Recent National Weather Service forecast models and ensemble guidance project a strong southerly airflow advecting warmer air into the Chicago region, supporting a daily maximum in the upper 70s to low 80s on May 18. This pattern aligns with observed warming trends over the past week and exceeds the mid-May climatological normal of 71°F at O’Hare, driven by reduced cloud cover and enhanced solar heating. The market’s 92% implied probability for 78°F or higher reflects trader confidence in this consensus, tempered by typical forecast uncertainty ranges of several degrees. A faster-moving cold front or unexpected increase in boundary-layer moisture could cap temperatures below the threshold, while any delay in frontal passage would reinforce the warm outcome. Final model runs and NWS updates on May 17 will provide the last major data inputs before resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Chicago O'Hare Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
