Korea Meteorological Administration's latest forecast pins Seoul's March 19 high at 9°C, driving near-unanimous trader consensus with 100% implied probability, as ensemble models from ECMWF and GFS converge on this outcome amid persistent cold northerly winds and cloudy skies suppressing temperatures. Historical March data shows Seoul averages 11-12°C highs, but current synoptic patterns—stagnant high-pressure ridges and low solar insolation—align with verified soundings and satellite imagery supporting the cool projection. Realistic challenges include a sudden foehn wind event or frontal breakdown accelerating warming to 10°C+, though surface observations today at 5-7°C indicate low upset risk barring model divergence in final hours.
