National Weather Service guidance and ensemble forecasts from NOAA's GFS and ECMWF models have converged on a high temperature near Chicago O'Hare of 60-65°F on April 8, driving the 98% market-implied probability for 50°F or higher as traders price in a strengthening warming trend following April 2 severe thunderstorms. Current upper-air patterns feature a building ridge over the central U.S., promoting warm air advection amid light southerly flow and minimal precipitation risk, aligning with April normals around 56°F. Realistic challenges include an unexpected northward surge of cool Canadian air, persistent cloud cover from upstream systems, or model discrepancies in short-range runs, with new 12Z updates expected daily through 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.
