Persistent heatwave conditions driven by high pressure and warm southeasterly flow from the Met Office and ECMWF models keep London's overnight minimum temperatures elevated for August 14, with consensus forecasts centering near 18–20°C. Clear skies and light winds reduce radiative cooling overnight, while the warm air mass aloft limits deeper drops, shifting trader-implied probabilities toward 21–23°C. Recent updates show daytime peaks of 33–37°C sustaining the warmth into the evening, though a gradual cooling trend may begin by the weekend. These factors explain the tight clustering around 22°C at 52% implied probability, reflecting the narrow range of plausible outcomes given current atmospheric patterns.
