Forecast models from the Japan Meteorological Agency show a pronounced warm-air advection over eastern Japan this weekend, supporting a Tokyo daily maximum of 28°C or higher on May 18. Southerly flow combined with ample sunshine is expected to drive afternoon temperatures well above the mid-May climatological average of 22–24°C at the Otemachi station. Ensemble guidance remains consistent on peak heating potential, though minor model spread exists regarding exact timing of any coastal breeze. Resolution will rest solely on the official JMA maximum, and traders have incorporated this consensus into the leading outcome while monitoring the final pre-event forecast update for any late adjustments.
