**Mild overnight conditions under light southwesterly flow and partial cloud cover are positioning 18°C as the market favorite for London’s minimum temperature on September 14.** Forecasts from the Met Office and multiple global models consistently show overnight lows of 16–18°C, with the tightest clustering around 17°C before dawn, supporting the 53% implied probability for exactly 18°C. Recent guidance highlights a warm, humid airmass with dew points near 16–17°C limiting radiative cooling, while light winds (under 10 mph) prevent stronger mixing that could raise the minimum further. The 22.5% chance for 19°C reflects the small risk of slightly higher readings if cloud cover thickens or winds remain elevated, whereas the 12.5% on 17°C and lower probabilities for 16°C or below align with scenarios of clearer skies and more efficient cooling. No significant frontal systems or temperature advection changes are expected in the next 24 hours, keeping the distribution narrow around the 17–18°C range typical for mid-September in the London basin. Updated model runs and official briefings later today will provide the final data points before market 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.
