Korea Meteorological Administration's short-range forecast projects Seoul's highest temperature on May 10 at 25°C under mostly clear skies and light southerly winds, driving trader consensus to 100% implied probability for 22°C or higher. Morning observations at Seoul station show temperatures rising from 12°C with 0% precipitation risk, enabling typical diurnal heating amplified by a stable high-pressure ridge over the Korean Peninsula. Global models like ECMWF and GFS show strong agreement, a shift from cooler highs of 19-20°C earlier this week. Realistic challenges include sudden cloud cover or northerly gusts capping peaks below 22°C, though upper-air patterns render this improbable; monitor hourly KMA updates through afternoon for final measurements.
