Recent forecast consensus from the Japan Meteorological Agency and global models points to a transition toward cloudy conditions with frequent scattered showers and thunderstorms on September 15, limiting solar insolation and daytime heating after a hotter Monday. This frontal influence, combined with elevated humidity near 80-90% and moderate southerly winds, supports maximum temperatures clustered around 25-28°C. Model differences in the timing and coverage of precipitation explain the tight market spread: earlier or heavier rain would suppress the high nearer 25°C, while any afternoon breaks in cloud cover could allow brief warming toward 28°C. Historical September baselines near 27°C provide context, though the active pattern introduces typical forecast uncertainty in exact peak readings.

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.
