Current National Weather Service guidance and ensemble model consensus point to a Thursday high in the mid to upper 70s for Chicago, driven by northerly flow behind Wednesday’s frontal passage that advects cooler, drier air into the region. This setup limits daytime heating despite expected clearing skies, with Lake Michigan’s moderating influence and modest wind speeds further capping peaks near or slightly below the 78°F climatological average. Trader emphasis on the 76–79°F bins reflects uncertainty in exact clearing timing and boundary-layer mixing, while lower-probability warmer outcomes would require stronger southerly return flow or delayed frontal timing. Updated NWS point forecasts and 00Z/12Z model runs over the next 24–48 hours will refine these temperature thresholds ahead of market resolution.

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.
