Current National Weather Service and ensemble model guidance indicate Austin's August 28 overnight low will most likely settle in the mid- to upper 70s under partly cloudy skies and light southeast flow, consistent with recent heat-dominated patterns but above the long-term climatological average near 72°F. The elevated 34.5% market-implied odds on 69°F or below reflect residual uncertainty in boundary-layer cooling rates, potential for clearer nocturnal conditions, and minor model spread in dewpoint and wind forecasts that could permit greater radiational cooling. Warmer bins (mid-70s through low-80s) capture the consensus trajectory, while the closely bunched probabilities around 72–81°F underscore the narrow but meaningful range still sensitive to the final evening wind shift and cloud cover.
