Recent forecasts from the Korea Meteorological Administration highlight a southerly flow of warmer, moist air across the Korean Peninsula, reinforced by above-average Yellow Sea sea-surface temperatures, as the key driver pushing market-implied odds for a Seoul high of 25 °C or above to 79.5 %. Ensemble guidance from global models shows afternoon maxima likely settling in the mid-to-upper 20s Celsius under partly cloudy skies, consistent with mid-May climatology yet elevated by these persistent synoptic patterns. With resolution tomorrow, traders are monitoring the final model runs and any last-minute shifts in steering flow that could cap the peak just below the threshold.
