Trader sentiment favors a Seoul high of 9°C on March 19 at 33% implied probability, narrowly ahead of 8°C (28.5%) and 10°C (17.5%), driven by the latest Korea Meteorological Administration (KMA) and ECMWF ensemble forecasts projecting mild early-spring conditions with peaks around 9°C. Differentiating these close outcomes are subtle model divergences: GFS runs hint at slightly cooler 8°C under lingering northerly winds from a fading Siberian High, while ECMWF shows potential for 10°C if diel heating strengthens amid partial cloud breaks. Historical March 19 highs average 10°C but vary ±3°C due to frontal variability; traders eye tomorrow's 12Z model updates for resolution amid typical short-range uncertainty in boundary layer forecasts.
