Recent forecast model runs and Met Office guidance point to a mild overnight period on August 18, with the lowest temperature most likely falling between 17–19 °C. Light rain or passing showers expected that evening will increase cloud cover, limiting radiative cooling and keeping the boundary layer warmer than under clear skies. A westerly flow advecting milder Atlantic air further supports these elevated minimums, consistent with the market-implied probabilities favoring 18 °C (41.5 %) and 19 °C (22.5 %). Updated guidance later today could refine wind speeds and cloud timing, potentially shifting probabilities if clearer conditions allow greater overnight cooling toward the 17 °C or 16 °C bands.
