Trader sentiment on Chicago's highest temperature March 23 remains tightly split between 42-43°F and 44-45°F at 25.5% each, driven by divergent ensemble forecasts from NOAA's GFS (favoring 42-43°F) and ECMWF models (edging toward 44-45°F), amid a weak cold front's uncertain timing. National Weather Service guidance projects a high near 43°F under partly cloudy skies with light northwest winds capping adiabatic warming, while historical March 23 norms average 42°F but vary ±5°F due to lake-effect moderation. Lower odds for 40-41°F reflect fading chances of thicker cloud cover, with upcoming 12z model runs likely to sharpen resolution as surface observations confirm dew points near freezing.

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.
