Latest forecasts for Wuhan on September 19 show a high near 28°C under partly cloudy conditions with light northerly winds, consistent with multiple model runs including GFS and ECMWF guidance. Current surface observations and short-range models indicate modest daytime heating amid moderate humidity and minimal precipitation risk, keeping the peak temperature centered on 27–29°C. Trader sentiment, reflected in the market distribution favoring 28°C, incorporates this consensus while accounting for inherent uncertainty from variable cloud cover, slight steering pattern shifts, and model spread that could nudge the daily maximum by 1–2°C. Official China Meteorological Administration data and real-time station readings tomorrow will determine the exact outcome.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zhhh
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
