Trader consensus on Polymarket reflects tight clustering around 57-59°F (combined ~55% implied probability) for Chicago's April 4 high temperature, aligning closely with the National Weather Service climatological normal of 54.4°F while accounting for a late-March warming trend after regional blizzards and windstorms disrupted patterns through March 17. Ensemble guidance from NOAA's GFS and ECMWF models shows a spread of 50-65°F due to uncertainty in jet stream positioning and potential cold air advection from lingering Great Lakes influences, which often moderate early spring highs via lake breezes and cloud cover. Key differentiators include boundary layer mixing under southwesterly flow versus overcast conditions from any upstream systems; new 12z model runs and NWS updates expected daily will refine probabilities ahead of resolution using official O'Hare observations.

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.
