Recent forecasts from the Wuhan Meteorological Observatory and international models indicate a low of 20–22°C on September 4, driven by clear to partly cloudy skies after frontal passage and northerly winds that enhance nocturnal radiative cooling under moderate humidity. Multiple sources, including ECMWF and GFS guidance, converge on this range following scattered rain on September 2–3 that lowered daytime maxima. The market's near-even probabilities across 20–25°C outcomes reflect trader recognition of typical 1–2°C uncertainties in minimum temperature resolution, local site variations, and the short lead time before official verification. Upcoming model runs and the observatory's daily briefing will likely refine these odds.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
