Official observations from the National Weather Service at Atlanta's primary airport station recorded a minimum temperature of 58–59°F during the early morning hours of October 12, 2026, under clear skies, light northwest winds, and radiational cooling after a daytime high near 70–76°F. This aligned closely with climatological norms for the date (average low around 56°F) and recent model consensus from the GFS, which had forecasted overnight lows in the upper 50s with minimal cloud cover or moisture to moderate temperatures. Trader consensus at 100% for the 58–59°F bin reflects high confidence in these verified surface measurements. A realistic challenge would require an undetected sensor malfunction, revised post-analysis adjustment by NWS, or use of an alternate station with meaningfully different readings, though such outcomes remain improbable given standard quality controls.
