Official National Weather Service observations and forecast models for Austin on September 10 showed overnight lows stabilizing near 74–75°F amid clear skies, light southerly flow, and typical late-summer humidity patterns that limited radiational cooling. This aligns with the market's strong consensus on that range, reflecting trader assessment of verified station data from Austin Bergstrom and surrounding sites rather than broader seasonal averages near 70°F. Key resolution factors include precise minimum readings over the 24-hour period ending at midnight. Uncertainties in microclimate effects or minor forecast revisions from updated model runs could still influence final verification, though current evidence supports the dominant positioning.
