Korea Meteorological Administration short-range forecasts project Seoul's highest temperature on March 28 at precisely 12°C, under mostly cloudy skies with a 60% chance of light rain, northeast winds, and high humidity around 65%, driving the market's overwhelming 99.9% implied probability on this outcome as trader consensus reflects this high-confidence guidance from official models and observational data. Global ensemble models align closely, capping daytime warming due to persistent cloud cover suppressing solar insolation amid a cool spring air mass typical for early March in Seoul, where historical highs average 10–12°C. Realistic challenges include unexpected prolonged clear skies boosting insolation for a 1–2°C spike or urban heat effects at peripheral stations, though low-probability given current trajectories; intraday KMA updates and final evening observations will confirm the peak reading before market resolution.
