Trader consensus on Polymarket reflects tight uncertainty in National Weather Service (NWS) forecasts for Chicago's O'Hare International Airport high temperature on March 29, with ensemble models clustering outcomes between 58-63°F amid mild southerly flow from a departing cold front. The slight edge to 60-61°F (23.5%) stems from the GFS model's warmer bias showing peaks near 62°F under partly cloudy skies, while the cooler European model (21.5% for 58-59°F) factors in persistent low clouds capping daytime heating. Key differentiators include timing of boundary layer mixing, exact cloud cover evolution, and urban heat island effects at O'Hare; historical March averages hover around 45°F, but current climatological analogs favor this above-normal warmth. New hourly guidance expected overnight could sharpen probabilities as resolution nears.

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.
