast to east breeze can be expected through the mid-week. Low to medium chance of showers will continue through Wednesday.

FIRE WEATHER

Issued at 143 PM CDT Mon Oct 19 2026

Increasing relative humidity values, light winds, and ERC values below the 75th percentile will continue to limit fire weather conditions through the work week.
