Met Office forecasts indicate a maximum temperature of 14°C at London City Airport on May 15 under predominantly cloudy skies with a 40-60% risk of showers and northwesterly winds gusting to 20mph, driving trader consensus toward 13°C and 14°C as leading outcomes. A lingering low-pressure trough following a recent cold snap has suppressed temperatures below mid-May climatological averages of 17-18°C, with limited solar insolation from cloud cover differentiating the tightly matched probabilities—denser showers during midday peak heating could cap highs at 13°C, while brief sunny breaks might push to 14°C or rarely 15°C. Model ensembles show low spread but inherent short-range uncertainty; watch afternoon observations and evening forecast updates for shifts ahead of resolution.
