Recent official forecasts from the Met Office and other models indicate an overnight minimum of 16–17°C in London on 28 August, driven by a mild southwesterly airflow, moderate southwest winds of 10–15 mph, and variable cloud cover that limits radiative cooling overnight. Thunderstorms and heavy rain on 27 August have given way to clearer intervals, but lingering humidity and a 30–45% chance of showers keep the surface layer from dropping sharply. Historical August minima average near 14–15°C, yet the current warmer, more humid airmass and lack of clear anticyclonic conditions support the market's tight 16°C (42.5%) versus 17°C (36%) split. Updated model runs overnight will clarify whether localized clear spells push the low toward 15°C or hold it at 16–17°C.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
