Recent model runs from Open-Meteo and GFS indicate that a cold front clearing on October 14 will yield partly cloudy skies over Incheon on the 15th, promoting radiational cooling and minimum temperatures likely between 10–14 °C under light southwesterly flow. Ensemble guidance shows modest spread around the overnight low, with some members holding near 10 °C while others remain closer to 14–16 °C depending on cloud cover and wind. Traders have priced the 15 °C outcome highest because it aligns with the central tendency of current deterministic and ensemble forecasts, while the clustering of probability across adjacent lower bins reflects lingering uncertainty in boundary-layer mixing and exact cloud timing ahead of the next data release.
