Japan Meteorological Agency forecast models indicate a strengthening high-pressure ridge over the Kanto plain, bringing clear skies, light southerly flow, and intense afternoon solar heating that positions Tokyo for a daily maximum of 28°C or higher on May 18. Ensemble guidance clusters tightly around 28–30°C, well above the mid-May climatological average of 23–25°C, driving the market’s 67% implied probability for the leading outcome. Traders are monitoring the final JMA model runs and surface observations ahead of tomorrow’s diurnal peak, with resolution based on official Tokyo station records. This setup reflects typical warm-sector patterns under similar synoptic conditions, though minor forecast adjustments remain possible.
