**Forecast models currently indicate a minimum temperature in Austin on August 25 around the mid-70s°F under mostly clear skies and light south-southeast winds, consistent with the market's closely bunched leading outcomes (74–75°F at 33%, 72–73°F at 27%, and 76–77°F at 26.5%).** Persistent high pressure and a strong heat ridge favor strong daytime heating into the low-to-mid 100s, followed by efficient nighttime radiative cooling. However, dew points near 68–70°F and modest boundary-layer mixing from light winds (5–10 mph) will limit how far temperatures fall, keeping the low well above historical extremes for late August. Slight differences among ensemble members in overnight cloud cover or wind gusts create the tight clustering of probabilities around 72–77°F, as even modest increases in humidity or residual cloudiness can raise the minimum by 2–3°F while clearer, calmer conditions allow deeper cooling toward the lower 70s. No major frontal passages or tropical moisture are expected to alter the pattern before the minimum is recorded.
