**Persistent cloud cover, northeast winds, and elevated humidity are moderating overnight cooling across the Chicago area, keeping the minimum temperature on September 17 centered in the mid-to-upper 60s.** Official guidance from sources including WeatherBug and regional forecasts shows a mostly cloudy to overcast night with lows in the mid-60s (around 67–69°F in several runs), consistent with the tightly clustered market probabilities around 64–69°F. Northeast flow off Lake Michigan and a lingering chance of showers or thunderstorms limit radiational cooling that would otherwise allow clearer skies and sharper temperature drops. This setup aligns with the broader late-summer pattern of above-average readings but a gradual seasonal decline, with recent days featuring highs in the low-to-mid 70s and overnight lows holding in the upper 60s. Model consensus supports this range rather than a sharper cool-down or warmer rebound, though minor shifts in cloud timing or wind direction could nudge the exact minimum within the 64–69°F band. Historical averages for September 17 (near 58°F) highlight how the current synoptic conditions are producing warmer-than-normal overnight readings. Traders appear to be pricing in the latest short-range guidance, with the close distribution across 64–69°F reflecting remaining uncertainty in the precise hourly minimum.

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 17 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.**Persistent cloud cover, northeast winds, and elevated humidity are moderating overnight cooling across the Chicago area, keeping the minimum temperature on September 17 centered in the mid-to-upper 60s.** Official guidance from sources including WeatherBug and regional forecasts shows a mostly cloudy to overcast night with lows in the mid-60s (around 67–69°F in several runs), consistent with the tightly clustered market probabilities around 64–69°F.
