Trader consensus on Polymarket reflects tight uncertainty in short-range forecast models for Tokyo's April 6 high temperature, with Japan Meteorological Agency (JMA) and ensemble guidance like GFS and ECMWF diverging by 2-3°C around 21-23°C due to variable cloud cover and late sprinkles under a weak high-pressure ridge. Recent warm spring trends—early cherry blossom full bloom from March heat—support potential for 23°C or higher if insolation dominates, but overcast conditions forecast post-rain on April 5 could suppress peaks to 21°C by limiting solar heating. Historical April averages hover at 19°C, yet current mild southerly flows favor above-normal warmth; watch JMA's daily updates through April 5 for refined frontal boundary positioning that will clarify the outcome.
