Recent National Weather Service forecasts for Chicago indicate a Saturday low near 65–67°F amid showers and a southeasterly flow, well above the 1991–2020 average of 57°F, yet trader odds remain split between sub-55°F and 74°F+ outcomes because model runs still differ on the timing and strength of an approaching cold front. Key variables include the depth of post-frontal cooling, boundary-layer mixing, and Lake Michigan’s moderating influence on overnight temperatures, which can shift the minimum by several degrees depending on wind direction and cloud cover. With resolution only two days away, updated NWS model guidance and evening soundings will likely tighten the distribution around the current consensus range.

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 19 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.Recent National Weather Service forecasts for Chicago indicate a Saturday low near 65–67°F amid showers and a southeasterly flow, well above the 1991–2020 average of 57°F, yet trader odds remain split between sub-55°F and 74°F+ outcomes because model runs still differ on the timing and strength of an approaching cold front.
