Forecasts from National Weather Service partners indicate an overnight low in the mid-70s for Austin on August 28 under partly cloudy skies and light southeast winds, with minimal radiational cooling expected amid elevated humidity and residual warmth from daytime highs near 100°F. Southerly flow and limited clear-sky duration cap the diurnal temperature drop, consistent with late-August climatology where typical lows range 74–78°F. Model runs show modest spread tied to exact cloud timing and boundary-layer mixing, producing the observed market dispersion across the 70–79°F bins while the sub-70°F outcome reflects tail-risk scenarios of stronger clearing. Updated guidance and hourly observations will refine the final minimum before resolution.
