Persistent heavy rainfall and extensive cloud cover from a strong low-pressure system are suppressing daytime heating in Tokyo on September 21, keeping maximum temperatures within a narrow 23–26°C range according to official forecasts. Northeast winds and near-100% precipitation probability further limit solar insolation and evaporative cooling effects, moderating peaks below late-September climatological norms of roughly 25–28°C. Japan Meteorological Agency guidance and ensemble model consensus converge on a high near 26°C, aligning with the market’s leading outcomes at 24°C (36%), 23°C (25%), and 25°C (24.5%). Any late-day clearing or slight model shifts could nudge the observed maximum toward the upper end of this band, though sustained rain makes significant warming unlikely.

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=rjtt
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.
