Trader consensus on Polymarket reflects substantial uncertainty in ensemble forecasts from NOAA's Global Forecast System (GFS) and European Centre for Medium-Range Weather Forecasts (ECMWF) for Chicago O'Hare's highest temperature on April 3, with models diverging between a cold frontal passage yielding 39°F or below amid heavy rain and cloud cover—highlighted by recent NWS alerts for April 3-5 flooding risks—and warmer southerly flow ahead of the system pushing 58°F or higher. Normal highs hover around 54°F per NWS climatology, but transitional spring patterns amplify variability through steering winds and jet stream positioning. Key differentiators include timing of an upper-level trough and precipitation efficiency, with daily 00Z/12Z model updates and NWS Chicago Area Forecast Discussions expected to refine probabilities before resolution based on 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.
