Latest short-range forecasts from the Korea Meteorological Administration and global models like ECMWF and GFS point to a Seoul high of 14-16°C on March 28, driving the tight clustering of trader odds around these outcomes with 15°C at 17.5%, 14°C at 17.0%, and 16°C at 16.5%. A mild high-pressure ridge over the Korean Peninsula will advect warmer southerly air, tempering typical late-March averages of 11-13°C, though variable cloud cover and urban heat island effects in Seoul introduce 1-2°C uncertainty in diurnal maxima. Historical data shows March 28 highs rarely exceed 18°C (top 10% percentile), explaining low odds there, while sub-12°C tails reflect fading cold air influence post-recent frontal passage. Traders await today's final KMA update for resolution cues.
