KEY MESSAGES

Updated at 545 AM CDT Mon Aug 31 2026

- Hot and mostly dry weather continues Monday.

- Increased chances for showers and storms Tuesday through Friday over the Coastal Plains associated with multiple disturbances over the Gulf.

SHORT TERM

(Today through Tuesday) Issued at 132 AM CDT Mon Aug 31 2026

Monday will feature hot and dry weather across South Central Texas with high temperatures in the upper 90s for most locations, while the Rio Grande Plains climb into the 100-104 range. Subtropical ridging slowly slides into northern Arkansas Monday afternoon, and underneath the high, Invest 97L will move westward. At this time, most consensus model runs take it into southeast Texas as a weak tropical storm sometime early Tuesday morning. Minimal impacts are expected locally, with virtually no impacts along the I-35 Corridor and westward. Expect continued hot and dry weather through Tuesday for locations outside of the Coastal Plains.

LONG TERM

(Tuesday night through Sunday) Issued at 132 AM CDT Mon Aug 31 2026

Increased moisture from this system will result in scattered showers and storms for the Coastal Plains Tuesday afternoon/evening and stretching into the day Wednesday. While we will carry PoPs for the Austin metro, the greater chance for showers and storms will be over the Coastal Plains through Friday morning. A second tropical wave may move into South Central Texas Thursday/Friday, but for now, confidence is quite low. Despite any tropical disturbances, the heat and humidity will continue and highs will easily climb into the upper 90s to around 100 most days through the remainder of the forecast period. One positive thing to note is that we may finally break free of persistent ridging by next weekend as the pattern breaks down.

AVIATION

(12Z TAFS) Issued at 545 AM CDT Mon Aug 31 2026

Low clouds and MVFR cigs will continue along the I-35 corridor through early morning. Cigs should lift and scatter back to VFR by mid morning or roughly 16Z, with VFR through the remainder of today. Winds remain from the east and southeast through most of the period. Low cloud development is likely again Tuesday morning.
