Tight clustering of probabilities around 10–11°C reflects the latest Met Office and ECMWF ensemble forecasts, which project London's highest temperature on March 25 at 9–12°C amid a transitional spring pattern with weakening Atlantic highs and encroaching cooler northerly flows. Recent 12Z model runs show a slight downward nudge from earlier warmer outlooks, driven by a deepening low-pressure system over Scandinavia pulling chillier air southward, differentiating 11°C (top odds at 31%) from 10°C (30.5%) via 1–2°C spreads in boundary layer temperatures. Historical March 25 maxima average 11°C at Heathrow, but cloud cover and light showers introduce variability; traders eye evening updates for frontal timing shifts that could tip outcomes.
