Japan Meteorological Agency's April 3 afternoon forecast projects a high of 25°C at Tokyo Haneda Airport on April 5 under cloudy skies with 50% chance of scattered showers, reflecting a persistent warm anomaly driving early cherry blossom full bloom and above-normal spring temperatures. Trader consensus clusters implied probabilities around 21–23°C (27.5–29.5%), as cloud cover and potential showers could limit solar insolation and peak heating despite southerly winds advecting mild air from the Pacific. Ensemble model spreads highlight uncertainty in frontal timing and precipitation intensity, with historical early-April highs averaging 17°C but recent days warmer amid high-pressure ridging. Watch JMA's next 17:00 update on April 4 for refined guidance ahead of resolution.
