Official observations from National Weather Service stations, including Chicago Midway International Airport, recorded a daytime high in the low-to-mid 70s°F on June 2 under partly cloudy skies and moderate northeast flow, placing the outcome comfortably above the 70°F threshold. This outcome aligned with June climatological normals near 76°F and ensemble model guidance that consistently favored temperatures well into the 70s without significant cool-air advection or persistent cloud cover. Trader consensus at 100% for 70°F or higher reflects the strong observational consensus and limited uncertainty in post-event verification, though minor station-to-station variations in final reported maxima remain the only realistic pathway for any adjustment.
