Japan Meteorological Agency forecasts and global models like ECMWF and GFS drive trader consensus toward a Tokyo high of 16°C (40.5% implied probability), with 15°C and 17°C close behind at 25.5% each, amid mild late-winter conditions featuring a high-pressure system fostering daytime warming. Recent Tokyo observations show highs reaching 14-15°C in preceding days, above the March 22 historical average of ~13.5°C, influenced by a retreating polar vortex and southward jet stream shift enabling warmer southerly advection. Urban heat island effects amplify peaks slightly, but stable weather patterns suppress extremes, keeping sub-14°C or 18°C+ odds below 3%. JMA's final afternoon update could refine these mid-teen probabilities.
