The National Weather Service's latest guidance for Chicago O'Hare forecasts a high near 62°F on March 29 under partly sunny skies with southwesterly winds around 10 mph, anchoring trader sentiment in the 60-65°F range where probabilities cluster tightly at 20.5-25.5%. This reflects model consensus from recent GFS and ECMWF runs showing ensemble means in the low-to-mid 60s, driven by ridging aloft advecting mild air after a cooler March 28 high near 49°F, amid neutral-to-weak La Niña conditions exceeding the late-March climatological average of 48°F. Differentiating factors include subtle variations in diurnal boundary layer heating, transient cloud cover, and peak insolation timing, which introduce 2-3°F uncertainty typical of spring short-range forecasts. Watch for 00Z/12Z model updates and morning soundings before resolution on official O'Hare observations.

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.
