Latest National Weather Service guidance and ensemble forecasts from GFS and ECMWF models drive trader consensus toward Chicago's March 24 high temperature clustering in the 52-56°F range, with 56°F or higher edging out at 30.5% implied probability amid southerly wind influences and partial solar heating potential. Closely trailing 52-53°F (27.5%) and 54-55°F (26.5%) reflect model spread from boundary layer variability and possible mid-afternoon cloud cover, differentiating outcomes via convective mixing efficiency and cold front timing—warmer runs assume stronger warm-air advection, cooler ones persistent stratocumulus decks. Historical late-March norms near 45°F highlight the mild tilt, but 18z updates tomorrow could pivot odds on refined jet stream positioning.

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.
