Trader consensus has locked in 16°C as Tokyo's highest temperature on March 24 at virtually 100% implied probability, driven by the Japan Meteorological Agency's (JMA) latest forecast models converging on this precise value amid a stable cool air mass dominating eastern Japan. Ensemble predictions from ECMWF and GFS align closely, showing minimal spread around 15-17°C with historical late-March averages near 13°C supporting subdued warmth from prevailing northerly flows and clear skies limiting solar heating. Realistic challenges include an unforeseen southerly wind shift or marine layer breakdown, but current upper-air patterns and low model uncertainty make deviations above 17°C improbable without major synoptic changes.
