Official observations from Chicago Midway International Airport (KMDW), the designated station for this market, recorded a daily maximum of 76–77°F on June 16, 2026, under partly cloudy conditions with limited daytime heating ahead of an approaching frontal boundary. National Weather Service analyses and nearby ASOS data confirmed modest temperatures consistent with climatological norms for mid-June, where average highs hover near 80°F but can fall several degrees under increased cloud cover and onshore flow. Trader consensus reached 100% implied probability once preliminary hourly readings and preliminary climate reports aligned precisely within this narrow band, reflecting high confidence in verified station data over model projections. Only a post-event quality-control revision by NOAA or an undetected sensor anomaly at KMDW could alter the outcome before final certification.

This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 16 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Chicago O'Hare Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/il/chicago/KORD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Official observations from Chicago Midway International Airport (KMDW), the designated station for this market, recorded a daily maximum of 76–77°F on June 16, 2026, under partly cloudy conditions with limited daytime heating ahead of an approaching frontal boundary.
