**Official observations from Chicago O’Hare International Airport confirm a maximum temperature of 81°F on August 29, 2026, reached at 2:59 PM CDT.** This value exactly matched the 1991–2020 climate normal high of 81°F and aligned with pre-event forecasts calling for highs in the lower to mid-80s under partly cloudy skies with light southwesterly flow. National Weather Service climatological reports and hourly surface data show no readings above 81°F and a minimum of 65°F, producing a daily average near 73°F. With the date concluded and authoritative station data released, trader consensus converged on the 80–81°F outcome at full implied probability. Only unresolved discrepancies between primary reporting stations or post-hoc data revisions could alter resolution, though such adjustments remain rare once the NWS CLI summary is issued.
