Current National Weather Service and model guidance points to a Tuesday overnight low near 68°F in Chicago amid a warm, humid air mass advected by southwesterly flow ahead of a weak frontal passage. Persistent cloud cover and scattered showers will limit radiational cooling, keeping minimum temperatures from dropping toward seasonal norms around 59°F, while any earlier clearing or a faster wind shift could allow readings in the mid-60s. The spread across 59–78°F outcomes reflects uncertainty in exact timing of the front and boundary-layer moisture, with updated evening model runs and local observations likely to narrow the range before market resolution.

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.
