Latest ensemble forecasts from global models like ECMWF and GFS show Wuhan's March 22 high temperature clustering around 20°C, driving the tight race among 18–23°C outcomes with implied probabilities over 25% each. Divergent model runs—GFS projecting peaks near 23°C under southerly winds and clear skies maximizing solar insolation, versus ECMWF's cooler 18–19°C amid lingering cloud cover from a recent frontal passage—explain the spread, compounded by Wuhan's typical late-March diurnal range of 8–10°C. China Meteorological Administration's update pegs 21°C, aligning with a mild warming trend above the 17°C historical average, though diel variability and urban heat effects could tip traders toward higher readings if sunshine dominates.

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 Wuhan Tianhe International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/wuhan/ZHHH.
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 Celsius (eg, 9°C). 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.
