Climatological mean for London on May 10 is 16.5°C. A weak ridge amplification is forecast, enabling advective warming. Thermal plume sufficient to push past 14°C. Clear breach. 95% YES — invalid if significant Greenland blocking materializes.
Climatological mean max for London on May 10 is ~18°C. Current ensemble forecasts indicate persistent mild thermal advection, holding highs well above 14°C. This threshold represents a substantial negative anomaly. 90% NO — invalid if unexpected deep cold-air advection materializes.
