This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 30 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent National Weather Service forecasts for Chicago on August 30 highlight a warm front and southwesterly flow advecting milder air, supporting highs near 86°F with 30% early storm chances before partly sunny, breezy conditions. Stronger southwest winds of 15–20 mph with gusts to 30 mph may enhance mixing and limit peak warming, while lingering morning cloud cover from overnight moisture tempers surface heating. Official guidance aligns with mid-to-upper 80s, consistent with trader emphasis on the 84–87°F bins, though model spread in timing of any showers introduces modest uncertainty for exact resolution near the 86–87°F threshold. Historical August 30 averages near 81°F provide context for the above-normal pattern driven by the current synoptic setup.
