Recent Met Office forecasts indicate clearing skies overnight into September 26 after earlier rain, with light northwest winds and radiative cooling under partly cloudy conditions supporting a minimum around 12–14 °C in London. Model consensus from GFS-derived outlooks and European sources aligns on overnight lows near 13 °C, reflecting typical early-autumn boundary-layer cooling rates without strong advection or cloud cover to retain heat. Trader positioning around 13 °C at 52% implied probability reflects this stable guidance, while lower outcomes like 10 °C capture potential for localized frost pockets or model underestimation of cooling; updated Met Office briefings and any late shifts in high-pressure positioning remain key near-term catalysts.
