**National Weather Service forecasts project a daytime high near 68°F at Chicago O'Hare International Airport on April 28, 2026, under breezy southwesterly winds and partly cloudy skies, driving the market's 100% implied probability for 56°F or higher as the dominant outcome.** This positioning aligns with the latest model consensus from NOAA's Global Forecast System and European Centre for Medium-Range Weather Forecasts, showing above-normal temperatures continuing a recent warm spell with prior days reaching the low 80s, well exceeding the April 28 climatological normal of 64°F. Trader sentiment reflects strong confidence in persistent high-pressure ridging over the Midwest. Realistic challenges include an unexpected shift in the upper-level pattern introducing cooler air from the north, increased low-level clouds from Lake Michigan, or a stalled frontal boundary causing prolonged overcast conditions, though current ensemble guidance shows low likelihood before evening observations finalize the official high, typically reported from Chicago Midway Airport.**

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 28 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.**National Weather Service forecasts project a daytime high near 68°F at Chicago O'Hare International Airport on April 28, 2026, under breezy southwesterly winds and partly cloudy skies, driving the market's 100% implied probability for 56°F or higher as the dominant outcome.** This positioning aligns with the latest model consensus from NOAA's Global Forecast System and European Centre for Medium-Range Weather Forecasts, showing above-normal temperatures continuing a recent warm spell with prior days reaching the low 80s, well exceeding the April 28 climatological normal of 64°F. Trader sentiment reflects strong confidence in persistent high-pressure ridging over the Midwest.
