Recent official forecasts from the Met Office and European models indicate a mostly cloudy Saturday with widespread rain and southwest winds of 10–15 mph, limiting daytime solar heating and supporting a maximum temperature near 20–22°C in central London. Persistent cloud cover and precipitation timing create the narrow spread among leading outcomes, as even modest breaks in cloud could push the peak toward 22°C while heavier rain keeps it at 20°C or below. Ensemble guidance shows limited model divergence at this short range, though small shifts in frontal timing remain the key uncertainty ahead of final observations.
