Current National Weather Service forecasts and ensemble model runs indicate Austin overnight lows on August 27 will settle in the mid-70s, with consensus around 76–78°F driven by persistent southerly flow, high humidity near 60–70%, and partly cloudy skies that limit radiative cooling. Scattered afternoon thunderstorms may increase cloud cover into the evening, moderating the drop while weak winds reduce mixing. Trader consensus clusters tightly around 76–79°F bins because recent model guidance shows minimal spread, though exact resolution hinges on precise timing of any showers and urban heat retention. Historical late-August norms near 73–75°F underscore the elevated baseline from ongoing warm advection.
