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 1 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Chicago O'Hare Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader sentiment for Chicago's highest temperature on April 1 at O'Hare International Airport reflects high uncertainty, with market-implied odds favoring 52°F or higher at 32.5% amid a broad distribution peaking in the mid-40s to low 50s, driven by GFS and ECMWF ensemble consensus clustering around 44-51°F—near the 53°F climatological normal. Recent National Weather Service observations show unseasonably warm late March conditions, including 62°F on March 29 under a high-pressure ridge, but an approaching upper-level trough and cold front signal potential cooldown via cold air advection and cloud cover, risking sub-45°F highs if the system accelerates. Key variables tipping outcomes include trough timing, jet stream position, and boundary layer mixing; daily NOAA model runs and NWS updates through April 1 will refine probabilities as resolution nears.
