Korea Meteorological Administration short-range forecasts indicate a high of 18°C at Incheon International Airport Station—the market's resolution point—for April 12 under partly cloudy skies with light winds, anchoring trader sentiment with 31.5% implied probability on 18°C. This follows a warming trend from recent cool highs near 12–14°C on April 9–11 amid lingering cold air, as high-pressure ridging builds. Global model ensembles from ECMWF and GFS exhibit significant spread clustering around 17–20°C, reflecting uncertainty in cloud cover limiting solar insolation, southerly wind strength for warm advection, and low precipitation risk. Key variables tipping outcomes include afternoon clearing versus overcast persistence; final KMA hourly updates today could refine guidance before observations resolve the market.
