National Weather Service guidance and ensemble means from GFS and ECMWF models forecast a tight cluster of high temperatures around 60-65°F at Chicago O'Hare on March 29, driven by mild south-southwesterly flow transporting warmer Gulf-sourced air northward under a neutral-to-weak La Niña pattern that exceeds the late-March climatological average of 52°F. Trader sentiment favors 62-63°F at 28% implied probability due to recent 12z runs showing optimal peak afternoon heating with partial cloud cover, while subtle differences in boundary-layer mixing and lower cloud persistence could cap outcomes at 60-61°F or push toward 64-65°F. Key uncertainties involve evolving cloud trends and exact timing of the daily maximum; watch for 00z model updates later today for potential refinement ahead of resolution.

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.
