Japan Meteorological Agency's latest forecast, updated March 29-30, projects Tokyo's April 4 high at 18-19°C under cloudy skies with 50-60% scattered shower probability, anchoring trader sentiment in the tight 17-20°C cluster where outcomes trade within 24.5-21.0% implied odds. Differentiation stems from uncertainty in cloud cover and precipitation timing: reduced insolation from overcast conditions or evaporative cooling from showers favors 17-18°C, while partial clearing or delayed fronts could yield 20°C via stronger solar heating. This reflects spring frontal variability, with GFS and ECMWF ensembles showing 2-3°C spreads around 18°C means. JMA's above-average April temperature outlook adds mild upside bias. Watch tomorrow's forecast refresh for shifts.
