Current National Weather Service forecasts for Chicago on August 20 point to a high in the upper 70s, below the 82°F August normal, as the main driver positioning 78–79°F and 80–81°F as the leading market outcomes with combined implied probability near 77%. Cooler-than-normal conditions stem from a persistent trough and associated cloud cover limiting daytime heating, consistent with recent model consensus from the National Weather Service and private providers. Updated runs in the past 48 hours have held steady on this range, though any late-day clearing could push readings toward the low 80s; traders appear to weigh these variables against historical variability in late-summer patterns.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 20 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Chicago O'Hare Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/il/chicago/KORD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
