Persistent rain from a stalled frontal system and northerly winds are cooling Tokyo, with official forecasts pointing to an overnight low near 20–21°C as clouds and precipitation limit radiative cooling while advection of cooler maritime air dominates. Recent observations show daily minima falling from 22°C on September 8 to around 19–20°C in preceding days amid heavy rainfall totals exceeding 70 mm in places. Model consensus from the Japan Meteorological Agency and global ensembles clusters the September 9 minimum in the 20–22°C range, with minor spreads arising from exact timing of wind shifts and rainfall intensity. Traders assign the highest implied probabilities to 21°C and 22°C because these align with the most probable outcomes under current steering patterns and moisture profiles, while the modest probability on 19°C or below reflects residual uncertainty in maximum cooling if showers intensify overnight. Updated model runs and surface observations through the evening will refine the final reading.

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=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.
