Met Office forecasts for March 27 in London indicate a maximum temperature of 12°C, driving the 98.8% trader consensus as cool northerly winds and a blocking high-pressure ridge maintain subdued conditions across southeast England. Latest ensemble model runs from the UKMO and European Centre for Medium-Range Weather Forecasts (ECMWF) cluster tightly around this value, corroborated by recent observations from Heathrow showing daytime highs struggling to exceed 12°C amid cloudy skies and scattered showers. March climatology supports this, with typical maxima of 11-13°C, and no signals of warming advection in current upper-air analyses. Realistic challenges include a jet stream dip allowing southerly flow or prolonged clear skies boosting solar heating, with final hourly updates expected by evening.
