This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 15 Apr '26. 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.Latest National Weather Service forecasts for Chicago O'Hare International Airport, the market's resolution station, project highs near 80°F this afternoon under mostly sunny skies with southwesterly winds at 10-15 mph, propelling the 54.5% implied probability for 74°F or higher as traders weigh strong diurnal heating from a deep warm air mass and persistent upper-level ridge over the Midwest. This builds on recent developments, including yesterday's (April 14) highs in the upper 70s°F and weekend peaks of 81°F tying 2026's warmest readings, consistent with NOAA's warmer-than-average spring outlook amid reduced cold air intrusions. A 20-30% chance of scattered showers and thunderstorms after 3pm introduces uncertainty, bolstering 25% odds for 72-73°F if clouds limit peak heating around 2-4pm; lower outcomes reflect minimal cool-front risk. Monitor hourly observations for resolution.
