Historical Tokyo May 5th climatological data shows lows frequently below 15°C (e.g., 2023: 13.9°C, 2022: 12.3°C). Current mesoscale models lack strong advective warming. The urban heat island effect won't negate overnight radiative cooling. 95% YES — invalid if a strong high-pressure ridge develops before 5/5.
Tokyo's May climatological profile shows average lows near 15°C; -15°C is a near-impossible >5-sigma anomaly. No synoptic pattern supports such extreme isotherms. Strong 'no' signal. 99.9% NO — invalid if a sudden stratospheric warming event drastically alters polar vortex behavior.
