Recent numerical weather prediction models from major agencies converge on a maximum temperature of 28–29 °C for Wuhan on May 17, supported by light southerly flow, partly cloudy skies, and only a modest risk of afternoon showers that could limit surface heating. These conditions align with typical late-spring climatology for the region, where diurnal warming is moderated by humidity and variable cloud cover rather than strong advection or clear-sky insolation. Trader consensus reflected in the closely matched 28 °C and 29 °C probabilities captures the narrow uncertainty band between model runs, with lower-probability outcomes for 30 °C or higher requiring stronger subsidence or reduced cloudiness that current guidance does not support. Updated short-range forecasts issued overnight will provide the final observational benchmark for market 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.
