Latest National Weather Service guidance and GFS/ECMWF ensemble model consensus project Chicago O'Hare's high temperature near 62°F on March 29, fueling trader sentiment clustered around 60-65°F outcomes amid southerly winds advecting warmer air masses under a developing upper-level ridge that promotes subsidence warming and enhanced insolation. This setup exceeds the March 29 climatological normal of 52°F, despite a neutral-to-weak La Niña pattern typically favoring cooler anomalies. Differentiating the closely matched leaders—62-63°F (30%), 60-61°F (21%), 64-65°F (17.5%)—are uncertainties in boundary-layer mixing efficiency and mid-level cloud cover, where clear skies could boost peaks to 64-65°F via stronger vertical mixing, while thin clouds might cap at 60-61°F. Traders eye tonight's 00Z model updates for refinements ahead of peak afternoon heating, with negligible precipitation risk.

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.
