Japan Meteorological Agency forecasts pinpoint a high of 15°C for Tokyo on March 22 under partly cloudy conditions with light northerly winds, anchoring the market's 95% implied probability on this outcome amid trader consensus. This projection draws from ensemble models like ECMWF and GFS, which converge on stable cool spring air masses consistent with Tokyo's late-March climatology—historical highs averaging 13-15°C from 1991-2020 JMA data. Minimal updates in the last 48 hours, including subdued jet stream activity, bolster confidence. Challenges could arise from a sudden southerly warm front or urban heat amplification, but model uncertainty bands keep deviations above 16°C below 2%.
