National Weather Service forecasts from the Chicago office project a high temperature of 76°F at O'Hare International Airport today under mostly sunny skies with southerly winds enhancing warm air advection, driving the market's 100% implied probability for 54°F or higher. Current observations already show midday readings near 79°F, aligning with model consensus from recent GFS and NAM runs that indicate peak heating this afternoon amid low cloud cover and high pressure dominance. Historical April 21 normals hover around 61°F, making sub-54°F outcomes climatologically improbable without an unforeseen cold front or marine influence, which satellite imagery and upper-air analyses rule out; resolution awaits official daily maximum from NOAA archives.

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 21 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.
