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 29 Mar '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 consensus on Polymarket reflects the latest National Weather Service forecast pinning Chicago's March 29 high at 62°F under partly sunny skies, driving the 62-63°F outcome to 22% implied probability amid a tight cluster of 60-67°F bins totaling over 70%. This positioning stems from recent GFS and ECMWF model runs converging on mid-60s peaks after earlier cooler outlooks, influenced by a building high-pressure ridge aloft promoting diurnal heating but with lingering low-level clouds introducing variability. Ensemble spreads of 4-6°F highlight uncertainty in exact peak timing and insolation, common for transitional spring patterns well above the 45°F climatological average. Watch the 12Z model updates and afternoon soundings for potential refinements before resolution.
