**Trader consensus strongly favors a 60-61°F low for Chicago on September 11, 2026, at 98.5% implied probability, aligning closely with the 1991–2020 climatological average low of 60.7°F.** Official National Weather Service observations and model consensus from the prior week showed typical early-September overnight radiative cooling under mostly clear skies and light southerly flow, producing minimums in the low 60s without significant cold-air advection or cloud cover to alter the outcome. Historical analogs from recent Septembers (lows of 59–67°F) and the absence of anomalous synoptic patterns reinforced this narrow range. Scenarios that could realistically shift resolution include station-specific measurement differences between O’Hare and Midway or revisions in final quality-controlled data, though current evidence indicates low uncertainty around the market-favored bin.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 11 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.**Trader consensus strongly favors a 60-61°F low for Chicago on September 11, 2026, at 98.5% implied probability, aligning closely with the 1991–2020 climatological average low of 60.7°F.**
