Met Office forecasts for March 29 in London project a daytime high near 11°C under a stable high-pressure system channeling cool northerly airflow, aligning with traders' 36% implied probability on that outcome and 20% on 10°C, while pricing warmer readings like 13°C or higher below 10%. Recent ECMWF and GFS ensemble runs over the past 48 hours have tightened consensus around 9-12°C maxima, down from earlier milder outlooks amid a jet stream dip, with Heathrow observations showing overnight lows of 4-5°C that cap warming potential. Climatological March 29 averages hover at 11°C, but low cloud cover and light winds reduce upside risk; watch for tomorrow's 12Z model updates that could refine probabilities ahead of resolution.
