KEY MESSAGES

Issued at 556 AM CDT Sat Aug 29 2026

- Morning rain chances along the coast then inland in the afternoon

- Warm temperatures and increased HeatRisk through the upcoming week

DISCUSSION

Issued at 122 AM CDT Sat Aug 29 2026

The ever-present mid-level high pressure system slides off to the east this weekend. At the same time, a mid-level open wave on the southern periphery of this high will slowly graze the central Gulf coast as it moves onshore. This increased relative vorticity maxima will enhance the seabreeze more so for locations east of the upper Texas coast. Aside from the morning rain chances along the Coastal Bend this morning and then the afternoon seabreeze convection further inland, the seabreeze won't be as active as it has been the last few days as our upper-level disturbances move away.

Given the lack of much upper-level pattern change, temperatures this week look very similar each day with minimal rain chances. Moderate to Major HeatRisk will be in play each afternoon, with the Brush Country seeing peaks of Extreme HeatRisk, though not enough to warrant any heat-related headlines at the moment.

AVIATION

(12Z TAFS) Issued at 556 AM CDT Sat Aug 29 2026

VFR conditions are expected to prevail, though periods of MVFR conditions are possible this morning for ALI and VCT. A few showers will develop along the coast, then inland later this afternoon.

MARINE

Issued at 122 AM CDT Sat Aug 29 2026

Light to gentle onshore breezes through the week will continue with afternoons reaching more moderate strength for inland bays and waterways and generally 1-2 ft seas. 20% chances of daily morning streamer showers are forecast through the upcoming week.

FIRE WEATHER

Issued at 122 AM CDT Sat Aug 29 2026

Minimum relative humidity values will drop to near 30% each afternoon. Dry and hot conditions over the last month have resulted in Energy Release Component forecast values to hover near the 80th percentile leading to an elevated fire risk, but weak winds will limit the spreading of any fire that develops, though overnight winds will increase to 15-20 mph in the upcoming week across the Brush Country. Chances for rain will be limited to just this afternoon (less than 20%) and then remaining dry through the upcoming week.
