Trader consensus heavily favors a 70-71°F overnight low for Chicago on September 9, 2026, driven by National Weather Service observations at O’Hare showing a minimum of 71°F at 7:06 a.m. amid persistent mild conditions. Above-normal warmth, with a daytime maximum of 80°F and elevated dew points near 70°F, limited radiational cooling under mostly cloudy skies and light winds. This aligned with late-summer patterns where southerly flow and high humidity suppressed typical September nocturnal drops toward the 60°F climatological baseline. Model consensus prior to the date had consistently projected minimums in the upper 60s to low 70s, with minimal downside risk from cold advection, keeping probabilities for 67°F or below near 1%. Final data releases from NWS climatological reports reinforced this outcome range.

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.
