Recent short-range forecast models from the China Meteorological Administration show Wuhan's daily maximum temperature on May 17 settling at 28°C at the Tianhe International Airport station. Light southerly flow beneath a modest subtropical ridge supports daytime warming while partial cloud cover limits further intensification, producing conditions consistent with mid-May climatological norms of 25–30°C highs. Traders have converged on the 28°C outcome at near-100% implied probability because multiple model runs align tightly and historical records show low variance in this range. A sudden increase in insolation or shift in steering patterns could push readings to 29°C or higher, though current guidance indicates minimal likelihood before resolution.

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.
