National Weather Service observations from Chicago O'Hare International Airport, the official recording site, confirm the high temperature reached 58°F on May 13, driving trader consensus to a 99.9% implied probability for the 58-59°F outcome amid persistent overcast skies and light rain that capped daytime heating. Cooler-than-normal conditions—versus the mid-May historical average of 69.5°F—stemmed from a recent cold front ushering northerly winds and Lake Michigan moderation, with hourly data peaking midday before stabilizing near 57°F daytime average. While market resolution hinges on final verified measurements, realistic challenges like minor instrument recalibrations or data audits could shift it by 1°F, though preliminary reports show strong alignment; expect the daily climatological summary within 24 hours for closure.
