KEY MESSAGES

- Generally dry with seasonable temperatures (highs mainly in the low to mid 80s and overnight lows mainly in the 50s and 60s).

- Most locations will remain dry, though locations west of the metro area may see isolated to scattered rain/storms mainly on Wednesday.

- Rain chances slightly increase in coverage Friday into the weekend in association with some upper level disturbances passing through Texas.

DISCUSSION

Issued at 1150 PM CDT Mon Oct 26 2026

Broad ridging will persist across the eastern and southeastern CONUS, while persistent troughiness remains positioned to our west. This pattern will continue to bring relatively dry conditions and seasonable temperatures across the region this week.

A weak upper trough will continue to lift northeastward across the Southern and Central Plains overnight/today, resulting primarily in mid to high cloudiness across Southeast TX. Low to mid level moisture increases slightly for areas west of I-45, particularly across our southwestern counties. This could result in isolated to scattered showers/storms, mainly in the afternoon with peak daytime heating through Thursday.

The pattern aloft will become more zonal to southwesterly heading into the end of the week and into the weekend. This will allow a few shortwaves embedded in the flow to move overhead. Depending on the amount of low to mid level moisture available, this pattern could potentially bring chances of rain/storms Friday through Saturday afternoon. At the moment, will continue with a 20-40% chance of rain, centered mainly west of I-45 where forecast models suggest higher moisture content resides.

After a lull in precipitation late Saturday and Sunday, we will continue to monitor the next rain and storm chances likely arriving along and ahead of a cold front early next week. It remains too far out for specific details, so we will keep an eye on its overall evolution in upcoming forecast updates.

AVIATION

(06Z TAF Issuance) Issued at 1150 PM CDT Mon Oct 26 2026

Could see brief patchy fog in spots early Tuesday morning, though chances are low and impacts will be minimal if any. Isolated showers may develop in a few spots west of I-45 on Tuesday, though coverage and chances remain too low to warrant inclusion with this TAF package. Winds become light and variable tonight. VFR conditions continue to dominate throughout current TAF cycle.

MARINE

Issued at 1150 PM CDT Mon Oct 26 2026

A long fetch of easterly flow will persist through most of the week, leading to moderate onshore winds and seas generally 3 to 5 ft. Occasional higher seas are possible offshore at times. Isolated to scattered showers and thunderstorms are possible daily, as different disturbances move through the region. The best chances of rain/storms will be near the Matagorda Bay region and adjacent Gulf waters.

Beach conditions: Will continue to monitor for isolated/minor coastal flooding. P-ETSS guidance suggests water levels around 3.0 ft MLLW, particularly during times of high tide tonight through the rest of the work week.
