The Japan Meteorological Agency's latest guidance and global model ensembles like ECMWF and GFS project Tokyo's lowest temperature at Haneda Airport station on May 18 near 17°C, capturing 24% trader consensus amid fragmented odds reflecting inherent short-range uncertainty in nighttime boundary layer processes. Persistent northerly winds from a weak upper trough have kept recent lows cooler than May climatology (historical mid-May average ~16°C), as seen in May 13-15 actuals around 14-17°C, but variable overnight cloud cover differentiates outcomes: partial clearing favors radiational cooling to 17°C, while thicker stratus could trap heat toward 19-20°C. JMA's next 00Z/12Z updates on May 16-17 may refine steering patterns ahead of resolution.
