**Trader sentiment centers on official National Weather Service forecasts and model consensus pointing to a daily high in the mid-70s for Chicago on August 23, 2026.** NWS guidance from the Chicago office projects a high near 73°F under sunny skies with northwest winds of 10-15 mph and gusts to 20 mph, moderating temperatures via Lake Michigan's cooling influence. Morning observations around 65-67°F and hourly trends support a peak in the low-to-mid 70s, well below the 82°F climatological normal. Slight upward bias toward 76-77°F (54.5% implied) versus 74-75°F (31.5%) reflects minor model spread, potential urban heat-island effects at certain stations, and real-time updates that could nudge readings higher before sunset. No significant warm advection or cloud cover changes are expected to alter this range, keeping higher bins at low probability.

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 23 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
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.**Trader sentiment centers on official National Weather Service forecasts and model consensus pointing to a daily high in the mid-70s for Chicago on August 23, 2026.** NWS guidance from the Chicago office projects a high near 73°F under sunny skies with northwest winds of 10-15 mph and gusts to 20 mph, moderating temperatures via Lake Michigan's cooling influence.
