Official National Weather Service observations from Chicago O'Hare International Airport (KORD), the market's authoritative station, confirm a maximum temperature of 63°F on April 18, 2026, at 12:12 AM local standard time, aligning precisely with the 62-63°F outcome commanding 100% market-implied probability. Persistent rain, light rain, and fog—coupled with an advancing upper-level trough ushering cooler mid-level air—suppressed highs well below the prior day's near-73°F peak and the 60°F climatological normal, as detailed in the NWS Chicago daily climatological report. This trader consensus, backed by real capital, reflects verified measurements from automated surface observing systems. Realistic challenges are minimal but could include rare post-preliminary data revisions or instrumentation anomalies, though historical precedents show such adjustments seldom exceed 1-2°F.
