Trader consensus on Polymarket tilts toward a high of 40-41°F in Chicago on March 27 (24.5% implied probability), edging out 42-43°F (19.5%), as latest NOAA and ECMWF ensemble forecasts converge on mild conditions from a weakening high-pressure ridge over the Midwest, with mean projections around 41°F. Key differentiators include uncertainty in shortwave trough timing, which could suppress peaks below 40°F (17.5% for 36-37°F) if a northern stream jet dip accelerates, versus warmer advection boosting 44°F+ (8.6%) under ridge amplification. Historical March 27 highs average 45°F but vary ±10°F due to Lake Michigan moderation; upcoming 12Z GFS/ECMWF runs will sharpen odds as model spread narrows post-48-hour mark.

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.
