Latest Met Office and ECMWF forecast ensembles indicate a maximum temperature clustering tightly around 12-13°C for London on March 27, fueling the razor-thin trader split with 12°C at 52.5% implied probability and 13°C at 47.5%. A high-pressure ridge building over the UK is advecting mild Atlantic air, boosting daytime highs above the March climatological average of 11°C, but low stratiform cloud cover and subtle timing differences in solar insolation create model spread of just 0.5-1°C. Ensemble means favor a slight 12°C edge amid boundary layer stability. Key upcoming data includes tonight's 00Z model updates from NOAA and UKMO, potentially clarifying peak hourly readings.
