Recent National Weather Service forecasts from the Chicago office indicate a Tuesday high near 64°F for the city, with partly sunny skies, persistent northeast breezes of 15-20 mph, and morning lows in the mid-50s, consistent with model consensus favoring 62-64°F. This places the 62-63°F and 64-65°F bins as the leading market outcomes at 47.5% and 19.0% implied probability, respectively, as traders incorporate the latest guidance showing cooler-than-average conditions driven by onshore flow off Lake Michigan. The 60-61°F range at 30.5% reflects residual uncertainty from variable cloud cover and exact peak timing, while historical September 22 averages near 73.5°F underscore the anomalous cool pattern currently priced in. Updated NWS briefings ahead of market close will likely refine these odds.

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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
