Recent Met Office guidance and ensemble models indicate overnight lows in London on September 20 will likely settle between 11–15 °C under clearing skies and light northwesterly winds after a daytime high near 21 °C. Radiational cooling beneath partly clear conditions supports the market’s emphasis on 14 °C (45.5 %) and 15 °C (32.5 %), while 13 °C (20 %) remains viable if winds stay calm. Warmer outcomes above 16 °C carry low probability given the expected advection of cooler maritime air. Updated high-resolution runs and Met Office briefings tomorrow morning represent the final inputs before resolution.

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=eglc
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.
